Heterogeneous cloud network intercommunication system and method

Abstract

The invention discloses a heterogeneous cloud network intercommunication system. The system comprises at least two cloud platforms belonging to different manufacturers, each cloud platform is providedwith a centralized gateway for each user, an agent module is deployed in each virtual machine of each user of each cloud platform, the agent module of each virtual machine of each user forms a cross-cloud overlay network corresponding to the corresponding user, the centralized gateway is used for two-layer and three-layer flow forwarding of the cross-cloud overlay network corresponding to the corresponding user, and the agent module comprises a first virtual network card, a first overlay network tunnel terminal TEP, a DVS unit, a second virtual network card and a DFW unit connected with the DVS unit, wherein the first virtual network card, the first overlay network tunnel terminal TEP, the DVS unit and the second virtual network card are sequentially connected. By applying the technical scheme provided by the embodiment of the invention, the network layer architectures of the heterogeneous clouds are the same through the agent module and the centralized gateway, real network intercommunication is realized, the deployment mode is simple, and the operation and maintenance difficulty is reduced. The invention further discloses a heterogeneous cloud network intercommunication method which has corresponding technical effects.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a heterogeneous cloud network intercommunication system and method. Background technique [0002] With the rapid development of cloud computing technology, the application of various cloud platforms is becoming more and more extensive. The cloud platforms of different vendors involve the implementation and management of different underlying networks. Connecting heterogeneous cloud networks has always been a problem. [0003] At present, Layer 3 intercommunication among heterogeneous clouds is mainly realized through a VPN (Virtual Private Network, virtual private network). [0004] However, this method only realizes the basic intercommunication of heterogeneous clouds. Different cloud platforms are still not equal and cannot be unified. When virtual machines are migrated, network configurations and security policies must be changed to run normally on the migrated p...
