Secure API Manager stores all configuration information for the system in the Database Service component. It is important that you cluster the Database Service component to ensure high availability. If one node in a cluster goes down, it is a simple process to redeploy that node as long as there is one Database Service node up and running. For more information, see Using High Availability and Load Balancing with Secure API Manager.
It is also very important that you create and implement a backup plan for the Database Service component. If a disaster occurs to your entire system, you can restore the Database Service component and then redeploy the other components to restore your system.
