Virtual Private Cloud
Virtual Private Cloud (VPC) allows you to provision logically isolated virtual private networks for cloud resources, such as cloud servers, containers, and databases. You can create subnets, security groups, network ACLs, route tables, and more to manage cloud resources flexibly. You can also use EIPs to connect cloud resources in VPCs to the Internet, and use Direct Connect and VPN to connect on-premises data centers to VPCs to build a hybrid cloud network.
