All Components in Multiple Data Centers
You extend the SOA Security Manager environment by deploying multiple data centers. The following factors can influence your decision to implement multiple data centers:
- The network infrastructure
- The location of applications
- The location of users
The following diagram illustrates:
- Applications in multiple data centers
- Each data center using its own policy store. Data center one contains the primary policy store. Data center two contains the replicated version, as detailed by the dotted line.
Note: Every Policy Server in the deployment must share a common view into the same policy store. For more information about policy store redundancy, see Policy Server to Policy Store Communication.
- Each data center using its own master/consumer user stores.
Important! For more information about multi–mastered LDAP user store support limitations, see the Policy Server Release Notes.
- A centralized replicated session store to enable single sign–on between all applications.
