VPC

A Virtual Private Cloud (VPC) is a private and isolated virtual network created on Huawei Cloud. The VPC gives you complete control over your virtual network, allowing you to select your own IP address range, create subnets, configure security groups, and even assign EIPs and allocate bandwidth in your network, enabling secure and easy access to your business system.

Application scenarios:

• General-purpose web applications
• Security-demanding services
• Extending your corporate network into the cloud
