A VPC has a region attribute (such as Guangzhou), while a subnet has an availability zone attribute (such as Guangzhou Zone 1). A VPC can be divided into one or more subnets. Subnets in the same VPC can interconnect with one another by default, while subnets in different VPCs (regardless of whether they are in the same region) are isolated by default. | Select the configured VPC and subnet from the dropdown list. If the existing network does not meet the requirements, click Create VPC or Create Subnet to create the required network environment. |
