Architectural Considerations in Predictable Component Assembly: A Service-Oriented Perspective

1Abstract Software components are deployed in tightly coupled environments within the context of a component model. Techniques such as PredictionEnabled Component Technology (PECT) [4] combine component technologies with analysis models to address the issue of consumer trust in the quality of assemblies. Service-oriented thinking and challenges surrounding distributed environments are not new, yet they raise certain prominent issues that need to be addressed when crossing organizational and deployment boundaries. This paper describes a common architecture for enterprise application assembly where the focus lies with components and service-assemblies. We consider the aspects surrounding predictability using a service-oriented perspective. Contemporary industry technologies such as .NET and J2EE are used to present a case study of predictable assembly in a broader service-oriented architectural scope. Additional aspects are identified when considering a service-oriented perspective.
