Virtualized data centers host multiple applications with distinct objectives in a shared infrastructure. Accommodating several dynamic applications in virtual data centers is a challenging task for cloud providers. Current provisioning solutions focus on a limited set of objectives that may not be suited for the increasing number of applications deployed in data centers every day. In this paper, the authors propose an adaptive provisioning architecture for virtualized data centers based on allocation paradigms. A paradigm translates high-level application goals to objectives, allocator instances, and actions that actually provision customized virtual infrastructures to applications.
