System and method for migrating application virtual machines in a network environment

摘要

A method includes managing a virtual machine (VM) in a cloud extension, where the VM is part of a distributed virtual switch (DVS) of an enterprise network, abstracting an interface that is transparent to a cloud infrastructure of the cloud extension, and intercepting network traffic from the VM, where the VM can communicate securely with the enterprise network. The cloud extension comprises a nested VM container (NVC) that includes an emulator configured to enable abstracting the interface, and dual transmission control protocol/Internet Protocol stacks for supporting a first routing domain for communication with the cloud extension, and a second routing domain for communication with the enterprise network. The NVC may be agnostic with respect to operating systems running on the VM. The method further includes migrating the VM from the enterprise network to the cloud extension through suitable methods.

1. A method, comprising:
managing a virtual machine (VM) in a cloud extension, wherein the VM communicates with a part of a distributed virtual switch (DVS) of an enterprise network, wherein the DVS extends into the cloud extension through a virtual interface of the DVS in the cloud extension; abstracting an interface that is transparent to a cloud infrastructure of the cloud extension with a nested VM container (NVC) in the cloud extension such that the VM executes in the NVC irrespective of hardware and operating system of the cloud infrastructure, wherein the NVC hosts the VM in the cloud extension and facilitates compute, storage and networking services for the VM over a network overlay using emulation techniques; authenticating the NVC with the virtual interface of the DVS in the cloud extension to establish a secure tunnel between the VM and the virtual interface of the DVS through the NVC; intercepting, by the NVC, network traffic to and from the VM; and filtering out, by the NVC, network traffic to the VM from outside the enterprise network.
