摘要

在过去几年中,对不断变化的业务需求和环境条件进行动态系统适应已经成为IT的一个常见需求。尽管服务计算不断创新,但目前的技术无法跟上业务日益增长的需求,更快地进入市场。服务细化周期(SRC)被提出用于通过将现有服务与集成策略组合在一起来提供创建新服务的灵活性和能力。我们使用现有技术(如Web Services、XACML和WS-BPEL)为SRC开发并部署了一个服务执行环境(SEE)。作为概念验证原型,我们还开发了一个在线无线电服务,该服务广泛使用了SRC的关键功能,并由我们的SEE执行。

Flexible Execution of Adaptable Composed Services
Dynamic system adaptation to continuously changing business requirements and environment conditions has been a common demand for IT over the last years. In spite of constant innovation in service computing, current technology is not able to keep up with business ever growing need faster time to market. The Service Refinement Cycle (SRC) has been proposed for providing flexibility and power for creating new services by composing existing services with integrated policies. We developed and deployed a Service Execution Environment (SEE) for the SRC using existing technology, such as Web Services, XACML and WS-BPEL. As a proof of concept prototype, we also developed an Online Radio Service that makes extensive use of the key SRC features and is executed by our SEE.
