About This Architecture

Serverless REST API using API Gateway, Lambda functions, and DynamoDB with global replication for multi-region resilience. Cognito User Pool secures user authentication while four Lambda functions (128MB each) handle Create, Read, Update, and Delete operations against a DynamoDB Items Table. IAM Roles enforce least-privilege access, and CloudWatch monitors Lambda execution for operational visibility. Fork this diagram to customize function memory, add caching layers, or extend to additional AWS regions.

How do I design a production-ready serverless REST API on AWS with multi-region data replication and user authentication?

This diagram shows a complete serverless REST API using API Gateway to route requests to four Lambda functions (Create, Get, Update, Delete) backed by DynamoDB with global table replication for multi-region resilience. Cognito User Pool secures authentication, IAM Roles enforce least-privilege access, and CloudWatch provides operational monitoring.
