End to End Management

Are you ready? End-to-End management, across multiple components, in a distributed heterogeneous environment is fast becoming realty and quickly becoming a requirement of management and customers alike. It is no longer sufficient to manage personal computers, subnets, the network core and individual systems in isolation. These components all interoperable to provide connectivity and services. Information passes between these boundaries. Management must pass across these boundaries as well.

The Distributed Management Task Force (DMTF) is leading the development, adoption and unification of management standards and initiatives for desktop, enterprise and internet environments. Working with key technology vendors and affiliated standards groups, the DMTF is enabling a more integrated, cost-effective, and less crisis-driven approach to management through interoperable management solutions.

One such standard, is the Common Information Model (CIM). CIM  is a model for describing overall management information in a network / enterprise environment. CIM is comprised of a Specification and a Schema. The Specification defines the details for integration with other management models, while the Schema provides the actual model descriptions.

The CIM Specification is the language and methodology for describing management data. The CIM Schema includes models for Systems, Applications, Networks (LAN) and Devices. The CIM Schema will enable applications from different developers on different platforms to describe management data in a standard format so that it can be shared among a variety of management applications. The xmlCIM Encoding Specification defines XML elements, written in Document Type Definition (DTD), which can be used to represent CIM classes and instances. The CIM Operations over HTTP specification defines a mapping of CIM operations onto HTTP that allows implementations of CIM to interoperate in an open, standardized manner and completes the technologies that support the Web Based Enterprise Management (WBEM) initiative.

Finally, companies implementing the WBEM initiative should be able to realize and recognize these value adds:

  1. Reduced Total Cost of Ownership by actually managing systems and devices with less man-hours as a result of interoperability
  2. Improved Time to Market (and possibly gain a competitive advantage) using standards based models
  3. Reduced Development Cost using and re-using existing standards models, no need to "re-invent the wheel" every time
