A networking method including receiving, at an edge router of a cloud data center, a virtual private cloud (“VPC”) network communication from a private network via a dedicated physical connection line to the edge router. The VPC network communication is forwarded to a gateway hardware group via a first connection using Virtual Extensible Local Area Network (“VXLAN”) technology. The VPC network communication is then forwarded from the gateway hardware group to VPC of a user of the private network via a second connection using VXLAN technology to access a virtual machine (“VM”).
