说明与用途

将 PostgreSQL 和 ML 工作负载从 AWS 迁移到 GCP，停机时间最小化。

问题

The team needed to move their PostgreSQL and ML workloads from AWS to GCP while keeping downtime to a minimum.

结果

The migration completed with less than 30 minutes of downtime, improved scalability, and reduced operational overhead.

工作流

• 1. Set up a GCP project and enable Cloud SQL and Compute Engine APIs.
• 2. Create a Cloud SQL instance with PostgreSQL and install pgvector and PostgreSQL ML extensions.
• 3. Export the AWS database using pg_dump and import into Cloud SQL.
• 4. Configure network connectivity and firewall rules between AWS and GCP.
• 5. Update application connection strings to point to the new Cloud SQL instance.
• 6. Perform a test migration and validate data integrity and application functionality.
• 7. Switch traffic to GCP during a low-usage window, monitoring performance and logs.
• 8. Decommission AWS resources after successful cutover.
