VPC private intercommunication within a region

VPCs in the same region can request to access the other’s resources through network communication. Express Connect enables private network communication between VPCs, which avoids unstable public networks and reduces the risk of data theft during transmission.

Cross-regional VPC private intercommunication

VPCs can request to access to other VPCs in different regions. Express Connect enables private network communication between VPCs, which avoids unstable public networks and reduces the risk of data theft during transmission.

Cross-account VPC private intercommunication

VPCs can request to access other VPCs under different accounts. Express Connect enables private network communication between VPCs, which avoids unstable public networks and reduces the risk of data theft during transmission.

Access to VPC through physical connection

With physical connection in place, you can create private network connections between your on-premises IDC and VPC, which avoids unstable public networks and reduces the risk of data theft during transmission.

Access to VPC through our partners

Alibaba’s partners can help create private network connections between our on-premises IDC and VPC, which avoids unstable public networks and reduces the risk of data theft during transmission.

Two VPCs share a self-built SNAT gateway

VPC 1 has a self-built SNAT gateway that enables ECSs in VPC 1 to access public networks. With Express Connect connecting VPC 1 and VPC 2, instances in VPC 2 can also access public networks using the self-built SNAT gateway.
