Your company is migrating all legacy applications to Google Cloud. All on-premises applications are using legacy Oracle 12c databases with Oracle Real Application Cluster (RAC) for high availability (HA) and Oracle Data Guard for disaster recovery. You need a solution that requires minimal code changes, provides the same high availability you have today on-premises, and supports a low latency network for migrated legacy applications. What should you do?

Question

Accepted Answer

D. Migrate the databases to Bare Metal Solution for Oracle. Bare Metal Solution provides dedicated physical servers certified for Oracle Database, allowing Oracle RAC and Oracle Data Guard to run exactly as they do on-premises. This satisfies the requirement for minimal code changes, equivalent high availability, and low-latency network access for co-located legacy applications without re-platforming to a different database engine.

Answer

A. Migrate the databases to Cloud Spanner. Cloud Spanner uses a different data model and API, requiring substantial application code changes to migrate from Oracle.

Answer

B. Migrate the databases to Cloud SQL, and enable a standby database. Cloud SQL does not support Oracle as a database engine, so migrating Oracle databases to Cloud SQL would require a full engine migration and significant code changes.

Answer

C. Migrate the databases to Compute Engine using regional persistent disks. Running Oracle on Compute Engine with regional persistent disks does not natively support Oracle RAC clustering, which requires specific networking and storage configurations only available on bare metal hardware.
