ADJUSTING RESOURCE USAGE FOR CLOUD-BASED NETWORKS

A cloud marketplace system can be configured to communicate with multiple cloud computing environments in order to ascertain the details for the resources and services provided by the cloud computing environments for optimizing resources utilized by virtual machines. The cloud marketplace system can be configured to determine the resource and service data for the cloud computing environments and select a set of resource servers for instantiating the virtual machines based specifications of the virtual machines and parameters of the instantiation. The cloud marketplace system can be configured to periodically monitor the cloud's resources and migrate the virtual machines if resources become available that more closely match the parameters of the virtual machines.
