Question

Your team runs a payment API on GKE and uses Google Cloud Deploy for releases to production. Compliance requires that a fully provisioned copy of the new version receive synthetic transaction tests before any live customer traffic is shifted, and that traffic can be reverted to the previous version within seconds if the tests reveal a problem. Which deployment strategy configuration in Cloud Deploy best meets these requirements?

Accepted Answer

Configure a blue-green strategy that fully deploys the new version to a separate pool, runs a verification phase against it, and only then routes 100% of production traffic to the new version.

Answer

Configure a canary strategy with 5%, 25%, and 100% traffic phases and a verification step at each phase.

Answer

Use the default rolling update strategy of the GKE Deployment and add a post-deploy verification hook in the Cloud Deploy pipeline.

Answer

Configure a canary strategy with a single 0% phase so no traffic is served during verification, then jump to 100%.
