AWS Lambda is a serverless, event-driven compute service that runs code for virtually any application or back-end service without provisioning or managing servers.

In this lab, we’ll learn to host a simple serverless application on AWS Lambda and access it through an API Gateway endpoint.

Lab tasks

Create an S3 bucket.
Upload the code archive to the bucket.
Create a Lambda function.
Create an API Gateway.
Access the application.
Clean up.
