The mainframe is not dead, but it has certainly evolved. Says Carl Greiner, senior vice president at Ovum, the mainframe environment has changed from monolithic and centralized, to distributed and tightly intertwined with other computing resources in a complex enterprise infrastructure. As a result, mainframe operations staff faces a significant challenge: how to effectively manage the mainframe in this distributed computing environment.
Traditional mainframe management practices do not scale well to the distributed environment. These practices were developed when the mainframe was viewed as a resource, separate from the distributed IT infrastructure. Consequently, IT was slow to integrate mainframe management with the management of the IT infrastructure's distributed components. IT can no longer view the mainframe as separate from the distributed environment. Instead, IT must evolve its mainframe management practices to keep pace with the evolved distributed environment of the mainframe, managing it as an integral part of the IT infrastructure and from a business perspective. That's the only way IT can align more closely with the business and improve service delivery, while holding the line on, or even decreasing, costs.
