                 billing expense. Users won’t actually assemble and configure
                 servers; they’ll choose from a menu of possible virtual ma-
                 chines the one that appears best suited to their task.
                     It will be a key IT skill in the future to know how to map a
                 small set of virtual machine models, make them available to
                 end users as balanced configurations, and stick to the models

                 for maintenance and update purposes instead of letting vari-
                 ations proliferate.
                     Such a procedure disrupts many of the IT organization’s
                 strongest beliefs about proper operation of the data center. End
                 users historically have wanted more than the IT staff can pro-
                 vide, so there is a latent adversary relationship that is ready to
                 pop up if the end users intrude too deeply into data center op-

                 erations. End users getting their hands on the capability to gen-
                 erate virtual servers is little better than welcoming them into
                 the data center to randomly plug in and unplug cables, net-
                 work interface cards, and host bus adapters. To experienced
                 IT professionals, the notion of end user self-provisioning is
                 akin to the inmates taking over the asylum. That may have
                 been the case in earlier eras of computing; in a future gov-
                 erned by cloud operations, however, self-provisioning is going
                 to be a requirement. There will not be enough time or IT staff

                 for people to drop the things they’re doing because another
                 user needs a server configured and installed.
                     Self-provisioning for end users can be set up through vir-
                 tual machine management tools. Whether it succeeds or fails
                 may depend on the skill with which the IT organization can
                 design servers for different tasks. In drafting templates for vir-
                 tual servers, the computer professionals will be lobbied and
