Managing IT Resources Using Web Services: A Tutorial on the WSDM Standards From The Ground Up

Summary form only given. Industry has been wrestling with the complexity of managing business systems for years. The challenge stems from the variety of application and IT resource providers that enterprises use to build their business systems. A range of management systems co-exist to manage the breadth of resources. The management industry and customers have an opportunity to take advantage of the industry trend towards using Web services for business integration and moving to service oriented architectures for business. It is now possible to garner these same advantages seen in business for management. Building manageable resources and management systems on a Web services foundation is going to cause a profound shift in how enterprises and vendors manage their IT resources in the future. Embracing this shift is going to create more flexible IT infrastructures, better integration of business and IT objectives, and greater end to end management of both IT infrastructures and business processes. This presentation provides a bottoms-up tutorial of Web services distributed management (WSDM), the new OASIS Standard that provides the first step in solving this classic management integration problem. The session will begin with an overview of the SOA based management architecture and WSDM´s place in that architecture relative to other industry standards and initiatives. The technical tutorial will begin with an introduction on WSDL and WS-addressing, specifications on which WSDM depends. The presenters will build on this with an overview of the Web services for resource framework (WSRF) and Web services notification (WSN) OASIS specifications and discuss how they are used by WSDM. Finally, the session will explore WSDM components, management using WS (MUWS) and WSDM management of Web services (MOWS). MUWS defines how to represent and access the manageability interfaces of any IT resource as Web services. MOWS defines how to manage Web services as resources and how to de- - scribe and access that manageability using MUWS. Concrete customer issues solved by WSDM will also be highlighted as well as how CIM modeled resources can be accessed using WSDM. Apache MUSE and IBM Developerworks Toolkits will be used to illustrate the programming techniques
