In a large SailPoint IdentityIQ implementation, how many UI servers are typically required?

In a large SailPoint IdentityIQ implementation, the recommendation of having two UI servers typically arises from the need for load balancing and redundancy. With two UI servers, organizations can ensure that if one server goes down or becomes unavailable, the other can take over, providing continuous access to the IdentityIQ user interface without interruptions. This setup also allows for better management of user sessions, as the load can be evenly distributed between the two servers, thus enhancing performance and responsiveness during peak usage times.

Furthermore, having multiple UI servers can facilitate maintenance and updates. System administrators can perform updates on one server while keeping the other server operational, ensuring that users remain unaffected during routine maintenance activities. In scenarios where high availability and performance are critical, a configuration with two UI servers is often the baseline recommended practice.
