1. A method of deploying an enterprise application, said method comprising: including, in a set of instructions that is tangibly embodied on a non-transitory memory medium and that defines an instance of said enterprise application as executable by a processor on a computer, a mechanism allowing said enterprise application to autonomously exercise, on each node receiving the enterprise application instance, a node differentiation/specialization function as related to the enterprise application, each said instance comprising a look-alike software module as a single set of instructions having a plurality of modules that define an execution of a plurality of different tasks possible for execution by said enterprise application, including a task that each node receiving an instance of said enterprise application can selectively configure itself to execute a different task or combination of tasks of said plurality of different tasks, said node differentiation referring to differences in nodes of a plurality of nodes, even though all the nodes are separately executing respective instances of said enterprise application, said specialization referring to task specializations relative to the enterprise application, meaning that the look-alike software modules can be selectively configured to define a different task or combination of tasks of said enterprise application for execution by different nodes, to selectively perform different functions defined by the enterprise application.
