  • Topic 1 Question 87

    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?

    • 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.

    • Validate the new API version and promote it to production during the window of lowest expected utilization.

    • Implement an Amazon CloudWatch alarm to trigger a rollback if the observed HTTP 500 status code rate exceeds a predetermined threshold.

    • Use the canary release deployment option in API Gateway. Direct a percentage of the API traffic using the canarySettings setting.
