Regional endpoints (REP) are now generally available (GA) for the Cloud SQL for PostgreSQL Admin API.

Regional endpoints (REP) are now generally available (GA) for the Cloud SQL for PostgreSQL Admin API.

Regional endpoints let you interact with Cloud SQL for PostgreSQL instances using regionalized URLs (such as sqladmin.{region}.rep.googleapis.com) rather than through a single global endpoint.

Regional endpoints provide regional frontend and load balancing infrastructure that improves data residency by keeping network traffic within the same region as the instance. This reduces the instance's dependency on global frontend infrastructure.

Regional endpoints have strong regional isolation, so the failure of a load balancer or frontend in one region doesn't affect any other region. Regional service load balancers have a separate, regionally isolated control plane.

Regional endpoints are designed to meet stringent data residency and sovereignty standards, such as ITAR and Assured Workloads Regions, ensuring data in transit remains within the committed region.

Certificate management and TLS termination occurs within each region, on the regional load balancer, so data remains encrypted until it reaches its destination region and stays within that region while being processed there.
