Application Scenarios

High-Speed Access to Cloud Services

After you connect an IDC to a VPC using VPN or Direct Connect, you can use a VPC endpoint to connect the VPC to a cloud service or one of your private services, so that the IDC can access the cloud service or private service.

Figure 1 Access to cloud services

Figure 1 shows the process of connecting an IDC to VPC 1 over VPN or Direct Connect, for accessing:

• OBS or DNS using VPC endpoint 1
• ECS 1 in VPC 1 using VPC endpoint 2
• ECS 2 in VPC 2 using VPC endpoint 3

For cloud migration, VPC Endpoint has the following advantages:

• Simple and efficient

  The IDC is directly connected to the VPC endpoint service over a private network, reducing access latency and improving efficiency.

• Low cost

  With VPC Endpoint, your IDC can access cloud resources over a private network, reducing your costs on public resources.

For details, see Configuring a VPC Endpoint for Accessing the Private IP Address of OBS over Private Networks.

Cross-VPC Connection

VPC Endpoint enables your resources in two different VPCs within a region to communicate with each other.

VPC endpoints and VPC peering connections are different in security, communications methods, route configurations, and more.

For more information, see What Are the Differences Between VPC Endpoints and VPC Peering Connections?

Figure 2 Cross-VPC connection

Figure 2 shows how an ECS in VPC 1 uses a VPC endpoint to access a load balancer in VPC 2 over a private network.

VPC Endpoint has the following advantages:

• High performance

  Each gateway supports up to one million concurrent connections.

• Simplified operations

  VPC Endpoint resources can be created within seconds and take effect quickly.
