Web Services and the Data Center of Tomorrow. In this two-part column, Preston Gralla looks at IBM's and Sun's visions for utility/grid computing. IBM uses web-services standards and protocols at the heart of its Globus Toolkit 3.0 (GT3). (See the Globus Alliance website.) But even IBM's Kerrie Holley believes "we may be five to ten years away from taking full advantage of powerful grids." In the meantime, "IBM will be using [web services] for workload management and control" perhaps as early as next year.
"In the words of Sun Software Chief Technology Officer, John Fowler, 'In the future, the management of the data center will move from managing boxes to managing services.'" He sees a three-stage process of enterprises moving toward the data center of the future:
- Web services to express service interfaces to applications.
- Identity systems, directories, and portals to describe the entire data center and all of its infrastructure.
- Management technologies that let you change your data center on an as-needed basis.
Fowler says that "changes are already underway. A variety of enterprises are already at stages 1 and 2 of the process." [Source: The Web Services Advisor]
