Active Customization-Oriented Adaptive SOA with Runtime Exception Handling

Abstract

Service has become the basic way to access and enlarge the capability of all kinds of infrastructure. But now, service-based software system based on SOA lacks of runtime iterative re-aggregation process management and exception handling. And current approaches can't align services aggregation with requirements to overcome the runtime exceptions and deal with services resource insufficiency and context changes. This paper concentrates on the adaptability of service-based system, i.e. runtime exception handling mechanism driven by personalized requirements. The following progresses have been achieved. (1) Service requester-centric adaptive SOA with runtime exception handling has been investigated. (2) Mathematical basis and related algorithm for adaptive SOA have been built and verified. Combination of theoretical research and empirical validation, the paper tries to provide a technical operational and cost-effective solution for SOA with adaptive mechanism and promoting the adaptive ability for runtime requirements evolution.
