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.

How to Recruit Product Engineers

Product Engineers are changing the face of the product development domain. They are a step up from full-stack engineers and a level away from product developers. Simply put, product engineers are not plain coders; they code keeping user experience in mind. They not only understand technical stacks but also understand product design. You could call them “jack of all trades.”

How-to-Recruit-Product-Engineers_4

Do you get frustrated when your app’s features don’t reflect your vision? You had a perfect idea, precise product specs, technical resources, and tools, so what went wrong?

You missed the critical link between the design board and the market. You envisioned a product. You conveyed your idea to your designer. He communicated required technical specs to your engineer, who started coding. Where’s the collaboration? Where’s a continuous improvement? Consequently, you have a product that neither delivers ROI nor garners user acceptance.

Why Do you Need Product Engineers

If you have engineers who solve problems using code and product managers who take care of product features, why do you need product engineers? They are the critical bridge between design and development teams. By fostering two-way communication, product engineers ease friction between cross-functional teams. 

They code but with end products in perspective. Whenever presented with a coding opportunity, product-minded engineers evaluate how the code will impact the end product. More importantly, they think about user experience and business goals. They balance product specs with technical demands. The result is a product that meets market needs and business objectives- a win-win situation for all teams involved. 

You need a change in mindset here. Having product engineers in your team will create a pragmatic work culture with everyone striving towards building a winning product. 

How to Recruit Good Product Engineers

Product engineers need to have a blend of coding skills, analytical thinking, and business knowledge. A bit of creativity is a bonus. Plus, they have to be efficient managers and smooth talkers. 

How-to-Recruit-Product-Engineers_3

Step 1: Build a Job Description

Outline the proficiencies you desire in your potential product engineers. List their role and skillset categorically.

A sample job description could be: 

Product engineers will play a pivotal role throughout the development cycle, right from conception to testing. An astute understanding of market trends is necessary for the candidate.  

They need to be aligned with user expectations in a relevant niche. Once product specs are made, they will evaluate specs against market needs and re-align strategy to satisfy budget, time, and market constraints.

Product engineers will also have the responsibility to generate technical documentation and support material before a product is launched. They have to perform prototype testing for functionality, intuitiveness, and market appeal.

Add-on responsibilities can be assistance in the manufacturing process and guidance in packaging and marketing the product.

Step 2: Interview Candidates

Go in for a structured interview instead of a generic banter with candidates. Have multiple screening rounds spread across different days? Screen at least two candidates per day so that you can eliminate unsuitable people early. This will save you lots of wasted effort and time.

Divide the evaluation questions into:

  1. Career goal and inspiration
  2. Academic and professional background
  3. Coding proficiency
  4. Product-based thinking skill
  5. Project communication 

Take time to weigh each candidate. You need an all-rounder who will impact your future products in a big way. Determine a candidate’s worth after analyzing his capabilities carefully. Have a ballpark figure in mind and leave room for negotiation.

Sample screening questions can be:

  • Define our company’s vision and values.
  • Why do you want to join us?
  • What interests you in product development?
  • Explain the layers of full-stack.
  • What are the benefits and drawbacks of database procedures?
  • If a product designer lists five desirable features at the end product (give the features), how will you prioritize them?
  • Which setup do you prefer- MVC or some other?
  • What’s the use of the front-end framework?
  • How do you gather user feedback?
  • How important to you is product testing?
  • What team structure do you prefer- full-stacked or layered?
  • How can we scale our teams?
  • What makes a good mentor?

Invite questions from the candidate. Indulge in a discussion if opinions on a question vary widely. Try to gauge the person’s mindset and affinity. Are they concerned only about employee benefits? Do they have genuine concern about delivering classy products? How can they add value to your team?

Your recruiter’s job would include the following:

  • Study candidates’ body language: Make a note of how confident and composed a candidate is. Since this isn’t an entry-level job, you’d expect experienced candidates to not get nervous during interviews.
  • Don’t do passive listening: Listen actively to answers. Jot down your doubts and allow the candidate to clarify or rectify their answers. Reflect on previous answers. Also, refer to them in connected questions. This will show how genuinely a candidate is answering.
  • Make notes while interviewing: Prepare a checklist of must-haves and good-to-haves. Write down your observations succinctly. Highlight each candidate’s unique capability and its impact on the product development process. Summarize the interview answers into brief points. Read back answers to the interviewee and ask if you’ve understood them correctly. By doing this, you can avoid miscommunication.
  • Give instant feedback:  If you find an answer unsatisfactory, call it out immediately. Let the interviewee explain their viewpoint. Once the evaluation is over, don’t leave the candidates in a lurch. Communicate the next steps clearly. Don’t hesitate to end the interview early if you find a mismatch between your expectations and the candidate’s capabilities. 
  • At iViewLabs, we consider recruitment as a vital building block of team building and product delivery. We invest time and energy into it. You can do the same. To save bandwidth, delegate interviewing and screening responsibilities to experienced product managers. Brief them before so that they know what to look for in a candidate. Let them add to the questions and rounds since they are more in touch with the actual development process.

Let us know how you recruit product engineers. We would be glad to assist you with more helpful resources and free consultation. 

If you are looking to build a web, mobile or a cloud product, you can avail of a round of discussion with iView Labs’ tech team. Our developers and project team are always here to help and suggest what is required and necessary for your products.

5 Effective Ways of Retaining Product Customers

In a saturated marketplace such as ours where competition is stiff, it makes sense to conserve the customer base that you have acquired. It’s a well-accepted fact: if you service the customers you have, you won’t have to go around hunting for new ones. Yet, sales and marketing people exert effort and expenses in generating leads.

5-Effective-Ways-of-Retaining-Product-Customers_1

You can sell to an existing customer 7 out of 10 times, but only 1 out of 10 times to a new customer. Plus, acquiring new customers is costly. You can retain present customers at a fraction of this cost, one-sixth to be precise. And here’s the trump card of statistics in favor of customer retention: Gartner states that 80% of all your future ROI will come from just 20% of your customers. Wow, that’s an eye-opener! This means your business can survive (at least break even) just by cross-selling or up-selling to your existing customers. You almost don’t need to onboard new customers.

Are you thinking – this doesn’t concern me, I have a great product and my customers will never abandon me? Then, there’s another bitter pill you’ll have to swallow: no matter how good your product or service is, your customers might leave if they feel neglected. This is why many top-notch products and companies shut down. They just don’t work hard enough to build customer loyalty. In fact, a good 68% of customers say a company’s uncaring or impersonal attitude is a relationship-killer.

The graphic below will prove our point:

So putting things in perspective, we have compiled battle-tested techniques for retention of product customers.

1) Deliver Quality Products: The key to gaining repeat business is delivering top quality products. Nothing works as well as a product that wows with its features. Even if your product is marked higher than competitors, it will reign supreme if it’s a cut above the rest.

Let’s illustrate with an example: Two doorstep service providers, Urban Clap and Yes Madame. Both offer at-home salon services at competitive prices. Urban clap is priced higher than Yes Madame. Yet, it is market share is bigger. Why? The differentiator is service quality. UC technicians are better trained, use branded products, and are punctual and courteous. Granted, UC has the first-mover advantage, but it’s managed to keep up and even beat competition just because of its killer services. Although, the great marketing helps, but remember, even the most radical marketer can’t sell a product that sucks. Do ample market research when creating your product strategy. Understand what your audience needs. Have a long vision plus short-term goals. Never compromise on quality when faced with time or budget constraints. This is a non-negotiable area that every successful product company excels at.

2) Nurture Customer Relations: KPMG in their study found customer retention to be the biggest revenue driver for companies. The secret that many product companies don’t know is that loyal customers are their best promoters. Satisfied customers become brand ambassadors of a company. They campaign unknowingly about the superb experience they’ve had with a company or product they’re using. Their genuine, first-hand account is a marketing billboard in itself. You don’t need to hire expensive influencers for generating brand awareness or leads for yourself. Your happy customers are doing it for you. So, provide excellent customer service. Reward your return customers with gated offers, discounts, and resources. Treat them well and they’ll treat you better. Keep in touch with them via email, newsletters, and your website. Feature their stories on your social apps and website. Make them your family. Involve them in your journey and they will stay till the very end. A practical way to do this is to draw a list of customers who buy from you regularly. Reach out to them via exclusive offers and make them feel special. Another good tip: List out subscribers to your newsletter. These are people who show an active interest in your work but haven’t purchased anything yet. To make them jump boat, send a first-time promotion offer or discounted service/product. 

3) Lend a Personal Touch: Personalize all your emails and offers. Rid the assembly line approach of sending mass emails. An Ecoconsultancy survey has proved personalized offers, based on a user’s purchase history and preference, can surge your ROI to the sky. This infographic compares the business returns of companies using personalization vs. those that don’t.

4) Listen to Your Customers: Some product companies just never stop selling. Every effort of theirs is geared towards the cash register. This is hardly effective as customers, existing or new, don’t want to be taken for a ride. You’ll have to give them something in return. One of the best ways to make the relationship mutually beneficial is to incorporate their feedback into your future offerings. Don’t send lengthy questionnaires to customers asking them for their opinion or experience with your product. Keep it short and simple. Encourage specific, precise feedback regarding what they liked or didn’t like. Try to collate points and factor them into your product strategy. Do keep respondents in the loop, reassuring that their feedback isn’t ignored. When you value your customers’ opinions, they become stakeholders in your business.  Your product becomes more aligned to market needs. Your ROI improves and so does your customer satisfaction index.5-Effective-Ways-of-Retaining-Product-Customers_3 Source

5) Use a CRM: A CRM system is a handy way to keep track of how customers interact with your product. Draw up metrics of customer inquiries. What bottlenecks are customers facing with your service or product? Are they content with the after-sales service you’re giving? Do you need to improve in some areas? Deeply inspect issues that are reported by the majority of your customers. These have to be resolved on a priority basis. CRM also gives you a sneak peek into how well your sales or customer service staff are working. Disgruntled employees and lackadaisical post-sales staff can annoy a customer big time. This is a serious red flag for any organization and should be attended to immediately.

Wrap Up

By now, you must have grasped the impact customer retention can have on the sales and success of your business. Work your magic on your current customers. They are the big fish that’ll act as bait for the other fish in the pond.

How to Manage Distributed Product Development Teams

An important tenet of the Agile Manifesto is that successful product teams must collaborate daily from a shared co-location. But, we wish to challenge this notion. Remote product teams (spanning continents, cultures, and time zones) are very much the need of the hour. And, with sophisticated collaborative tools available, distributed teams can be as productive as co-located ones. A changed mindset from product managers and some flexibility from team members is the only requisite.
