Standalone Deployment : A deployment that has a single Cisco ISE node is called a standalone deployment. This node runs the Administration, Policy Service, and Monitoring personas. This deployment is suitable for Small production setup’s or labs. If we are deploying ISE in standalone mode then we will not have redundancy.
Hybrid Deployment : A deployment that has multiple ISE nodes wherein PAN and MNT will be on enabled on a single node. This node will run PAN and MNT along with this we ca dedicated PSN’s in the deployment.
Distributed Deployment : A deployment that has multiple ISE nodes wherein we have a separate node for each persona. The distributed deployment consists of one Primary Administration ISE node, Secondary admin nodes, Primary Monitoring node, Secondary Monitoring node followed by PSN(Policy Service Node).
Each node can perform one or multiple services. ISE implementation is typically deployed in a distributed manner with individual services run on dedicated ISE nodes.
