The Gold MAA reference architecture Remote Standby pattern includes a remote synchronized copy of the production database (Standby Database) using Oracle Active Data Guard to eliminate single point of failure. The active standby database provides a high level of protection from unplanned outages and reduces downtime for planned maintenance activities, such as database upgrades. The most notable attribute is that the standby provides low RTO (recovery time) and RPO (data loss potential) in the case of a disaster such as a database, cluster, or site failure.
