Using a Cloud Connection to Connect VPCs in the Same Region

Procedure

Preparations

Before creating a cloud connection, you need to sign up for a HUAWEI ID, enable Huawei Cloud services, complete real-name authentication, and top up your account. Ensure that your account has sufficient balance.

1. Sign up for a HUAWEI ID, enable Huawei Cloud services, and complete real-name authentication.
   If you already have a HUAWEI ID, skip this part. If you do not have a HUAWEI ID, perform the following operations to create one:

   1. Sign up for a HUAWEI ID and enable Huawei Cloud services.
   2. Complete real-name authentication.
2. Top up your account.

   Ensure that your account has sufficient balance. For details about how to top up an account, see Topping up an Account.

Step 1: Create a Cloud Connection

1. Go to the Cloud Connections page.
2. In the upper right corner of the page, click Create Cloud Connection.
3. Configure the parameters based on Table 1.

   Table 1 Parameters for creating a cloud connection

   Parameter	Description
   Name	Specifies the cloud connection name. The name can contain 1 to 64 characters. Only letters, digits, underscores (_), hyphens (-), and periods (.) are allowed.
   Enterprise Project	Provides a cloud resource management mode, in which cloud resources and members are centrally managed by project.
   Scenario	VPC: VPCs or virtual gateways can use this cloud connection.
   Tag	Identifies the cloud connection. A tag consists of a key and a value. You can add 20 tags to a cloud connection. NOTE: If a predefined tag has been created on Tag Management Service (TMS), you can directly select the corresponding tag key and value. For details about predefined tags, see Predefined Tags.
   Description	Provides supplementary information about the cloud connection. The description can contain no more than 255 characters.

4. Click OK.

Step 2: Load Network Instances

Load the VPCs that need to communicate with each other to the created cloud connection.

1. Go to the Cloud Connections page.
2. Click the name of the cloud connection to go to the Basic Information page.
3. Click the Network Instances tab.
4. Click Load Network Instance.
5. Configure the parameters based on Table 2 and click OK.

   Table 2 Parameters for loading a network instance to a cloud connection

   Parameter	Description
   Account	Specifies the account that provides the network instance. Select Current account.
   Region	Specifies the region where the VPC you want to connect is located.
   Instance Type	Specifies the type of the network instance that needs to be loaded to the cloud connection. There are two options: VPC Virtual gateway Select VPC.
   VPC	Specifies the VPC you want to load to the cloud connection. This parameter is mandatory if you have set Instance Type to VPC.
   VPC CIDR Block	Specifies the subnets in the VPC and custom CIDR blocks. If you have set Instance Type to VPC, you need to configure the following two parameters: Subnet: Select one or more subnets in the VPC. Other CIDR Block: Add one or more custom CIDR blocks as needed.
   Remarks	Provides supplementary information about the network instance.

6. Click Continue Loading if you need to load another network instance. If you do not need to load another network instance now, close the dialog box and view the loaded network instance on the Network Instances tab.
