What is Warm Standby Mode?
 
How Do I Set Up Data Center in Warm Standby Mode?
In the Warm Standby mode, there are only two data centers. The primary data center is up and running, and in the secondary data center, only API Data Store is up and running, whereas API Gateway is in a shutdown state and is turned on only during disaster recovery. The secondary data center is regularly backed up with primary data center's data. On failure of the primary data center, the secondary data center replaces the primary data center. As part of disaster recovery procedure, perform the following steps in the secondary data center:
*Bring up API Gateway.
*Reconfigure the load balancer to redirect the traffic to the standby data center.
The RPO and RTO for warm standby mode is less when compared to cold standby mode.
