Replication

Definitions

1. The process of copying and maintaining data across multiple database instances or nodes so that every replica holds the same information, improving availability and fault tolerance.

   In plain English: Keeping identical copies of your data on multiple servers so that if one goes down, the others still have everything.

   Example: "We set up PostgreSQL streaming replication to a hot standby in another AZ."
