Abstract: A general development and automatic management platform for e-service systems is essential for e- service systems to always deliver satisfying, up-to- date, and trustworthy services cost-effectively to its customers, no matter where they are, when they want them, and how they access them. Following an application-driven approach, this paper derives the functional architecture of a general development and automatic management system, named AMSES. The AMSES aims for providing automatic management for the lifecycles of multiple distributed e-service systems. The AMSES is composed of two kinds of functionalities: one for managing the operational functions and development of an e-service system, and another for managing the interactions among multiple e-service systems. To support the specified functionalities of AMSES, this paper presents four general management mechanisms: VOE (Virtual Operating Environment), VS (Virtual Service), i-resource (Intelligent resource) and a-resource (Active resource). The VS mechanism supports diverse services and resource outsourcing, and to provide protection as well as performance monitoring. i-resource mechanism and a-resource mechanism cooperatively implement resource virtualization of heterogeneous resources and distributed self-management of resources and service the VOE mechanism provides encapsulation and protection for an e-service system. In the AMSES, an e-service runtime system is represented as a group of distributed i-resources, where each i-resource is realized with a group of a-resources. The self- management is realized in four control loops with different response time-scales. At last, the functional architecture of the AMSES is derived based on the four mechanisms. The AMSES is an endeavor that aims to provide a common vision to derive a general and automatic management platform for e-service systems. This paper also tries to lay out a consistent framework for those related research activities for further research in this area.
