How do you scale vManage in a Cisco SD‑WAN deployment?

To scale vManage for increased capacity and high availability in a Cisco SD-WAN deployment, you deploy multiple vManage controllers in a cluster. This distributed architecture allows for load balancing and ensures that if one vManage instance fails, others in the cluster can continue to operate, maintaining management plane functionality. Increasing the bandwidth of the WAN link to a single vManage might improve connectivity but doesn't address processing capacity or redundancy. Increasing licensing on vManage enables more devices to be managed but does not scale the vManage platform itself. Deploying more than one vManage on different physical servers without clustering them would result in separate, uncoordinated instances, not a scalable or highly available solution.
