Differences between stand-alone and ND configurations

A stand-alone application server cell, also known as a base application server node, is the simplest configuration you can use to deploy and run IBM BPM for z/OS applications. A ND configuration is intended to support multiple application servers, which can be clustered to provide high availability and reliability.

A stand-alone configuration provides a framework for a quick start or development environment, and if you are configuring for a small environment you might find that a single server topology is all you need to meet your requirements. However, you are probably more likely to use an ND configuration because it can administer application servers that can be dispersed among multiple sysplexes in a network environment.
The main differences between a stand-alone and an ND configuration are as follows:

Stand-alone and ND configuration differences
Stand-alone configuration Network deployment configuration
A minimum of four address spaces are allocated for the following processes:

Location service daemon
Controller
Servant
Control region adjunct

The maximum amount of address spaces is limited only by resources.
A minimum of seven address spaces are allocated for the following processes:

Location service daemon
Application server controller
Application server servant
Application server control region adjunct
Deployment manager controller
Deployment manager servant
Node agent

The maximum amount of address spaces is limited only by resources.
Each server node is in a separate administrative domain. All nodes in the cell are in the same administrative domain.
You can start and stop servers independently. Each server has an independent, unshared JNDI namespace. You can start and stop servers independently; however, the JNDI namespace is shared among all servers in the cell.
Multiple servants are allowed. Multiple servants are allowed.
Clustering is not available. Clustering is available.
