Deployment Specification Instance   A deployment specification instance is a distinct instance of a deployment specification. While the deployment specification specifies a set of properties that govern the way an artifact will execute on a node, a deployment specification instance gives these properties actual values. Typically a deployment specification specifies values of the properties for a particular type of execution environment. It is itself a type of artifact instance and is owned by a deployment.

Explanation

A deployment specification instance is used to give values to a number of properties that specify how a deployed artifact will execute on the node on which it is deployed. While a deployment specification specifies the properties of the artifact deployment, a deployment specification instance is an actual example of the deployment specification with values being set for the properties. It is a mechanism to parameterize the deployment of an artifact instance, allowing a number of aspects of the way the artifact instance will execute to be separated from the artifact instance itself. This separation has become a standard practice in many hardware and software environments.
