Release Notes for Cisco Identity Services Engine, Release 1.1
OL-25539-01
  Introduction
Introduction
The Cisco ISE platform is a comprehensive, next-generation, contextually-based access control solution. 
Cisco ISE offers authenticated network access, profiling, posture, guest management, and security group 
access services along with monitoring, reporting, and troubleshooting capabilities on a single physical 
or virtual appliance. Cisco ISE ships on a range of physical appliances with different performance 
characterization and also allows the addition of more appliances to a deployment for performance, scale, 
and resiliency. Cisco ISE has a highly available and scalable architecture that supports standalone and 
distributed deployments, but with centralized configuration and management. Cisco ISE also allows for 
configuration and management of distinct Cisco ISE personas and services. This feature gives you the 
ability to create and apply Cisco ISE services where they are needed in the network, but still operate the 
Cisco ISE deployment as a complete and coordinated system.
Node Types, Personas, Roles, and Services
Cisco ISE provides a highly available and scalable architecture that supports both standalone and 
distributed deployments. In a distributed environment, you configure one primary Administration node 
and the rest are secondary nodes. The topics in this section provide information about Cisco ISE 
terminology, supported node types, distributed deployment, and the basic architecture.
Cisco ISE Deployment Terminology
 describes some of the common terms used in Cisco ISE deployment scenarios.

Term
Description
Service
A service is a specific feature that a persona provides such as network 
access, profiler, posture, security group access, and monitoring.
Node
A node is an individual instance that runs the Cisco ISE software. Cisco ISE 
is available as an appliance and also as a software that can be run on a 
VMware server. Each instance (either running on a Cisco ISE appliance or 
on a VMware server) that runs the Cisco ISE software is called a node.
Node type
A node can be of two types: ISE node and Inline Posture node. The node 
type and persona determine the type of functionality provided by that node.
Persona
The persona or personas of a node determine the services provided by a 
node. A Cisco ISE node can assume any or all of the following personas: 
Administration, Policy Service, and Monitoring.
Role
Determines if a node is a standalone, primary, or secondary node. Applies 
only to Administration and Monitoring nodes.
