Abstract: A method for dynamic reservation of cloud and on premises resources for software execution is disclosed. The method may be comprised of: receiving the specification for the resources needed for the software, evaluating the availability of resources and reserving the resources for the software. The method may include a protocol to discover, evaluate availability, negotiate terms and create a reservation contract for software execution resources based on the required specification. This can be implemented using resource agent modules that represent available software execution resources (e.g.: CPU, memory, storage, network . . . ) and reservation agent modules that are used for communicating with the resource agent modules for reserving software execution resources. In addition, monitoring agent modules are used to monitor the actual software execution reservation contract.
