Web Services-based Host Resources And Services Resource Management Research

With the development of network technology, enterprise systems management environment has changed greatly. The managed objects include servers, middleware, and application software running on computer besides simple network devices. System management environment is heterogeneous because that the managed resources and management protocals are different.In this case, system management must address the the problems in management of complex objects, management protocals diversity, management function distrubition, management of large scale and diverse management needs.The existing management standards and traditional systems management model can not solve these problems.Because of its platform-independent, language-independent advantages, Web service inrecent years is widely used to solve application integration issues in heterogeneous platforms. By exposing the managed resources and management functions through Web Service, It can provide universal method of accessing and exchanging management information, and promote the interaction between the management software and managed resources in heterogeneous IT environment. And it also meets the needs of SOA (Service Oriented Architecture) service-oriented architecture.(Web Service Management) and WSDM-MUWS (Web Services Distributed Management-Management Using Web Services) are two main kinds of specifications of using Web services technology in system management field. This paper introduces the concept of system management, analyzes and compares the content and features of the two Web service system management specifications. Based on that, this paper proposes a WS-Management based system management framework. Comparing with the traditional system management model, this framework is loose-coupled and has good scalability.To shield the heterogeneity of the underlying host resources, this paper introduces CIM (Common Information Model) for modeling managed resources, designs and implements a host resource management example basing on an open-source project Wiseman, demonstrates that Web service based host resource management is feasible. As for service resources management, the paper analyzes the content and features of Web service management, presents a WS-Management based service management framework, which is able to manage both simple Web services and composite Web services. In this service management framework, managed web services must expose the management interface as Web Service. It is not widely adopted by Web Service providers. At last, this paper proposes finite state machine framework based Web services monitoring framework. By monitoring and analysing the interaction messages between Web service consumers and providers, it provides monitoring and error diagnosis function. This monitoring framework can work as a replacement for standards-based Web services management approach when managed web services don't provide management interface.
