With replication, organizations can extend the database and server to minimize outages. One replication method, active-active replication
(also known as peer-to-peer, master-to-master, active-active, or multi-active server replication), offers the most promise. Active-active replication is a horizontal scaling of the application over multiple servers that allows propagation of changes to more than one server. If everything is done properly, end users will not see any outages from the application. This white paper discusses the key considerations to keep in mind when using active-active replication to ensure high availability.
