🚀 Build & Automate Serverless APIs on AWS
In this video, we’ll walk through how to create a serverless API from scratch using Amazon API Gateway, AWS Lambda, and DynamoDB — first manually, then automated with AWS CloudFormation!

You’ll learn how to:
✅ Create an API Gateway endpoint to invoke a Lambda function
✅ Build a Lambda function to interact with DynamoDB
✅ Test the API using Postman
✅ Deploy and manage the same setup automatically using CloudFormation
✅ Help Compare manual setup vs. Infrastructure as Code (IaC) for better efficiency

Whether you’re a DevOps engineer, backend developer, or AWS learner looking to upskill in serverless architecture, this hands-on session is for you.
