Virtual machine management among networked servers coupled for data communications with a data communications network that includes a network device and a Virtual Machine Management Module (‘VMMM’), where VM management includes: monitoring, by the network device, network traffic of applications executing in virtual machines of the servers; determining, in dependence upon the monitored network traffic, whether a particular application's network traffic exceeds a predetermined threshold, the particular application executing in a particular virtual machine of a particular server; if the particular application's network traffic exceeds the predetermined threshold, allocating, by the VMMM, an additional virtual machine in a different server; and instantiating, by the VMMM, in the additional virtual machine at least one application.
