Service oriented modeling and simulation (M&S) is being pursued by many nations and organizations. Approaches being taken span from the provision of M&S tools and applications via -as-a-Service cloud computing technologies to the actual construction of M&S via service oriented techniques. Often these approaches propose that new technologies are required to achieve service orientation. However, the benefits of service orientation derive from its core concepts of services, high interoperability, and loose coupling. Achieving service orientation in a High Level Architecture (HLA) context requires rethinking how federations are designed including the decomposition of simulation functionality into federates. This paper presents a federation designed in a traditional manner, illustrates how service oriented design alters the federation design, discusses the benefits and drawbacks of the two approaches, and provides possible improvements to the Distributed Simulation Engineering and Execution Process (DSEEP) that may become part of the next iteration of the standard.
