This section introduces geo-replication, illustrates the various deployment scenarios, and explains how to configure geo-replication and mirroring.
14.1. About Geo-replication
Geo-replication provides a distributed, continuous, asynchronous, and incremental replication service from one site to another over Local Area Networks (LANs), Wide Area Networks (WANs), and the Internet.
Geo-replication uses a master–slave model, where replication and mirroring occurs between the following partners:
