Serverless Backend for Frontend on AWS
summary
Shows how to implement Backends for Frontends on AWS using concrete services and patterns and includes a live demo of developer setup, testing and deployment. Builds a REST BFF with API Gateway + Lambda + DynamoDB, ingests upstream data via EventBridge / webhooks / scheduler, stores secrets in Secrets Manager and authenticates with Cognito. Demonstrates a booking saga with compensating actions using Step Functions for orchestration, and adds observability with CloudWatch and X Ray so the design is deployable and traceable.
