The following figure illustrates the architecture of a Dell Telecom Infrastructure Automation Suite HA cluster:
With high availability (HA), the Dell Telecom Infrastructure Automation Suite cloud is deployed on a three-node HA cluster to provide a highly reliable management across the cluster.
The primary control plane (CP1) node is deployed on the first node. Two HA nodes (CP2 and CP3) function as a redundant pair for HA failover and must be reachable from the main control plane node. All nodes are active.
