Architecting a vRealize Operations Management Solution : Performance and Scalability : 8.2 Load Balancing
   
8.2 Load Balancing
The vRealize Operations Manager user interfaces can be accessed from any full node. VMware recommends a load balancer for even distribution of the user interface traffic and load.
The maximum number of concurrent user connections per node is four (4), based on a worst-case scenario. The load per user varies depending how many objects the user is permitted to access (in particular, if the user is running views or reports against large sets of metrics over a long time).
Design Considerations
If vRealize Operations Manager is to be configured as a cluster, use an external load balancer to distribute the load across the cluster.
