Enabling Cloud and On-premises Communication

Context

There are two methods for enabling network communication on and off the cloud, which are suitable for different scenarios. Select either of them based on site requirements.

Through a VPC endpoint

If your local data center has been connected to your VPC through a VPN connection or a direct connection, you can use a VPC endpoint to access CBR through the intranet, so as to migrate VMware backups to the cloud. To access the gateway of CBR, configure the private IP address of the VPC endpoint and private domain name of CBR in the hosts file of eBackup. Then, the VPC endpoint will automatically resolve the domain name to the corresponding IP address, implementing on-premises and cloud communication. For details about VPC endpoints, see What Is VPC Endpoint?

Through the network plane configured with an external IP address

If you have configured an IP address that can connect to external networks when planning the network in your local data center, bind the NIC of the backup storage plane to the IP address when configuring the backup server. Then you can migrate VMware backups to the cloud.

Procedure for Configuring Communication Through a VPC Endpoint

1. Log in to the Huawei Cloudconsole.
   1. Log in to the management console.
   2. Click in the upper left corner and select a region.
   3. Choose Network > VPC Endpoint > VPC Endpoints.

2. Click Create VPC Endpoint in the upper right corner.
3. Buy and configure a gateway VPC endpoint by referring to Buying a VPC Endpoint
4. Buy and configure an interface VPC endpoint by referring to Accessing OBS.

Procedure for Configuring the Communication on the Network Plane Bound with an External IP Address

1. Complete operations in Planning the Network and Installing eBackup.
2. Complete Step 1 to Step 5 in Configuring the Backup Server.
3. In Step 6, bind the NIC of the backup storage plane to the IP address that is connected to external networks.
