PrivateLink

Connect your VPCs to services in other VPCs through secure, reliable, and private connections. PrivateLink simplifies network architecture and reduces security risks because network traffic does not traverse the Internet.

Benefits

  • Traffic Security

    Network traffic is distributed within Alibaba Cloud to avoid data leakage. Services are deployed in VPCs and accessed through private connections. This prevents security risks such as attacks from the Internet.

  • Secure and Manageable

    Service providers can create and manage connections and control the bandwidth of connections, but they cannot access the networks of service consumers to reduce any risks. Service consumers can use security controls, such as network ACLs and security groups, to manage connections. Service providers cannot access the networks of service consumers.

  • High Quality and High Reliability

    Network traffic is distributed within zones, and multiple zones are supported to provide high availability. This reduces network latency and improves the quality of communication.

  • Simplified Network Management

    The connected networks are independent of each other. This avoids IP address overlapping and simplifies configurations of routes and security policies. You can access services under other Alibaba Cloud accounts to simplify account management.
