The MAA Silver reference architecture is designed for databases that can't afford to wait for a cold restart or a restore from backup, should there be an unrecoverable database instance or server failure. MAA Silver may be suitable for production applications that are business critical and need to reduce downtime for local failures and the most common planned maintenance activities.

The MAA Silver architecture patterns are built on the foundation of the MAA Bronze architecture, and add either Oracle Real Application Clusters (Oracle RAC) active-active clustering or a local Oracle Data Guard standby database for minimal or zero downtime in the event of database instance or server failure, as well as zero database downtime for the most common planned maintenance events.

Just like in the MAA Bronze architecture, Recovery Manager (RMAN) provides database-optimized backups to restore availability should there be a complete cluster outage or disaster.
