GCP Professional Cloud Architect Practice Question

A retail company is decomposing its on-premises monolithic e-commerce application into containerized microservices that will run on multi-region GKE clusters. Development teams aim to ship new capabilities every week, but their current software development life cycle is a quarterly, waterfall process with manual QA gates. As the cloud architect, which change to the SDLC will most effectively exploit the new cloud-native architecture while maintaining release quality?

  • Keep the existing waterfall SDLC but migrate the staging and production environments to managed instance groups on Google Cloud for better scalability.

  • Replace pre-production testing with chaos engineering experiments executed only in production to detect issues after deployment.

  • Adopt trunk-based development with automated CI pipelines that build, test, and publish versioned container images to Artifact Registry for every commit, enabling continuous delivery of each microservice.

  • Introduce two-week code-freeze periods before each sprint to coordinate microservice dependencies and perform manual integration testing.
