This section describes the virtual private cloud (VPC), Direct Connect, and Virtual Private Network (VPN) to help you better understand these network services.

VPC

VPC enables you to create secure, isolated virtual networks. VPC provides you with virtual networks that have no difference with traditional networks. You can easily configure and manage networks on the management console. You can configure security groups, virtual private networks (VPNs), and IP address segments, and allocate bandwidth in a VPC. With a VPC, you can manage and configure internal networks and change network configurations, simplifying network management. You can also customize the cloud server access rules within a security group to strengthen cloud server security protection. The advantages of a VPC are as follows:

Have full control over your virtual networks, for example, creating your own network and configuring the DHCP service.
Create security groups to improve your network security.
Assign elastic IP addresses (EIPs) for use in a VPC, and bind them to cloud servers in your VPC to connect the cloud servers to the Internet.
Connect a VPC to your data center using a VPN for smooth application migration to the cloud.
Communicate with other VPCs using VPC peering connections.

For details, see Virtual Private Cloud Product Introduction.

Direct Connect

Direct Connect helps you establish a dedicated network that connects your local data center to the public cloud. Direct Connect sets up dedicated connections between the Direct Connect gateway and a VPC on the public cloud. With Direct Connect, you can establish network circuits between the cloud and your data center, office, or collocation environment. Direct Connect can effectively reduce network latency and improve network experience.

For details, see Direct Connect Product Introduction.

VPN

VPN establishes a secure, encrypted communication tunnel between the VPN gateway of the VPC on HUAWEI CLOUD and the VPN gateway of your local data center, allowing you to directly use resources in the VPC through the VPN.

By default, cloud servers in a VPC cannot communicate with your physical data center or private network. To enable communication between them, use a VPN.
