<p>The terms orchestration and choreography describe two aspects of emerging standards for creating business processes from multiple Web services. The two terms overlap somewhat, but orchestration refers to an executable business process that can interact with both internal and external Web services. Orchestration always represents control from one party's perspective. This distinguishes it from choreography, which is more collaborative and allows each involved party to describe its part in the interaction.</p><p>Proposed orchestration and choreography standards must meet several technical requirements that address the language for describing the process workflow and the supporting infrastructure.</p>
