Evaluating Benefits and Trade-Offs

Benefits

• System failover provides continuous OpenSSO Enterprise service when hardware or software fails.

• Session failover ensures uninterrupted transactions and no user data loss during system failure.

• In most cases, user does not have to re-authenticate after system recovery.

• Increased transaction throughput through load sharing.

• Increased security because Policy Agents never interact directly with OpenSSO Enterprise servers.

Trade-Offs

• Slight impact to performance when OpenSSO Enterprise is configured for session failover.

• Firewall must be open between OpenSSO Enterprise communicating components.
