Application Scenarios

VPC Endpoint establishes a secure and private channel between a VPC endpoint (cloud resources in a VPC) and a VPC endpoint service in the same region.

You can use VPC Endpoint in different 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 the purposes of:

Accessing OBS or DNS using VPC endpoint 1
Accessing ECS 1 in VPC 1 using VPC endpoint 2
Accessing 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

With VPC Endpoint, resources in two different VPCs can communicate with each other despite of logic isolation between them as long as the two VPCs are in the same region.
