High Availability for PostgreSQL (original) (raw)

The HA infrastructure is built within a single data center on your local node. It is intended to keep the database available should the primary node go down, either from an automatic failover or planned switchover.

The infrastructure features two disaster recovery sites, which ensures high availability and keeps your applications up and running. Based on tightly coupled database clusters spread across data centers and availability zones, it offers an HA level of 99.999% when using synchronous streaming replication, having the same hardware configuration in all nodes, and a fast internode connection.
