High Availability Installation
Before installing CA Identity Manager, consider the goals for your implementation. For example, one goal could be a resilient implementation that consistently provides good performance. Another goal could be scalability.
A high-availability implementation provides the following features:
- Failover—Switches to another system automatically if the primary system fails or is temporarily offline for any reason
- Load balancing—Distributes processing and communications activity evenly across a computer network so that performance remains good and no single device is overwhelmed
- Various deployment tiers that provide the flexibility to serve dynamic business requirements
To provide these high-availability features, the following implementation options exist:
- The Identity Manager Server can be installed on an application server cluster to allow failover to any of the node in the cluster, providing uninterrupted access to users. The application server can be a 64-bit format, which provides better performance than a 32-bit application server.
- The Provisioning Server uses a CA Directory router to route traffic to a Provisioning Directory
- CA Identity Manager includes connector servers that you configure per-directory or per-managed systems. Installing multiple connector servers increases resilience. Each connector server is also an LDAP server, similar to the Provisioning Server.
