Meetup report: February 2019 Meetup: Build with Serverless

Summary of February 2019 Meetup focusing on Serverless with AWS Amplify

Build with Serverless started with a warm welcome by Jeevan Dongre, AWS Community Hero and Lead - AWS User Group Bengaluru and introduced our speaker of the day, Prashanth HN co-founder of


Talk started with the question: “What is Serverless Architecture ?”

A serverless architecture is a way to build and run applications and services without having to manage infrastructure. By using a serverless architecture, developers can focus on their core product instead of worrying about managing and operating servers or runtimes, either in the cloud or on-premises. Serverless has some benefits, for instance:

  • Flexible Scaling_ Automated High Availability_ No Server/Infrastructure Management* Pay for Value AWS provides a set of fully managed services that one can use to build and run serverless applications. Serverless applications don’t require provisioning, maintaining and administering servers for backend components such as compute, databases, storage, stream processing, message queuing and more. Here are some examples of Serverless managed services offered by AWS:

Then Speaker talked about: “What is AWS Amplify?”

AWS Amplify is an open source JavaScript library provided by Amazon Web Services (AWS) that enables developers to build applications with cloud services on web or mobile platforms. It is designed to be an open and pluggable with other back-end components and services. It is designed to give a declarative interface to client developers looking to perform common actions using cloud services in a scalable and secure manner. The AWS Amplify library modules are broken down into categories (Auth, Analytics, Storage, APIs, Caching) to quickly add features such as User Sign Up/Sign In, MFA, tracking or metric analytics, content management or Serverless API integration.

  • Amplify CLI_ Amplify Console_ Amplify JS Library The AWS Amplify CLI helps you set up an AWS IAM user, set up an AWS profile on your local system and then initialize Amplify powered apps with all your defined configurations
    \ $ amplify configure (Configure CLI) The amplify init command is a one-time initialization step for your Amplify powered cloud app. \ $ amplify init ( Initialization ) Amplify provides a set of comprehensive library for building sophisticated cloud-powered apps:

And it’s time for a demo. Yes, it was a live demo by Prashanth starting from very scratch. Demo includes:

  • How to install Amplify CLI?
  • How to develop an application with Amplify?
  • How Amplify automatically creates resources inside AWS account?
  • And finally how to deploy an application with Amplify Console?

Demo was started with a simple calorie counter application which was purely using React local state with no auth & no data persistence. Presenter started adding capabilities to application one by one to show how easy and powerful it is to build apps using Amplify.

In the first step app was added with Authentication which also exposed inbuilt components & authentication flows amplify react library provides. Next, CRUD API got added to application and the app started creating and reading records from DynamoDB through API. In the last step of development process, presenter showed how one can store & read custom user attributes on Cognito.

After adding all capabilities the app was fully functional & it was time to ship it to the internet. Presenter used Amplify dashboard to setup CI/CD pipeline for the project and explained how amplify can not only deploy frontend but also deploy all backend changes. The build was successful and the app was ready with a amplify link for others to check out.

If you find AWS Amplify exciting and want to get start with it, below are some reference links which helps you in getting start:

On the whole it was a wonderful demo where Amplify, Cognito & Serverless were absolutely simplified. The most frequently asked questions from the attendees were "Show me the console, Did Amplify do everything for you ?"
