Embodiment Construction

[0016] overview

[0017] An example method includes managing a virtual machine (VM) in a cloud extension, abstracting an interface transparent to a cloud infrastructure of the cloud extension, and intercepting network traffic from the VM, wherein, VMs are able to securely communicate with the corporate network. A VM can be part of a Distributed Virtual Switch (DVS) of an enterprise network. In particular embodiments, the method may further include providing a secure tunnel between the VM and the cloud gateway located in the cloud extension. In other embodiments, managing the VM may include loading the VM, starting the VM, stopping the VM, restarting the VM, monitoring the health of the VM, providing resource utilization data associated with the VM, and providing console access to the VM.

[0018] In other embodiments, the method may also include migrating the VM from the enterprise network to the cloud extension. The migration may include establishing a secure tunnel at t...

Abstract

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.

Description

technical field [0001] The present disclosure relates generally to the field of communications, and more particularly to systems and methods for migrating application virtual machines in a network environment. Background technique [0002] The virtualization trend in the information technology (IT) field is driving the development of many virtualization technologies such as network virtualization. Network virtualization solutions can consolidate multiple physical networks into one virtual network. They can also logically segment a single physical network into multiple logical networks. Partitions can be added to quickly scale the network for business needs. Network virtualization represents a new IT paradigm that challenges existing physical network deployment models. Network virtualization provides many benefits, such as extending the availability of a single IT asset to multiple users, managing multiple IT assets as a single resource, providing dedicated virtual network...
