CR2Web Cluster
-
This module is linked to the load balancer.

CR2Web Cluster follows the round-robin policy to select the connected session pool.
CR2Web Session Pool

-
It oversees all CR2 application instances initiated and supervised within this layer.

This module is lightweight and can seamlessly connect to multiple clusters.
CR2Web Admin Console
