Overview

Scenarios

If you want to access a cloud service like OBS from an IDC, you can connect the IDC to your VPC using a VPN connection or a direct connection and then connect your VPC to a cloud service using a VPC endpoint.

This section describes how to configure a VPC endpoint to access OBS using its private address from an IDC.

Figure 1 Accessing OBS using its private address from an IDC

Figure 1 shows the process of connecting an IDC to a VPC over VPN or Direct Connect to access DNS and OBS using two VPC endpoints, respectively.

A VPC endpoint comes with a VPC endpoint service. Before you create a VPC endpoint, ensure that the target VPC endpoint service is available.

The following VPC endpoint services are required:

• VPC endpoint service for DNS: resolves the OBS domain name at the IDC.
• VPC endpoint service for OBS: provides the OBS service for the IDC.

Configuration Process
