(Optional) Creating a VPC

Scenarios

A VPC provides an isolated virtual network for ECSs. You can configure and manage the network as required.

You can create a VPC by following the procedure provided in this section. Then, create subnets, security groups, and assign EIPs by following the procedure provided in subsequent sections based on your actual network requirements.

Procedure

Log in to the management console.
On the console homepage, under Network, click Virtual Private Cloud.
On the Virtual Private Cloud page, click Create VPC.

On the Create VPC page, set parameters as prompted.

A default subnet will be created together with a VPC and you can also click Add Subnet to create more subnets for the VPC.
