CASE STUDY: RetailMart
Overview: Global e-commerce, 5,000 employees. Legacy monolith on VMware, 20TB Oracle DB on-prem.
Business: Modernize to microservices, 100% uptime during Black Friday (10x traffic), real-time inventory sync, exit data center in 2 years.
Executives:
- CEO: "Innovate faster to beat online-only competitors."
- CFO: "End hardware CAPEX. Move to pure OPEX."
- CTO: "Break monolith safely. Zero downtime during transition."
Tech: Migrate off Oracle to open-source, containerize, secure hybrid connectivity during transition, automated scaling.
Constraints: Zero downtime for storefront, heavy reliance on Oracle stored procedures, all hybrid traffic must be private/encrypted.
Which migration approach should you recommend to safely break down the monolith with zero downtime?

Answer options:
Use Jenkins on Compute Engine to build images, store them in Cloud Storage, and deploy via bash scripts.
Use Cloud Build to create container images, store them in Artifact Registry, and use Binary Authorization to ensure only signed images are deployed to GKE.
Use Cloud Source Repositories to build images and deploy directly to Cloud Run.
Use GitHub Actions to build images and push them to Docker Hub, then pull from GKE.
