In a computer-implemented method for managing network resources within a server cluster, a request for provisioning of an application to be executed by the server cluster may be received. A required amount of bandwidth for the application, and a resource allocation of network bandwidth for the application, may be determined. The application may be provisioned to a network resource within the server cluster with the resource allocation of network bandwidth. It may be determined that an additional application, which utilizes bandwidth in bursts, is to be provisioned to the server cluster. It may further be determined that the server cluster can support bandwidth requirements of the additional application, at least in part by determining that one or more applications currently provisioned to the server cluster are also utilizing bandwidth in bursts. The additional application may then be provisioned to another network resource within the server cluster.
