This stipulated agreement not only identifies service??™s offerings, but also can
be leveraged for service consumption planning, reuse analysis, and security arrangements.
6. Intermediaries and Mediation. The service-oriented modeling discipline advocates
mediation methods to enable loose coupling implementations, overcome service interoperability
challenges, and increase reuse of software assets. Thus, intermediaries should play
a major role in service design and isolation of distributed service-oriented organizational
assets.
MAJOR INFLUENCES ON SERVICE RELATIONSHIPS
Services must often work in partnership, be part of certain computing environments, and participate
in business or technological initiatives designed to provide organizational solutions to
problems that arise. Indeed, the environment in which services operate typically dictates dependency
conditions that affect their relationships and bind their operations. But the organizational
landscape and a myriad of launched projects are not the only factors that closely tie services.
So what are the driving aspects of service design relationship? In a distributed serviceoriented
environment, services communicate by exchanging messages. Atomic and composite
services and service clusters must collaborate to enable efficient message distribution across
networks. Thus, message paths, orchestration, and delivery requirements influence a service??™s
design relationship and its ability to flawlessly execute transactions in a distributed computing
landscape.
