Virtual machine allocation analysis for physical network deployments

Embodiments of the present disclosure comprise considering the performance of an application under different candidate physical network topology configurations for a set of virtual machines (VMs) for an application. Given different physical network topologies corresponding to the logical topology for the application, each physical network topology may be analyzed to quantify the performance of the application based upon one or more metrics. In one or more embodiments, the metrics may include throughput, latency, and network resource usage, and these metrics may be formed into a performance set. The set of values provide a means by which the different physical network topology deployments may be compared. Based upon the comparison, a deployment of the VMs on the physical network topology may be selected and implemented; or alternatively, when input expected application performance parameters are satisfied by the metrics, the corresponding physical topology may be chosen.
