RDS Multi AZ (Disaster Recovery)

  • SYNC replication!!! So all changes on the primary are replicated immediately by standby too

  • Used for disaster recovery

  • One DNS name and AUTOMATIC FAILOVER. If any failure happens on the primary database standby database takes control and is promoted to the master database

  • Increase availability

  • No manual intervention in apps

  • Not used for scaling. It means the standby database is not used for reading and writing by apps until any problem occurs on the master primary database

  • The read replicas can be set up as Multi-AZ for recovery disaster

  • FROM SINGLE AZ TO MULTI AZ CAN BE SET UP BY MODIFYING PRIMARY DB SO ZERO DOWNTIME IS POSSIBLE

SINGLE TO MULTI AZ STEPS

Snapshot is taken from the primary db AZ then it is recovered from the other AZ.
