What are Serverless Apps and How to deploy one on AWS

In this video, I talk about Serverless apps and how to deploy a serverless app on the AWS platform. Serverless apps enables you to directly deploy your backend code in the form of functions that get triggered for a specified event on your app, without having to build, configure, and maintain your own server. You can also use other AWS services like AWS DynamoDB from your serverless backend. We also use Amazon Cognito which is a user authentication service that offers access-control to our website. Then, we use the Amazon API Gateway to create an end-point and link it to a serverless function that is written on AWS Lambda. All the static files of the website are hosted on AWS Amplify.

This video follows a hands-on workshop that is officially organized by AWS, check it out here: https://aws.amazon.com/getting-started/hands-on/build-serverless-web-app-lambda-apigateway-s3-dynamodb-cognito/
