A company's new mobile app uses Amazon API Gateway. As the development team completes a new release of its APIs, a developer must safely and transparently roll out the API change.

What is the SIMPLEST solution for the developer to use for rolling out the new API version to a limited number of users through API Gateway?

  • A. Create a new API in API Gateway. Direct a portion of the traffic to the new API using an Amazon Route 53 weighted routing policy.
  • B. Validate the new API version and promote it to production during the window of lowest expected utilization.
  • C. Implement an Amazon CloudWatch alarm to trigger a rollback if the observed HTTP 500 status code rate exceeds a predetermined threshold.
  • D. Use the canary release deployment option in API Gateway. Direct a percentage of the API traffic using the canarySettings setting.

Selected Answer: D
A) Eliminated - creating a new API in API Gateway requires managing two separate APIs, which adds unnecessary complexity. B) Eliminated - This is a direct cutover approach, not a gradual rollout to a limited number of users. If issues arise, all users are impacted, which is not safe or transparent. C) Eliminated - It is not relevant to the question's requirement D) Correct - It allows gradual exposure of the new API version to a subset of users, minimizing risk.

Selected Answer: D
Canary deployments allow you to divert a percentage of your API traffic to a new API version, enabling you to test how the new version will perform under real-world conditions without fully replacing the previous version. This is especially useful for reducing the risk associated with deploying new versions.
