Greetings, Is there general agreement on what a "Service" is and what an "Application" is in the context of a SOA?
Some of the definitions I've come across for a Service are: "A service is a location on the network that has a machine-readable description of the messages it receives and optionally returns" -- SOA with Web Services by Eric Newcomer & Greg Lomow "A discrete unit of logic that exist autonomously that conform to a set of principles that allow them to evolve independently, while still maintaining a sufficient amount of commonality and standardization" -- SOA by Thomas Erl Others include - "A service is defined as a computer program that provides a self-contained, stateless function, which accepts one or more requests and returns one or more responses through a well-defined interface." Definition of Application range from "An application is a computer program with a user interface" to others much more esoteric. While I don't exactly expect everyone to agree, is there at least a description of what a Service is and an Application is in a SOA that folks can actually live with?
