Abstract :
In response to the challenges for application development, deployment, running and maintenance in an open, dynamic Internet platform, the concept of Internetware came into being. It is a new software architecture, which is flexible to evolution, continuously reactive and adaptive to multiple targets. Internetware is able to perceive dynamic changes from internal or external environment, and then do some static adjustment and dynamic evolution according to functional and nonfunctional index to keep a high customer satisfaction. Concept of SOA (Service-Oriented Architecture) is a business-IT-aligned approach in which applications rely on available services to facilitate business processes. Service requestor can flexibility invoke reusable services provided by service provider. However, if your business change, your application consisting of any services need to add, replace, delete any services. Therefore, you have to modify the configuration file or code. Why we don´t apply the mature evolution and self-adaption in Internetware to SOA. Then, changes perceived can drive the changes of application based on SOA and our work is to guide these changes in high-level or business-level rather than work in coding-level. Therefore, this paper presents a CCO model binded the SCA(Service Component Architecture) to provide interfaces, which can be invoked by the evolution system or human being´s guidance. Then, the application based on SOA can self-adapt the changes. In order to achieve our ideas, we develop an modeling tool based on C/S, named CCOtool, to present the mechanism.
