Method and apparatus for extending local area networks between clouds and permanently migrating virtual machines using static network addresses

Abstract

The current document discloses methods and systems for extending an internal network within a first cloud-computing facility to a second cloud-computing facility and deploying a virtual machine or virtual application previously running on a first cloud-computing facility within the context of the extended internal network in the second cloud-computing facility by internal-network extension and redeployment of virtual machines and virtual applications by a stretch-deploy operation, allowing the virtual machine or virtual application to resume execution on the second cloud-computing facility, using the computational and storage facilities of the second cloud-computing facility but depending on network support from the first cloud-computing facility. In addition, the current document discloses a snap operation that permanently relocates a stretch-deployed virtual machine or virtual application to the second cloud-computing facility.
