Modern cloud architectures often need to support different user experiences behind a single application endpoint, while remaining secure, scalable, and easy to evolve. AWS provides managed services that make this possible without relying on traditional servers or complex routing logic.
In this Cloud Lab, you’ll explore how AWS Lambda, Application Load Balancers (ALB), and Amazon DynamoDB can be combined to implement this pattern. Lambda enables serverless backend logic, DynamoDB provides a scalable data store, and the ALB acts as an intelligent entry point that can inspect incoming requests and route them dynamically.
By the end of this Cloud Lab, you’ll understand how HTTP header–based routing and AWS Lambda versioning can be used to expose different backend behavior through a single endpoint. This approach enables applications to introduce advanced features, manage access levels, and evolve functionality over time, without duplicating infrastructure or changing client-facing URLs.
The following is the high-level architecture diagram of the final infrastructure that you will build in this Cloud Lab:
