All Components in Multiple Data Centers

You extend the SiteMinder 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.
