Facilitating communications between virtual private clouds hosted by different cloud providers

Abstract:

The disclosed embodiments relate to a system that facilitates communication between virtual private clouds (VPCs) hosted by different cloud service providers. During operation, the system receives a packet from a source at a first router in a first VPC, wherein the first VPC is hosted by a first cloud service provider, and wherein the packet is directed to a destination in a second VPC, which is hosted by a second cloud service provider. If no direct tunnel exists between the first VPC and the second VPC, the system forwards the packet through an intermediate hub to the second VPC, and automatically builds a direct tunnel from the first router in the first VPC to a second router in the second VPC to facilitate subsequent communications between the first and second VPCs.
