Connect VPCs

CEN allows cloud resources that are deployed in different regions around the world to communicate with each other. CEN ensures that the IP addresses are unique and do not conflict with each other. In addition, CEN automatically forwards and learns multi-node routes through controllers to rapidly converge global routes.

CEN provides low-latency and high-speed network transmission. CEN ensures that on-premises networks communicate with each other at the highest data transfer rate supported by the device ports. CEN provides network connections with lower latency than Internet connections.

CEN has deployed access points and nodes in more than 60 regions in the world to support nearest access to Alibaba Cloud. Compared with communication over the Internet, CEN connections provides lower network latency.

CEN provides at least four standby connections between two nodes. Therefore, CEN ensures high availability for your services. If some connections fail to work, the standby connections take over. This way, CEN ensures that your service is not interrupted and prevents network jitter.

CEN can monitor networks in a systematic manner and automatically detects route conflicts that are caused by system changes. This ensures the stability of your services.

VPN Gateway uses the IKE and IPsec protocols in data transmission to ensure data security.

The active-active architecture enables VPN Gateway to perform failovers within seconds. This ensures that your service and session are not interrupted when errors occur.

VPN Gateway establishes encrypted connections over the Internet, which are more cost-efficient than leased lines.

VPN Gateway supports an out-of-the-box feature and configurations immediately take effect.
