ABSTRACT: The current design for the service registry architecture lacks a well-organized categorical structure and service- aware exploration method to enable effective real-time and offline services selection. To address this issue, this paper proposes an architectural framework and enabling technology for a business services analyzer that supports analyzing, clustering and adapting heterogeneous services for dynamic application integration. The proposed systematic services exploration methodology includes services categorization, services clustering and services exposure. By applying pattern recognition algorithm, we build a manageable feature space that is able to select and expose a service to serve the request from a repository with "large" amount of available services. To illustrate our design, we also provide a research prototype called Services Litmus Test (SLT) toolkit, which provides a flexible software platform for executing systematic services exploration procedures. The GUI based human assisted tune-up interface makes it very convenient for the services system designers to customize their design according to the adaptive system requirements.

ABSTRACT: Many systems are built with very little foresight for incorporating changes resulting from new requirements. This paper provides a systematic way and normative guidance to analyze the variations in SOA solution design. During SOA solution design, two types of change- oriented analysis patterns, variation-oriented analysis (VOA) and event-driven change analysis (EDCA), are proposed to create a resilient design that is adaptive to changes. Specifically, a meta-data model and associated assets for solution design are introduced first to capture the information context for SOA solution design. Then a new change propagation analysis process is presented to summarize the variation identification, variation impact assessment, variation impact path identification, variation analysis and decision making. Based on these two techniques, this paper creates a set of normative guidance for the variation oriented design. These guidelines include but not limited to the artifact type, variation description, variation type, variation artifacts, and impact analysis.
