Load balancers distribute connections among servers in high availability (HA) deployments.
The advantages of using a load balancer in front of the VMware Aria Operations cluster:
Utilizing a load balancer ensures that the deployed cluster is properly balanced for performance of UI traffic.
The cluster allows all nodes in the cluster to equally participate in the handling of UI sessions and traffic.
The provides high availability if any admin or data node fails, by directing UI traffic only to serving nodes in the cluster.
It provides simpler access for the users. Instead of accessing each node individually the user only needs one URL to access the entire cluster and not be concerned with which node is available.
The system administrator backs up the load balancers regularly at the same time as other components.
Follow your site policy for backing up load balancers, keeping in mind the preservation of network topology and VMware Aria Operations backup planning.
