Hi James,

MID Server clusters enable multiple MID Servers with the appropriate capabilities to be grouped together for load balancing and fail-over protection. 

For more details regarding MID Server Cluster refer below link:

Kindly find below link for Configuration Mid-Server Cluster:

Load Balancing:

Discovery can collect data about network routers, switches, and applications.

Discovery supports data collection from the following applications and hardware:
  • A10
  • Apache mod_jk and Apache mod_proxy
  • Big-IP F5 Traffic Manager
  • Cisco
  • Citrix NetScaler
  • HAProxy
  • NGINX
  • Alteon
  • ACE
  • Radware

For more info regarding Load Balancing refer below link:

Please after going through this mark it as helpful or correct.

 

Thanks,

Hello James.

MID Server clusters are managed by a business rule called MID Server Cluster Management, which checks to see if the MID Server assigned to a job in the ECC Queue belongs to a cluster. 

 

If the cluster business rule determines that a MID Server is part of a load balancing cluster, the application using the MID Server automatically balances the work between the MID Servers in that cluster. It is good practice to put MID Servers with the same capabilities in a load balancing cluster.
