Virtual private cloud (VPC) builds an isolated and private virtual network environment for cloud resources such as ECS, CCE and RDS. You can fully control your own private network. The rich functions provided by a VPC help you flexibly manage the cloud network, including creating a subnet, setting a security group and a network ACL, managing a routing table and applying for an Elastic IP and bandwidth. In addition, you can connect a VPC to traditional data centers through services such as CDA and VPN, flexibly integrate resources and build a hybrid cloud network.
