Enhancing Soa With Service Lifecycle Management - Towards A Functional Reference Model
نویسندگان
چکیده
Service-orientation aims at decomposing monolithic application systems into services, i.e. functional units that adhere to certain criteria such as standardized interfaces and the ability to be flexibly combined with each other. With the growing diffusion of this paradigm, the management of an increasing number of services along their lifecycle (Service Lifecycle Management SLM) is becoming a success factor. Although comprehensive IT support is not the only ingredient for successfully managing services, it is a contribution to compensate for the growing complexity inherent in any SOA. Surprisingly, the topic of application support in SLM has not yet received systematic coverage in the literature from a functional perspective. This paper proposes a functional reference model for SLM and describes the underlying design process. The model supports practitioners in analyzing, designing and implementing software support for SLM. It further enables to compare and evaluate software solutions and as such it supports IT investment decisions. Scientifically the model represents an approach towards designing information systems in the area of SLM. The paper argues that companies should pursue a best-of-breed approach, as there is no single solution available that comprehensively supports the entire lifecycle. Further, the lack of application support of SLM in practice mainly stems from the absence of integrated solutions and missing knowledge on how to evaluate potential applications.

متن کاملPESOI : Process Embedded Service - Oriented Architecture ∗
Service-Oriented Architecture (SOA) has drawn significant attention recently, and numerous architecture approaches have been proposed to represent SOA-based applications. The architecture of SOA-based applications is different from traditional software architecture, which is mainly static. The architecture of an SOA-based application is dynamic, i.e., the application can be composed at runtime ...
