Process Description

To enable network communications among VPCs under the same account within a region, create a cloud connection and load the VPCs to it.

Network Communications Among VPCs of the Same Account shows an example.

Figure 1 Network communications among VPCs under the same account within the same region

Figure 2 illustrates how you can enable network communications among VPCs under the same account in the same region.

Figure 2 Process for enabling network communications among VPCs

You can use both Cloud Connect and VPC Peering to enable communications among VPCs.

• If there are two VPCs in the same region, choose VPC Peering and create a VPC peering connection between the VPCs.
• If there are multiple VPCs, use Cloud Connect, regardless of if they are in the same region or different regions.

Procedure

1. Create a cloud connection.
   1. Log in to the management console.
   2. Hover on the upper left corner to display Service List and choose Networking > Cloud Connect.
   3. On the Cloud Connections page, click Create Cloud Connection.
   4. Configure the parameters based on Table 1.

      Table 1 Parameter description

      Parameter	Description	Example Value
      Name	Specifies the cloud connection name. The name can contain 1 to 64 characters, including letters, digits, underscores (_), hyphens (-), and periods (.).	CC_01
      Enterprise Project	Provides a cloud resource management mode, in which cloud resources and members are centrally managed by project.	default
      Description	Provides supplementary information about the cloud connection. The description can contain a maximum of 255 characters.	N/A

   5. Click OK.

      

2. Load network instances.

   Load the VPCs that need to communicate with each other to the cloud connection based on your network plan.

   1. In the cloud connection list, locate the cloud connection and click its name.
   2. Click Network Instances.
   3. Click Load Network Instance.
   4. Select the VPC you want to load.

      Configure other parameters based on Table 2 and then click OK.

      Table 2 Parameter description

      Parameter	Description	Example Value
      Account	Specifies whether network instances are from the current account or another account.	Current account
      Region	Specifies the region where the VPC you want to connect is located.	N/A
      Instance Type	Specifies the type of the network instance. Two options are available, VPC and Virtual gateway. Currently, you can load only VPCs across accounts.	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-w2
      VPC CIDR Block	Specifies the subnets of the VPC you want to load and the custom CIDR blocks. If you have set Instance Type to VPC, configure the following two parameters: Subnet: Select one or all subnets of the VPC. Other CIDR Block: Add one or more custom CIDR blocks as needed.	Subnet: subnet-test Other CIDR Block: 192.168.3.0/16
      Remarks	Provides supplementary information about the network instances.	N/A

   5. In the dialog box indicating that the VPC has been loaded to the cloud connection, if you want to load another VPC, click Load Another Instance. Then click the Network Instances tab to view the VPCs you loaded.
