High-Performance and High-Reliability System
Interstage Single Sign-on supports high-performance and high-reliability systems such as client
certificate verification, high-speed SSL communication, load balancing, and increased availability.
Load Balancing
When the authentication requests from users converge on the authentication server, the load on the
server is also increased. The load can be balanced by adding an authentication server.
Also, the authentication processing on the repository server can be distributed to two repository servers,
repository server (update system) and repository server (reference system) in order to balance the load
of authentication processing on the repository server.
To distribute authentication processing to the repository server (update system) and repository server
(reference system), select, on the Interstage Management Console, [System] > [Security] > [Single
Sign-on] > [Authentication infrastructure] > [Authentication server] > [Settings] > [Detailed Settings
[Show]].
Then, specify the repository server (update system) and repository server (reference system) for
[Communication Settings with Repository server] and [Communication Settings with repository Server
(reference system)].
For details about the configurations on the Interstage Management Console, refer to the Operator’s
Guide.
It is recommended to install one repository server (update system) and multiple repository servers
(reference systems) to balance the load of authentication processing on the repository servers.
