Google Cloud

If you're running an application in the cloud, you need it to trust that it's available whenever you need it. Cloud SQL for PostgreSQL’s high availability (HA) configuration helps ensure your database workloads are fault-tolerant. This guide explores how Cloud SQL can optimize and boost a typical PostgreSQL HA technology stack through continuous health checks, synchronous data replication across zones, and automatic failover and scalability.

This guide covers:

  • An overview of high availability
  • General components of a highly-available PostgreSQL cluster
  • Self-managed options for the replication layer
  • Cluster management in Cloud SQL
