Creates a virtual private cloud (VPC).
Usage notes
When you call this operation, take note of the following rules:
- You can specify only one CIDR block for each VPC.
- After you create a VPC, you cannot change its CIDR block. However, you can add secondary IPv4 CIDR blocks to the VPC.
- In each VPC, cloud services can use a maximum of 60,000 private IP addresses. You cannot increase the quota.
- After you create a VPC, a vRouter and a route table are automatically created.
- At most three user CIDR blocks can be added to a VPC. If a user CIDR block includes another user CIDR block, the one with the shorter subnet mask takes effect. For example, if 10.0.0.0/8 and 10.1.0.0/16 are specified, only 10.0.0.0/8 takes effect.
- The CreateVpc operation is asynchronous. After you send a request, the system returns a request ID and runs the task in the background. You can call the DescribeVpcAttribute operation to query the status of a VPC:
- If the VPC is in the Creating state, the VPC is being created.
- If the VPC is in the Created state, the VPC is created.
- You cannot repeatedly call the CreateVpc operation to create default VPCs within the specified period of time. However, you can repeatedly call this operation to create custom VPCs within the specified period of time.
