1. A computer-implemented method for selecting pre-provisioned virtual machines (VMs) to process workload requests in a networked computing environment, comprising: receiving a workload request in a computer storage medium; identifying a set of software programs needed to process the workload request; selecting a set of VMs from a pool of pre-provisioned VMs having the set of software programs in the networked computing environment, the set of VMs being selected based on at least one of the following: a length of time to install the set of VMs; a probability of the set of VMs being in demand, or a quantity of the set of VMs having the set of software programs, the selecting of the set of software programs further comprising: looping through all of the pre-provisioned VMs having some combination of the set of software programs; calculating times associated with traversal paths for each combination; and selecting the set of VMs based on the shortest time associated with a traversal path indicating a shortest length of time to install the set of VMs; installing the set of VMs; and processing the workload request using the set of software programs in the set of VMs.
