Message Bus Architectures - Simplicity in the Right Places

Abstract

There will always be a new latest and greatest architecture for satellite ground systems. This paper discusses the use of a proven message-oriented middleware (MOM) architecture using publish/subscribe functions and the strengths it brings to these mission critical systems. An even newer approach gaining popularity is Service Oriented Architectures (SOAs). SOAs are generally considered more powerful than the MOM approach and address many mission-critical system challenges. A MOM vs SOA discussion can highlight capabilities supported or enabled by the underlying architecture and can identify benefits of MOMs and SOAs when applied to differing sets of mission requirements or evaluation criteria.
