As APIs grow and change, versioning becomes crucial for maintaining stability and backward compatibility for users. Without a clear versioning strategy, even minor updates can disrupt existing integrations and lead to inconsistent behavior across applications. Amazon API Gateway is a fully managed service for building, publishing, and maintaining APIs at scale. It provides several methods for implementing versioning. One of the simplest and most widely used approaches is path-based API versioning.
In this Challenge Cloud Lab, you’ll be tested on your ability to build a versioned API using Amazon API Gateway. You’ll be evaluated on creating a Lambda function and then developing two versions of the function to simulate backend updates, demonstrating your skill in serving multiple isolated API versions under one consistent domain.
A high-level architecture diagram for this Challenge Cloud Lab is given below:
