4 Benefits of Using Blazor Framework for Full-Stack Web Apps

JavaScript has disrupted the world of web apps. Using the language, developers can replicate beautiful, user-friendly interfaces on browsers. But what about .NET developers? They don’t really have this advantage.

But that’s about to change with the entry of Blazor by Microsoft. Just imagine, .NET  web apps running on a browser, without any plugins or coding wizardry. Unbelievable, right? 

Let’s learn more about Blazor, the fantastic .NET web framework that has taken the app world by storm. 

What Exactly is Blazor?

Blazor is a markup syntax, using which you can embed server-based code into your web pages. It is comparable to Angular or React, the only difference being that it is powered by C#. Based on the latest web standards, Blazor doesn’t require any add-ons or plugins to work. 

As a result, Blazor bundles full-stack app development with the same consistency, stability, and productivity that .NET provides. Moreover, Blazor is completely open-source since it is implemented through WebAssembly. 

WebAssembly is the secret sauce that makes this magic possible. It is a web standard that converts high-level languages to a simplified form that runs at the speed of native machine codes. Thanks to this groundbreaking platform, code based on sophisticated languages like C# and F# can be run on web browsers. 

Now, let’s read about all of Blazor’s benefits below.

Advantages of Creating Full-Stack Web Apps Using Blazor

Blazor has the same benefits that a modern-age single page application (SPA) like Vue or React offers. Plus, both the client-side and server-side coding can be done using the same .NET technology. This means you can reuse the same classes on both sides.

In short, web apps built on the Blazor framework are fast and native-like. Their code is customizable, secured, and shareable. Let’s take a look at all the advantages of Blazor-based development.

1. You Can Run .NET Code in Browsers 

Until Blazor came out, JavaScript was the gold standard for full-stack web apps. This means back-end .NET developers had no option than to learn JavaScript if they wanted to ace full-stack development. 

With the advent of WebAssembly, the monopoly that NodeJS enjoyed in app development comes to an end. Via client-side Blazor, the same validation code can be used for all in-browser logic.

2. It Is Faster than JavaScript

If you use the client-side Blazor framework, you can develop performance-intensive apps like video gaming and augmented reality easily. Plus, Blazor is pre-compiled into WebAssembly so your server-side code is deployed and run faster than in languages like JS. As the full-stack cycle progresses, the deployment completes and code execution becomes even faster. 

You may not notice the speed difference in simple codes, but the difference is palpable in sophisticated programs.

3. Codesharing Is Possible on Server and Client Sides

Often, the same validation code that is run on the client-side needs to be executed on the server-side. 

For instance, you can tell users that they have entered a non-existent username as soon as they enter it, to save them a round trip to the server. Then, the same validation code is implemented on the server-side just to double-check the user input for the pre-fed username logic.

When you use Balzor, you create a class library with the validation algorithm and add the library as a reference to your user-facing Balzor app and the server-side app. This way, the same bit of code is deployed but without writing the class twice. Naturally, you save a lot of effort and development time.

4. Blazor-Powered Apps Can Run Offline

Blazor-run apps don’t consume too much network bandwidth since the server-side Blazor doesn’t pass data to the server time and again. Once users download the app from the internet, they can use the app completely without web support, with no impact on speed or performance.

Does this mean that Blazor is flawless? To answer this question, let’s look at its drawbacks.

Is Blazor Just Hype?

With a recent roll-out in May 2020, Blazor is still in the infantile stage. It has, thus, quite a few disadvantages that the team hopes to iron out as the framework matures.

1. Huge Payload

As of now, a fresh Blazor project weighs around 2.4MB. Since the entire server-side code needs to be shipped onto the client-side, the payload inflates. This means that even if your code contains a few lines only, the app size can run into megabytes. 

2. Long Initial Load Time

If your users have poor internet connectivity or are working on non-standard browsers, they can get frustrated with long load times. They have to wait out the period when the WebAssembly is downloading and static files on the server-side are being created.

3. Restricted Runtime

Blazor apps are subject to the same browser sandbox restrictions as JavaScript apps. If you’re working with thin clients, you may have to install polyfills to boost runtime. This is not recommended as you can lose many performance benefits of Blazor in the process.

4. Limited Debugging Capability

Client-side Blazor apps have their own custom debugging tab, but it has limited options. So, if your app has complex logic with hard-to-track bugs, you may have to write an initial code for debugging or place a huge amount of code into logging. To an extent, this nullifies the time-saving benefit of Blazor apps.

What is the Future of Blazor?

We wouldn’t be over-optimistic if we forecast a bright future for Blazor. Currently, there is a huge barrier to entry of .NET apps in the webspace. Blazor can help full-stack developers in this area. 

By poising itself as a single UI framework, Blazor demonstrates great potential. We see it growing in this direction and becoming a direct competition to JavaScript. As for the size and speed issues, the Blazor team is working overtime to streamline the programming kinks. We can hope for good news soon.

5 Steps to Improve Your KYC with Biometrics

KYC stands for “Know Your Customer.” It refers to the process where a business verifies the credentials and information of its potential and existing customers.

KYC is an essential step to prevent hijacking and tampering of sensitive customer data. It also helps businesses verify customers’ identities and assess their risk quotient.

KYC

Traditional KYC verification has many downsides, including restricted data portability and high costs. At the same time, vendors can’t exactly ignore KYC, especially as online transactions become rampant during COVID-19. 

To overcome the limitations of pen-and-paper identity verification, businesses have started leveraging next-gen solutions like biometrics. Let us talk about the advantages and best practices of using biometrics to streamline KYC. But first, let us understand why KYC is important and what are the issues with conventional KYC.

Why is KYC Important for Businesses?

Businesses, especially banks and financiers, rely on KYC for many reasons. A robust KYC system helps them to:

  • Thoroughly investigate new customers and verify their identities.
  • Prevent money-laundering and identity theft.
  • Assess the loan-repayment capability of clients.
  • Minimize potential security risks.
  • Comply with regulatory requirements.

Companies that don’t follow a stringent KYC procedure can expose themselves to fraudulent customers, insolvency, and reputation damage.

What Are the Drawbacks of Traditional KYC for Businesses and Customers?

Banks and financial institution have eliminated outdated KYC verification systems because of the following reasons:

1. Too Much Customer Friction

Customer-onboarding time has increased considerably ever since laws made KYC mandatory. According to a Thompson Reuters study, a simple account-opening process took 18% more time in 2018 as compared to 2017 since the verification time has stretched. 12% of customers say they got frustrated and switched banks when their bank asked for additional documents to complete complicated KYC.

Not only do customers have to wait longer for basic work, but they also resent the level of documentation they are asked to furnish. Privacy intrusion issues can arise when companies request for personal customer details.

2. High Compliance Costs

Companies are spending too much on legal fees and labor that are required to complete customer due diligence. Every week, 50% of bankers spend 1.5 days on onboarding new clients. The global compliance costs amount to $500 million annually for banks and finance-related businesses. If companies spend 15% to 20% of the total “bank-running” costs on compliance, risk, and governance, their profit margins dip.

3. Variable Data Rules

The list of permissible KYC documents varies from nation to nation. For example, Cyprus has recently updated their KYC requirements. They now demand an in-person meeting with each account holder. 

On top of that, there is no cognizance between companies when it comes to KYC rules. Different banks can ask for different verification documents from different clients. For instance, corporations may have to provide the director’s tax and legal papers. LLCs may be asked to furnish the Articles of Organization, etc. 

Compliance requirements depend on the Central Bank’s dictates. Plus, banks might formulate their own compliance policies. With such fluid rules, it becomes difficult for customers to keep documents handy.

For all of the above reasons, biometric verification for KYC has become popular.

Biometric-based KYC is scalable, company-agnostic, and standardized. The collection of user data is fast, simple, and portable. Moreover, biometric provides more precise and reliable MFA multi-factor authentication) than knowledge-based authentication (KBA) like passwords or PINs. 

Last, biometrics can be based on facial-recognition, voice ID, or fingerprints. By disallowing shared user credentials, biometrics is the most secure authentication system for KYC and AML (anti-money laundering). 

5 Biometric Best Practices You Need to Follow

There’s no denying that biometric KYC is the way forward. However, to use this cutting-edge technology in the best way, you need to follow the tips below.

1. Allow Single-Sign-On (SSO)

Often, users find it challenging to remember multiple passwords. Biometric-enabled SSO enables users who fail to recall passwords, to sign in. Busy, multi-taskers enjoy the convenience and time-saving of SSO. Intel has already leveraged SSO to allow users to log in to multiple systems securely using a single username and password.

2. Integrate Anti-Spoofing features

The biometric system should include built-in security systems that risk-proof your KYC from imposters. Fingerprint scanners require a live finger not recorded finger pictures to complete the scan. Similarly, liveness detection ensures that the customer is a live one. Iris-pattern scanners may require you to move your eyeball or blink to pass the due diligence routine.

3. Include Multi-Factor Authentication (MFA)

To prevent data breaches, add a security layer by using MFA. It has two components—a custom pin that is system-generated, and personal authentication data (fingerprint, voice ID, iris pattern, geolocation, etc.). Mastercard’s “selfie pay” biometric system double-checks users’ identities by asking them to upload an instant selfie.

4. Take Advantage of Multi-Modal Biometrics

Typically, a single biometric data point is used to authenticate users. But background disturbances can distort voice tags and lighting can impact facial recognition. In such scenarios, authentic users can be locked out of systems. Also, a single data point is relatively easy to penetrate. That’s why some banks use multi-modal biometric KYCs that combine the results of more than one biometric. 

Your access control machines can be equipped with geolocation tracking and face scanners. Your bank locker systems can ask for voice identification along with eye patterns. This way, you can prevent spoofing even if one of your data points is compromised.

5. Be on Top of Trends

Identity verification is a fast-evolving space. Why so? That’s because fraudsters are always one step ahead of the legal system. As new ways of data leaks, account takeovers, and credit card frauds crop up, authentication systems also revamp. So, it is essential that you be abreast of trends in data security domains. 

If you use outdated, weak protocols, you are risking your customers’ financial and personal information. You are culpable for damages that your customers incur for your negligence and incompetence. Apart from the huge legal costs, you can also damage your business reputation and goodwill in the market.

Are You Ready to Improve Your KYC with Biometrics?

With SSN and KBA systems phasing out, biometrics-based KYC is the need of the hour. Since your customer relationships and business reputation are at stake, leave no stone unturned to master biometrics KYC. They offer convenience, cost-savings, and security to you and your customers.

How to Simplify User Onboarding for Product Development?

Imagine you are thrust into a new work environment, with no instructions or orientation. Everything, from colleagues to equipment, is unfamiliar. How will you feel? Lost in the woods, disoriented, overwhelmed? 

That’s exactly how a new user feels when he opens a new app or digital product for the first time and finds it bereft of proper onboarding. It’s no wonder that 25% of people abandon an app after the first use itself.

Source: Localytics

Now, envisage this situation: 

You enter an app, you are greeted by a warm welcome. Then you are explained how to set up the app’s features and hand-held through the registration process. You tend to feel confident at having hit the ground running. You are eager to explore the app and you may come back to it again and again. That’s how user onboarding helps in boosting user retention.

In this article, you will learn:

  1. What is user onboarding
  2. Why is it essential
  3. How to simplify it

Let’s get started.

What is User Onboarding?

User onboarding is a process where new users are instructed or guided through the product experience. It can be as simple as a greeting pop-up or as complex as configuration workflows.  The aim is to deliver value to users from the get-go and reduce drop-offs.

For instance, take a look at Hopper’s onboarding interface. Through a series of clean screens, the flight-booking app conveys its value proposition to first-time users.

A super-smooth onboarding experience sets up users for success. Users understand how to apply a product in order to extract maximum value. Let’s understand the other benefits of user onboarding.

Why Is Onboarding Your Users Necessary?

With countless apps available for every possible use case, it’s imperative that your app proves its worth from the outset. Seamless onboarding is one factor that keeps users hooked to your product lest they abandon you in favor of competitors.

Plus, it renders a favorable first impression. It’s likely that users considered your product useful when they first installed it. The onus to prove them right lies on you. If your product’s orientation is rough, customers feel disappointed and dejected. They pre-empt that the future journey will also be bumpy. In anticipation, they leave prematurely, even if your product holds promise.

Last, modern customers like to share their reviews on social media, which has become a conversation driver of sorts. Don’t be surprised if you find your app’s ratings falling and sign-ups dwindling. It’s quite possible customers frustrated by your onboarding ran on aggregator websites. And don’t count on word-of-mouth publicity or referrals at all.

To save yourself from all that trouble, follow the best practices of designing a pleasant onboarding experience.

Tips to Simplify the User OnBoarding Process

The right onboarding experience can boost your revenue, referrals, and customer lifetime value in the long-term. Take a look at some hacks that can simplify your onboarding strategy.

1. Design with a Customer-First Mindset

Getting a user to sign-up doesn’t qualify as a success from a business point of view. What good is earning a sign-up if the user doesn’t eventually convert? For converting people, keep an eye on the right metrics.

Don’t obsess over counting conversions or subscriptions. Focus on nurturing customer relationships. Equip users with tools and knowledge they would need to use your product efficiently. Make everything so simple and painless that they naturally glide towards check-out.

Some onboarding processes end with feedback, which serves no real purpose. The users have barely started using your product. It’s advisable to ask for a product review after they complete one whole app session. This way, they can provide more actionable perspectives.

2. Minimize User Fatigue

The drop-off rate among new users is almost directly proportional to user fatigue that cumbersome onboardings induce. If you ask too much personal data from new customers, they are bound to leave in a huff. You will naturally inject friction into their journeys. 

At the same time, gathering customer data is unavoidable to set up processes and preferences. To overcome the hurdle, track usage metrics and collate the findings to draw pertinent insights. Metrics like NPS (net promoter score) can be calibrated later, during product reviews. 

To keep onboarding seamless, don’t overwhelm new users with too many questions. Complying with regulatory protocols like GDPR can be attributed to complicated orientation. So, minimize data collection and let users in on the action as soon as possible.

3. Keep Onboarding Flexible

Some users are impatient to start their product journeys right after installation. For them, allow a “skip intro” option. But if your onboarding covers vital product features that all users should be aware of, keep popping reminders to get users to resume the intro.

Break user journeys into small, manageable sprints and guide users to where they are headed. Keep user resources and tools handy in plain sight. Nothing frustrates new users more than if they have to dig through an incomprehensible UX for transactional information. 

4. Optimize the Process Consistently

Onboarding should not be an afterthought. You need to plan for it during the product-ideation stage itself. Also, it is not a one-time deal. Depending on the user response to your onboarding mechanism, keep optimizing the process for the best results.

Once customers start using your product regularly, ask them for feedback through email or in-app surveys. You should also solicit improvement suggestions and try to incorporate them into your process on priority. Don’t forget: your products are successful only if they satisfy user intent and expectations. 

Ready to Nail Your User Onboarding?

User onboarding is critical to foster customer loyalty, conversions, and retention. Your onboarding needs to be simple and anchored around customer needs. Keep your mantra straightforward: sign up users easily, deliver value quickly.

How Cloud Applications Can Help Bring Mobility and Agility?

“Cloud hosting” is no more a buzzword or a passing trend. It’s truly come of age, with Gartner predicting the public cloud market to grow by 6.3% in 2020. But why this sudden craze for cloud hosting, have you wondered?

It’s quite understandable. Cloud hosting provides agility and mobility to businesses. It enables companies to adapt and respond faster to evolving market conditions and customer behaviors. By harnessing cloud-power, businesses can gain a competitive advantage, which is so essential today.

Apart from that, here are the main advantages of being an “agile” business:

  • Revenue grows faster
  • Business costs reduce
  • Reputation management becomes effective

In this post, we will discuss why businesses need to be “agile” and how the cloud helps them to ace this area.

Top Ways How Cloud Applications Make Businesses Agile?

Take a look at the main benefits of cloud applications to businesses.

  1. They Facilitate Easy Scale-Up and Down

There are times when your business may need to scale operations and resources on-demand. By hosting your software on the cloud, you ensure that you are paying only for the resources that you are actually utilizing. In this way, cloud apps minimize wastage and overheads in a big way.

On the other hand, if you maintain huge infrastructures on-premise, there arises a problem of redundancy when you have to scale down operations. You not only lock a lot of capital in procuring extra resources that are no more productive but also incur maintenance costs to keep them running.

  1. They Make Business Data Available Anywhere, Any Time

With the cloud housing all your business data, your teams can work remotely from any location. Internal and external collaboration on projects is possible when data is decentralized as with cloud applications.

Your time-sensitive work can go on uninterrupted since all related information is available in the cloud. Inter-departmental projects can run seamlessly if project managers configure data-access permissions correctly.

Compare this with in-house data hosting. A lot of additional work and time gets wasted in getting access to siloed data. Plus, changes and updates done to data do not get reflected instantly and universally, which can be a problem, especially for projects spread across different departments or time zones.

  1. They Ease Testing and Updation

Updating systems becomes easier with cloud applications. This is especially true for managed cloud services. When a cloud service provider looks after the updation part of your business, your teams are free to invest their time and expertise in productive tasks. This improves the overall productivity of your business.

Testing is also a breeze when it comes to cloud applications. First, you can reduce capital expenditure (CAPEX) since you don’t have to buy or maintain costly testing equipment. Second, tested solutions can be quickly deployed since the cloud manages them. Last, your entire testing environment becomes more responsive and cost-efficient.

  1. They Reduce Complexity of Business

In a survey of business executives, 66% of respondents said that cloud applications reduce business complexity. But how does that exactly happen? Cloud makes your business processes simple, improves the distribution of resources, facilitates collaboration between teams, speeds up rollouts of complex business processes, and boosts the ability to access and share business data.

  1. They Optimize IT Budgets

Since cloud applications run on the pay-per-resource model, they are more economical for budgeted organizations. You can control capital expenditures on resources and limit usage to stay within your set budget.

Plus, you can easily allocate budget for resource expenditures and do financial planning more efficiently. In this way, you can keep a margin for unexpected expenditures and avoid cash crunch.

  1. They Help in Long-Term Strategizing

IT teams are not burdened with maintaining resources and infrastructure. They have the bandwidth to devote energy to customer communications and business planning. In this way, you can meet organizational goals more efficiently.

Final Thoughts

As you can see, the cloud boosts business agility and mobility in many ways. That’s why many businesses are moving their operations from on-premise to in-cloud. By doing this, they gain a competitive edge, reduce capital investment, allow teams to collaborate better, facilitate proactive decision making, and plan business processes with ease.

Are you thinking about migrating to the cloud as well? If you need assistance or guidance for the big move, feel free to reach out through the comments section. We are always happy to help our readers. Rest, watch this space for more ground-breaking posts on cloud computing and other IT aspects.

5 Tips for Easy User Onboarding

So you built a software application successfully? Great, that’s good news. But are you confident that you can convert sign-ups into active users? Are you sure your app can onboard users smoothly, convince them of its unique value proposition (UVP), and get them to start using it from the get-go?

Before you answer those questions, take a look at the stats on user onboarding:

  • 25% of apps are abandoned by users after the first use itself. 
  • 77% of people uninstall an app within 72 hours of installing it.

We don’t want to sound negative but the truth is that user onboarding is a sore point with app vendors. They often find it challenging to retain and turn first-time users into loyal users. 

That’s why, in this post, we will explain 5 effective tips for user onboarding, with relevant examples from super-successful apps.

Let’s get started.

How Can You Onboard Users Successfully: 5 Tips

Here are the best practices of user onboarding that every app developer should follow:

  1. Keep Things Simple

In a Clutch survey of 501 app users, 72% of respondents said that a quick and simple onboarding process plays an important role in their decision to keep using the program. 

Keep the onboarding steps to a minimum and ensure that they can be completed within a minute. Ask for personal contact details (mentioning reasons why they are needed) and show only essential UI elements in the first use. Try not to overwhelm new users by asking them for unnecessary permissions. 

For instance, a movie-booking app needs only location-access and SMS-sending permission. They should skip requesting permissions for contacts or camera. Those can come at later stages once users are comfortable and confident of the app.

Example: WhatsApp

WhatsApp’s user base is unbeatable. According to their CEO, Jan Koum, one of the biggest reasons for the app’s success is its simplistic onboarding process.

The app self-detects the SMS with the verification code that is sent to first-time users. This means users need not leave the app interface and dig through their inbox for the SMS.

  1. Allow Skipping Steps

Many tech-savvy users don’t like to be hand-held through the onboarding steps. They like to explore their new installs themselves. To such users, give the option to skip whole or part of the onboarding process. There is no burning need to take them through the grand tour when they are impatient to try the app for themselves.

Vevo, the popular music-streaming app, found that logins increased by 10% when they included the “Skip” button in their app. If you’re not clear about your users’ preferences, conduct usability testing with different variants of the onboarding flow. Then, deploy the variant that works best for your users.

Example: Slack

Slack puts users in the driver’s seat by giving them a “Skip the Tour” option in every screen of the onboarding stage. Users can move to the main interface as soon as they feel confident enough to start using the app. 

  1. Ask for Permission

It’s a good practice to ask permission before sending push notifications to new users. 

The Clutch survey we cited earlier found that 4 out of 5 users like to know why an app needs to know their personal details, payment preferences, or device permissions. In fact, this small step can improve opt-in rates in a big way.

Example: Letgo

Letgo is a reputable portal for buyers and sellers of used items. Instead of accessing users’ inboxes directly, they send notifications to them every time a customer expresses interest in their listed items. In this way, users feel they are in control of their app engagement.

  1. Demonstrate Value Instantly

People install your apps for a reason. They have certain expectations from your app. If the app is unable to fulfill these expectations promptly, customers churn quickly.

So, think of an efficient way to demonstrate value to new on boarders: set up a features carousel, product walkthrough, or new-user registration. Just focus on showing what benefits uses derive from the app.

Example: Venmo

Venmo is a payment wallet with social-sharing capabilities. It lets users share their payment histories with friends. To reinforce their app’s credibility, on the first screen itself, Venmo shows social proof about how popular and reliable their platform is. This inspires confidence from new users who are apprehensive about sharing their payment info with a new app.

  1. Provide Incentive for First Conversions

Encourage users to keep using your apps, give them incentives to convert for the first time. 

For example, you can provide exclusive features or promo codes to users who fill out the registration form or make their first purchase. Other incentives can be loyalty points or in-app credit.

Example: UberEats

Uber’s food-delivery brand, UberEats, make the onboarding process really frictionless for new users. 

As soon as users register, they are welcomed with a coupon for a $20 discount on the first order. If that’s not enough to entice users to order, a list of nearby restaurants displays on multiple screens.

Conclusion

We can not help but emphasize how critical your user onboarding process is. If you’re able to onboard users painlessly, take it as a big win. With the app space getting crowded and apps competing for user attention, your onboarding process can help you get a competitive edge.

So, think up an efficient process to onboard new users. A/B test your onboarding models to find the best fit for your users and apps. Don’t hesitate to steal your competitors’ onboarding model if it’s good. You need a proven onboarding strategy to get your app up and running in no time.

Do you have any questions about any of the above strategies? Drop them in the comments and we’ll answer soon. Watch this space for more revelations about app development and onboarding.

Top 8 Best Practices to Architect a serverless web application

Serverless computing has been gaining momentum ever since it came into limelight in 2015. It’s a native architecture of the cloud which enables users to create, deploy and run an application without thinking of its server. Serverless, in fact, allows users and developers to shift more the operational capacity, increase agility and innovation.  In short, you get limitless computational power with no infrastructure management tasks such as zero maintenance, cluster provisioning, capacity provisioning, etc. 

Top 8 Best Practices to Architect a serverless web app

Why Serverless

Serverless is the need of time. As technology advances, you need to come up with more enhanced web applications with more power and agility which may not be possible traditionally. And, even if it is possible, you need to spend a lot of effort such as building perfect infrastructure, human resources, time and cost. Serverless helps you remain focused on your core products while leaving all other responsibilities upon the serverless provider. All you need a serverless web application and you pay no heed towards its maintenance, scaling up, agility or anything else. You have immense benefits from having a serverless application. 

So, in this article, we shall be discussing the best practices of a serverless web application that every Serverless Architect should know.

Even though there are plenty of tech giants offering serverless services including AWS Lambda, Microsoft Azure, and Alphabet’s Google Cloud Platform, but we have taken the example of AWS to make it more comprehensive. So, here we go;

1. The Serverless Function Requires VPC-Enable for Better Security

We have taken an example of Lambda as most of us use AWS Lambdas as an event-driven, serverless computing platform. So, it is important to have VPC-enable functions of Lambda operate from VPC which is owned by AWS. Enabling this, you get complete ability to have your function make a network request to any address.

Lambda is not directly accessible to the public, but with the support of AWS APIs Getaway, we can make accessible for the public. So, be it accessing AWS APIs or interacting with AWS DyanamoDB APIs, you can easily do it after enabling the function for VPC access. So, having have your function VPC-enabled, the Subnet will manage all your traffic using its routing rules. 

2. Creating Event-Driven Architectures

When it comes to creating event-driven architectures, it is important to know the mechanisms and how to enable asynchronous messaging pattern. It applies in both creating a simple queuing and message buffering and choreography pattern that is more intricate even-based. To enable this, you need to use queues or streams.

Queuing is also used for intrapersonal communication. That means when you want to initiate communication between one Lambda function another, then Queuing can be the best for you.

3. How to Implement and Orchestrate in a Distributed, Microservices Environment

You need to implement coordinated transactions using coordinated sequenced invocations across services in distributed architectures. The implementation also allows rollback and retry mechanisms put in place. That is quite different from the traditional database-based ACID transactions. 

When you need significant orchestration logic and looking to utilize more of the orchestrator pattern, not the choreography pattern, then the serverless technology lie AWS Step Functions enables you to create highly qualified and complex workflows with its various AWS services that also includes AWS Lambda. 

4. Understanding AWS Lambda Computing Environment

It is important to understand AWS Lambda and programming model. You need to learn how to utilize Lambda in terms of performance and cost optimization. You learn this using the tutorial provided for AWS Lambda as “Lambda Under the Hood”, “Lambda Layers, the Runtime API, and Nested Applications” and “Optimizing Serverless Applications”. 

5. Serverless Deployment Automation

When it comes to a larger number of microservices and smaller components, integrating automation and code management into your application is critical. Given the fact that early integration will efficiently create, deploy and implement the serverless architectures. Importantly, when you use AWS, you get a wide range of first-party deployment tools and frameworks to properly architect your serverless web application. The tools and frameworks you can utilize from AWS include the AWS Serverless Application Model (SAM), the AWS Cloud Development Kit (CDK), AWS Amplify, and AWS Chalice.

Besides, there are various third-party tools and frameworks available to make the deployment of serverless web application easy, they include, Serverless Framework, Claudia.js, Sparta, or Zappa. You are free to create your custom-built framework, though you need to ensure that things such as automation strategy works as per use case, team and workflows. 

6. Identity Management, Authentication, and Authorization 

When it comes to creating a serverless web application, a developer requires planning things such as integrating identity management, building enhanced authorization and authentication functionalities in advance. The utilization of Amazon Cognito enables a developer to deploy these things directly into the serverless web applications. At the same time, when using Amazon API Gateway, the developers can manage things like authorization logic and permit requests straightforwardly. That means you manage the authorization logic at the gateway layer which protects your native authorization being exposed. 

7. Learning End-to-End Security Techniques 

Apart from knowing identity management, authorization and authentication, there are some more important security measures you can learn to create a highly secure serverless web application. Here are some of the top list of things you can consider;

  • Concerns regarding regulatory compliance
  • Ways to validate input and request
  • Metering & Throttling Access to tracking bandwidth and accessing use control based on rules
  • Securing storage and retrieving data as needed
  • IAM execution roles and implementing invocation policies 
  • And, others

You can learn all these things from the AWS tutorial page while creating the application. 

8. Considering Packages Size and Dependencies 

You must take care of package size as having a larger deployment package will slow down the function of the application. Therefore, you are advised to remove all the unnecessary items including documentation and libraries. You can use AWS SDK which enables Java function users to bundle the modules which needed from the SDK. 

Let’s take a look at the example of how using Java Function with AWS SDK create an excellent package;

<dependency>

    <groupId>software.amazon.awssdk</groupId>

    <artifactId>dynamodb</artifactId>

    <version>2.6.0</version>

</dependency>

Here, only the required modules have been used

In case, you are not using Java Function with AWS SDK, you end up creating a larger package with the entire SDK with lots of unnecessary modules. Here’s how it happens;

<!– https://mvnrepository.com/artifact/software.amazon.awssdk/aws-sdk-java –>

<dependency>

    <groupId>software.amazon.awssdk</groupId>

    <artifactId>aws-sdk-java</artifactId>

    <version>2.6.0</version>

</dependency>

Final Thoughts

When it comes to creating a serverless web application, you have plenty of things to learn. Serverless technology is the need of time as people need more services, support, and assistance from technology at the minimum costs. Serverless is the way to cut costs significantly and reward the business with limitless scaling options. Stay tuned for more such information.

Adopting right compliances with offshore development partner

What is an Offshore development partner’s purpose? To guide you through the process and to take care of your entire legwork. So you want a company with years of experience developing productive offshore teams.

They are supposed to understand the business, the culture and have seen everything before. Unfortunately, while many companies are calling themselves “offshore construction specialists” or others are providing “offshore outsourcing,” some are far away. 

Let’s look at how to test early doors for an offshore partner – ensuring that they’re genuinely trustworthy and professional – before you’re in too deep.

Offshore Development Partner

Are You Certain You Are Offshoring?

Offshoring and outsourcing are two very different models although they are often used interchangeably. The problem is that as offshoring becomes more popular, outsourcing firms want their pie slice, misleadingly advertising services “offshoring” or “offshore outsourcing.”

  • Offshoring-Building a dedicated software development team in another country (complete with office space, administration and management). Offshoring has many advantages, most importantly the savings and exposure to a vast pool of talent. You own the entire team and they are fully integrated into your company but your Offshore Production Partner handles the administration.
  • Outsourcing-Hiring vendors to cover a power deficit temporarily. These are more like freelancers. They are called in when necessary, but independent of your organization. Workload is outsourced in all industries, typically due to lower costs. And this is always fine. As a result, investing in a great offshore company has major cost benefits.

How to Evaluate Offshore Partners For Compliance

  • Test Their Demonstrated Expertise

It’s 2020: there’s no reason why your offshore partner’s website doesn’t display portfolio items or case studies. These can provide a perceptive view on what your offshore partner can do, and how well they are doing it.

Your prospective partner should be able to showcase their productive offshore development team building experience. The most important information, such as project strategy or relationships, schedules, outcomes achieved, should be highlighted. But check their delivery as well. Do they sound competent and confident, rude and showy, or maybe lazy and insolent?

Keep an eye out for fakes. If an organization really knows their job and accomplishments, they will be able to explain it concisely and make it easy to understand. Rambling words, ambiguous definitions, and unrealistic claims should all be red flags!

Take the time to research their past clients. What kind of feedback do they provide? It’s smart to check online reviews and double client testimonials that you see on their website. This legwork can save you a lot of trouble later.

  • Strike the Quality vs. Cost Balance

While cost saving is often the biggest incentive to offshore your work, it should not be at cost of quality. You don’t want to work with vendors who are cheap but can’t deliver quality work. 

So, how can you ensure that you’re getting value for money when you hire an offshore partner?

The cost of living in developing countries like India and China is lower than in developed nations like USA and Germany. So, you can be rest assured that offshore labor will be lower priced than domestic workers.

Even if you add taxes, utilities, administration, and duties, the grand total can be 50% to 30% lower than indigenous teams. Suppose you land a partner who offers to work for 10% of the domestic cost, you will be tempted to take up the offer. 

But you need to look more closely before jumping the gun. Ask the vendor some questions: 

  • What is the work-cost breakdown?
  • Are there any additional or hidden costs involved? 
  • What are the timelines and quality standards you expect? 
  • Does the vendor have the essential skill set and infrastructure to deliver the quality your expect?
  • Will you be asked to pay for hiring and training new people required for the project?

Get all terms and conditions written in a formal contract and iron out all the kinks beforehand. In this way, you can avoid disputes later and get the most bang for your buck.

  • Proactive about Communication

When your vendor is working thousands of miles away, communication becomes the key to smooth working. You will be surprised to know that one in five offshore projects fail due to poor communication. Clear communication cultivates trust between both parties.

project failure rate due communication

How do you gauge if your offshore partner will communicate proactively once the project commences. You will get inkling about this during your initial communication itself. Do they answer your emails and calls promptly? Do they adhere to the set meeting schedules? Any red flags at this stage should be considered seriously. If the vendor is careless about communication in early stages, they are bound to follow the same pattern later too.

  • Factor in the Culture Gap

Cultural gap can be an impediment to a great working relationship between offshore partners. But there are ways to work around it. The first step is that you need to acknowledge each other’s differences and be committed to bridge the gap.

When we talk about culture gap, it could be as wide as language barriers and as narrow as national holidays. Educate your vendor about the tenets of your culture and ask them to do the same. if the vendor has prior experience of projects in your country, it is a definite plus. 

They will have a pulse around the market condition and audience taste of the area. They will also possess knowledge about the communication protocol prevalent there. All these things become critical when you plan to spend months or even years working together. 

Final Thoughts

This list is by no means exhaustive. We have not touched upon technical competency and hiring, but those factors are already widely explored. It is the finer details covered in this article that we often miss when vetting offshore partners.

To sum up, you want an offshore vendor who is stringent about quality, communication, and commitment. At the same time, they need to have requisite experience and demonstrated performance. If you’re lucky enough to spot such a vendor, it makes sense to hire them even for a higher cost.

How to Ensure Data Quality for an Analytics Application?

Data quality is of paramount importance for an analytics application. Poor quality data can not only be misleading but also potentially dangerous. Data-driven decisions can get hampered and business intelligence (BI) gets affected if data quality is not maintained.

But the truth is that data quality issue was among the top three problems of BI and analytics users every year in The BI Survey since it was first started in 2002. If the situation is so dismal and its ramifications so profound, it makes sense to look at ways and means of remedy.

Data Quality for an Analytics Application

This post talks about actionable ways by which you can maintain high quality in the data pipelines of your analytics applications.

How Can we Define “Data Quality”?

Data can be said to be of good quality when it fulfills its dependent processes and becomes useful for its intended clients, end-users, and applications. Data quality impacts business decisions, regulatory mechanisms, and operational capacities.

There are five parameters by which we can determine data quality:

  • Accuracy: Is your data accurate and collected from reliable sources?
  • Relevancy: Is the data able to fulfill its intended use?
  • Completeness: Are all data records and values complete?
  • Timeliness: Is the data fresh up to the last minute, especially for time-sensitive processes?
  • Consistency: Can you cross-reference data from multiple sources? Is its format compatible with the dependent processes or applications?

How Can We Maintain Data Quality?

For an analytics application, data quality is non-negotiable. There should be a zero-tolerance policy for errors in data pipelines because this can impact the credibility and performance of analytics applications.

 In such programs, data is the raw material based on which deductions are made and decisions are taken.  If the raw material itself is sub-standard, the outcome will also be of poor quality. Hence, data quality in analytics applications should be a priority.

Below, we have outlined best practices and actionable steps by which you can improve and maintain data quality in your applications:

Data Quality for an Analytics Application_1

  • Data Profiling should be Rigorous

Often, data is collected by third parties or is submitted by multiple sources, which can be a reason for its dubious nature.  In such cases, quality of data is not guaranteed and a data profiling tool becomes essential.

A data profiling tool should check the following data aspects:

  • Format and patterns of data
  • Consistency between data records
  • Anomalies in data distribution
  • Data completeness

Data profiling should be automated and constant. You should configure alerts for instances when errors are detected. A dashboard with KPI metrics of data profiling should be maintained.

  • Avoid Duplication of Data

“Duplicate data” means the same content as an existing data set, in full or partial. Such data sets are generated by different people for different purposes and applications, but their content is exactly the same. The data set is collected from the same source and by using the same collection logic.

The problem with duplicate data is that it creates a cascading effect on all the applications that are using it. If a data source gets corrupted or a collection logic is erroneous, all the duplicate sets get affected and this can impair all the processes that involve the data set. It becomes difficult to remedy all the affected processes and track the source of leakage.

To avert this risk, you need to establish fool-proof data pipelines from start to finish.  Data modeling and architecture of each pipeline needs to be cautiously designed. Have a data governance system in place. Manage data in a unified, centralized system. 

You also need robust communication systems so that cross-functional teams can get a ring side view of what the other teams are doing.  If they detect any data duplication issues, they can raise an alarm instantly and issues can be capped at the origin itself.

  • Gather Data Requirements Carefully

You should document all data use cases, preferably with examples and visualization scenarios. Try to present data accurately. Communicate clearly with the client about their expectations from data discovery.

Keep all data requirements neatly filed and in a shareable mode so that the entire team can access them. You need business analysts in your development team because they understand perspectives of both sides, namely client and developers.  They also perform analysis of the impact that data requirements will have, plus create A/B tests to check all app iterations.

  • Data Integrity Needs to Be Enforced

You need data integrity measures such as triggers and foreign keys for your analytics application. As data sources multiply, you need to house them in multiple locations. Then, you have to reference data sets relatively. Data integrity ensures this referential system is error-proof.

They corroborate processes with best practices of data governance. With the advent of Big data, referential enforcement has become a complex yet essential module. Without it, your data can be outdated, delayed, or erratic. 

  • Lineage Traceability of Integrated Data Should be Easy

When data sets feed into each other, error in one record can offset a chain of errors that can paralyze the entire application. If you build lineage traceability, you can trace the origin of an error quickly and save impending disaster.

There are two aspects of this process: meta-data and data itself. In the former case, tracing is done by following relationships existing between records and fields. In the latter, you can drill down upon the exact data that has been compromised.

Meta-data traceability should be factored in during the data pipeline design stage itself. It is much easier to sift through meta-data than tons of data records. Hence, this mode should be incorporated in your app’s data governance policy.

Conclusion

You need to empower your data control teams to interweave best practices of data quality within your app’s architecture. It is important that you understand that your analytics app will be of no use to end-clients if its data quality is not pixel-perfect.

How to Select the Right Serverless Architecture: A Quick Comparison?

Businesses are benefiting from serverless architecture. They pay only for the services they use and get greater agility in return. Operational costs get lowered and developers can code uninhibitedly without worrying about hardware resource allocation. 

The biggest factor that works in favor of serverless architecture is the freedom to scale up and down as desired.  All these pros make a strong business case for companies that are planning to shift their selected workloads to the serverless model.

If you have already migrated to this disruptive technology or are planning on doing so shortly, these battle-tested tips and hacks can help you greatly. Using these suggestions, you can find the right serverless architecture provider for your business and then chalk out a working model that gives you the best returns.

Right Serverless Architecture

Which is the Best Serverless Provider for Me?

Your serverless provider will have long-term implications on your operations. The wrong selection can result in unimaginable loss in data, privacy, functionalities, and productivity.

There are many cloud computing providers who can help you set up your serverless architecture. But three platforms are undisputed leaders in the Function-as-a-service (FaaS) application model. They are:

  1. AWS
  2. Microsoft Azure
  3. Google Cloud

Let us compare their salient features so that you can make an informed decision for your business.

Features to select serverless architecture

Parameter #1:  Language Support & Deployment Options

AWS Lambda being the pioneer in serverless architecture finds widespread language support and deployment options. JavaScript, Node.js, Python, Java and C# give native support to AWS. It has a wide variety of runtime environments and is a versatile option for developers. Its API comes in a deployment package as a ZIP file which can be uploaded and edited directly in the console.

Azure AWS supports languages like C#, F#, Python, Java, Node.js, Python & PHP. It offers multiple deployment options, such as GitHub, DropBox, and OneDrive. You can also integrate it with Visual Studio and Zip Deployment.

Late entrant, Google Cloud, is supported by fewer languages, including Node.js 6, Node.js 7 and Python 3.7. More languages are expected to be appended in the list. For deployment, you have many options, such as Cloud Storage,  Zip Upload, CLI, and inline web editor.

Parameter #2: Management of Dependency

In AWS Lambda, you have to organize and align your dependencies with your code in a specific way. In this way, you create a deployment package. For doing this, you can use plugins such as Jenkins and Maven.

Azure Functions has the package.json built into your function directory. You can run npm install using the Console or Kudu in the Azure portal. This process is used universally, regardless of your choice of runtime language.

Google Cloud Functions allows you to manage dependencies via npm and lets you create a metadata file called package.json. Unlike AWS, Google install all dependencies on the user’s behalf. 

Parameter #3: Long-term Storage

The beauty of serverless architecture is that it is stateless. The functions written in this framework are not dependent on the underlying infrastructure and variables. AWS Lambda requires no use of variables while composing functions. But you can store variables in persistent locations like DynamoDB and cloud storage.

For Azure Functions, you may use Azure Blob Storage or Table Storage for storing persistent data across instances. In Google Cloud Functions, services such as Cloud Firestore, SQL, Storage, or Datastore should be used by your function is you want to share state.

Parameter #4: Access Management and Identity

Identity and Access Management (IAM) lets you control access to your functions by creating an authorization layer. Using this, you can decide what kind of resources you want (write-only or read-only) and what areas should these resources access (entire project or a single function only).

In AWS Lambda, you can create custom IAM policies and append to them your functions. Then, you can control users, roles, API actions, resources, and groups.

Azure Functions lets you create Resource Based Access Control for modulating function policies. Presently, you can grant read only/write only/ both rights.

Google Cloud Functions gives you more control as you can decide access permissions for each role. 

Parameter #5: Types and Triggers

Triggers are custom events or sources that invoke functions. AWS Lambda allows HTTPS-invoked events using REST API. There is also an endpoint which uses API Gateway. You can also use the wide variety of built-in AWS services. Functions can also be set off via AWS SDKs if you have the requisite permissions.

In Azure Functions, you can use services such as Queue Storage, Table Storage, or CosmosDB to create triggers. One add-on is that you can use external HTTP as well as WebHooks for invocation. 

Cloud Functions too supports HTTP triggers. You can also use Cloud Storage and Cloud Sub/Pub as triggers. New options are expected to be included in its Beta version.

Parameter #6: Orchestration

AWS has Step Functions that help to orchestrate serverless functions in a stateless architecture. Each function’s state is logged into a Step Function and used for subsequent functions.

In Azure Functions, Azure Logic Apps and Durable Functions accomplish the task of orchestration. Using connectors, you can integrate cloud services as well as on-site services. Google Cloud Functions suffers from a lack of orchestration capability.

Conclusion

The latest CNCF study reveals that AWS is the frontrunner among serverless architecture providers by claiming a market share of 70% deployments on Lambda. Its early advent and new updates are mostly responsible for its lead among competitors. But Google and Azure are fast catching up with their superb features and performance.

For newbies in serverless, our best advice is to give each provider a fair shot before making a final choice. You can evaluate each platform for compatibility with your custom software services, and choose the one which is best-aligned.

Get on a call with our expert to understand whether adopting serverless architecture for your web application is the right choice or not.

How to Make Your Websites ADA-Compliant?

We designate parking spaces and create raised markings on roads for helping the disabled. Now, we need to make our websites ADA-compliant too. ADA stands for The Americans with Disabilities Act which came into force in Jan, 2018. If your website or blog isn’t fulfilling statutes laid out by ADA, you can be issued a legal notice for non-compliance.

Why Do Websites Need to Be ADA-Compliant?

ADA compliance is a policy regulation for the inclusion of disabled people in all walks of life. The rationale behind the policy is that physically and mentally-compromised people should be able to access and use websites as well as normal people can.

What Will Happen If you’re not ADA-Compliant? Presently, nothing will happen. There have been cases where a link has been taken down after a complaint was filed with the authorities. But nothing drastic has happened as of now.  But what if the page taken down is one of your well-ranked pages? A page you built with years of careful SEO, back linking, and impeccable content? That will pinch quite a bit.

ADA-Compliant

Do You Need to Worry About This?

Not all companies need to pay heed to ADA compliance regulations. But if you’re in a public service domain, or are a government agency, or have 15 employees or more, you need to pay heed to ADA. Another way of determining this is: if your geographical location falls within an ADA-governed area, you will have to make your website compliant too.

Have you received a complaint or explanation notice for violation of ADA? Well, you’re not alone. Only 5-8% of government pages fulfill all the rules of ADA. Still, you need to be on the safe side of law at all times. 

Tips to Make Your Website ADA-Compliant

  • Understand the Web Content Accessibility Guidelines (WCAG)

Here are some of the recommendations mentioned in the WCAG:

  1. All non-text elements have a text alternative, barring some exceptional situations.
  2. All pre-recorded audio and video content has accompanying captions and audio descriptions.
  3. You have provided sign language references for all pre-recorded audio content.
  4. Instructions are not based solely on sensory characteristics such as size, shape, color, orientation, location, etc.
  5. Each and every text input filed can be programmatically determined.
  6. If a web page contains an audio that gets automatically triggered, there is a mechanism to turn it off within 3 seconds.
  7. The contrast ratio of text and images is not less than 4.5:1.
  • Conduct an ADA audit using the WAVE tool

Google Chrome’s WAVE tool is available at http://wave.webaim.org. You can type in your site URL and review the missing headings, descriptions, and other page structure related issues. The results will also show the ADA-related issues on that one page. We got 3 alerts and 0 errors on our homepage’s ADA evaluation.

Wave - ADA

 

  • Image Descriptions Should Be Complete

All the pictures and rich media elements you use in your site should have proper alt tags. Alt tags are used by page readers and players to describe the image to non-sighted users. If your images lack alt tags, they will be ignored by crawlers once Google starts penalizing sites for ADA-non compliance.

  • Design Your Site for All Users

If your site has illegible fonts or color contrast issues, it will not be of any use to handicap visitors. Similarly, CTAs, buttons, and links should be conspicuous and boldly displayed. Your page style and architecture should be so natural and intuitive that users of all levels can access information easily and painlessly.

Here are examples of good and bad ADA-optimized content:

ADA Example 1

ADA Example 2

  • Follow Copywriting Best Practices

Include white space in your web content judiciously. Write conversational content that is easy to read and digest. Break up large walls of text into small sentences and paragraphs. Organize page content using logical headings and sub-headings. For acronyms like USA, use a period between letters so that screen readers pronounce them correctly. These best practices will not only help your handicap customers but also delight your regular website visitors.

  • Check Your Site’ s Code

It’s always better to hire a professional site developer and designer look through your website’s HTML and CSS to make sure that there are no lacunas. Outdated content needs to be disposed and clean coding practices should be deployed.

ADA Compliance Checklist

We understand you’re busy growing your business yet want to be abreast with ADA regulations. Below, we have compiled a comprehensive checklist with the major points you need to cover in your website.

Data Point Yes No
All the images, audio/video files, plugins have alt tags?
Text descriptions accompany all complex graphics?
The alt descriptions specify the object’s purpose?
Blank alt tags are attached to graphics that are not clickable?
If an image is also a link, does the alt tag describe the link and graphics destination?
All videos have audio descriptions and captions?
All videos come with text transcripts? Is there a separate link to the transcript?
Are the videos embedded as web objects or present as links?
Tables have tags for identifying the row and column headers?
Layout tables don’t have row and column tags and headers?
No flashing images on pages?
Label tags are used for form controls that are text fields?
Are form fields in a logical tab order?
All plugins and applets in a page are available for assistive tools?
Is there a button for skipping navigation for people who are using screen readers?

Conclusion

There is one last point you need to understand. Making your website ADA-compliant is not a one-off effort. Rather, it is an always-on requirement that you’ll have to adhere as and when you add more content and link to other pages on the web.
