With the development of cloud computing and virtualization technologies, enterprises accelerate their digital transformation and increasingly rely on the public cloud for mission-critical IT service systems and applications. Against this backdrop, enterprises are now focusing on how to quickly migrate to the cloud and enable flexible communication between branch sites and multiple clouds. Huawei SD-WAN provides the following multi-cloud interconnection capabilities to meet different service requirements. Huawei vCPEs are deployed on multiple clouds, such as Huawei Cloud, Alibaba Cloud, AWS, and Microsoft Azure, to implement service interworking between cloud sites. Automatic deployment of cloud sites enables vCPEs to be automatically started on the cloud, ensuring fast service migration to the cloud. Cloud sites and VPCs are interconnected to implement flexible access between branch sites and clouds.
