Hot Standby

Category: infrastructure

A backup database that is constantly kept in sync with the primary to allow for near-instant failover.

Hot Standby is the "live clone." Every transaction on the primary database is immediately written to the clone. If the primary dies, the clone takes over without losing a single transaction. It is the gold standard for high-availability database architectures.

Common Examples

• Our database architecture includes a hot standby node in a separate availability zone, ensuring seamless failover during major data center events.
• The primary difference between standard replication and a hot standby is the level of automatic failover integration and data sync fidelity.
