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 Wheelsbox.com.
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:

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