Cloud WAN overlay network

摘要

A network device obtains credentials of a customer associated with multiple different cloud providers of which the customer is a subscriber, and establishes, using the credentials of the customer, a cloud wide area network (WAN) overlay network across multiple different cloud computing networks associated with the multiple different cloud providers. The network device, when establishing the cloud WAN overlay network, spins up multiple virtual routers in the cloud resources of the customer at each of the multiple different cloud computing networks, with a different one of the multiple virtual routers being spun up in each of the multiple different cloud computing networks, where each of the multiple different cloud computing networks is associated with a different one of the multiple different cloud providers, and where the multiple virtual routers route data traffic between the different cloud computing networks via the cloud WAN overlay network.
