A SOA Repository with Advanced Analysis Capabilities - Improving the Maintenance and Flexibility of Service-Oriented Applications

Abstract

In a service-oriented architecture (SOA), a change or shutdown of a particular service might have a significant impact on its consumers (e.g., IT systems). To effectively cope with such situations, the IT systems affected by a service change should be identified before actually applying the latter. For this purpose, a SOA repository with advanced analysis capabilities is needed. However, due to the numerous complex inter-dependencies between service providers and consumers, it is a challenging task to figure out which IT systems might be directly or indirectly affected by a service change and for which period of time this applies. The paper tackles this challenge and presents the design of an advanced SOA repository enriched with analysis capabilities. In particular, this repository enables automatic analyses to detect already existing problems (as-is analyses) as well as problems that might occur due to future service changes (whatif analyses). Respective analyses will foster the development of robust service-oriented applications.

Service Repository for Cloud Service Consumer Life Cycle Management

“…Authors develop an entity relationship diagram of the service registry that contains service information and metadata, including functional and non-functional properties, service configuration parameters, service provider information, functional description of the service, and QoS attributes. In a recent publication Bauer, et al [13] present the design of an advanced SOA repository enriched with analysis capabilities. The repository contains various types of services and their relationships.…”
