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 WebSphere® ESB for z/OS® applications. A stand-alone configuration provides a framework for a quick start or development environment and if you are configuring for a small environment you may find that a single server topology is all you need to meet you requirements. However, you are probably more likely to use a network deployment configuration because it can administer application servers that may be dispersed among multiple sysplexes in a network environment. A network deployment configuration is intended to support multiple application servers which can be clustered to provide high availability and reliability.
