What is Virtual Private Cloud?

Virtual Private Cloud (VPC) allows you to provision a logically isolated section on Kingsoft Cloud where you can launch Kingsoft Cloud resources in a virtual network that you define and have complete control over. You can launch resources such as Kingsoft Cloud Elastic Compute (KEC), Elastic Physical Compute (EPC), Server Load Balancing (SLB), and cloud databases. In addition, you can also build a hybrid cloud by connecting a VPC with your existing data center through Direct Connect or IPsec VPN to achieve smooth migration to the cloud.

What does VPC provide?

• Simplified operations and maintenance (O&M): In a VPC, you can customize network ranges, create subnets, and configure route tables and security group rules by using the VPC console or API. The software-defined networking method helps save device and O&M costs.
• Cross-account communication: Through the Peering service, you can interconnect cloud resources deployed in multiple places within one minute, and implement geo-redundancy. In addition, through cross-account peering connections, you can also realize data communication with other partners on Kingsoft Cloud and establish an open cloud ecosystem.
• High-performance Internet access: Network Address Translation (NAT), Elastic IP (EIP), and SLB help you break the bottlenecks of network performance. NAT provides up to 15 Gbit/s bandwidth and multi-node hot standby.
• Deployment of a hybrid cloud: You can use IPsec VPN or Direct Connect to connect a VPC to your data center. You can flexibly scale cloud resourcse such as KEC instances based on your business needs, and can directly connect physical servers to the VPC. The hybrid cloud mode helps you reduce the cost of IT O&M while ensuring the security of your mission-critical data.
• Comprehensive security control: A VPC is a naturally isolated network environment. Access control lists (ACLs) and security groups are used to control network access from subnets and servers, and access control based on protocols and ports is supported, meeting your network security requirements.

What are the differences between a VPC and a basic network?

All users on a basic network share a network resource pool, and they are not logically isolated. Private IP addresses of users are assigned by the system, and the same private IP address cannot be assigned to different users.
A VPC is a logically isolated virtual network created in a Kingsoft Cloud data center. In a VPC, you can customize network ranges as needed, use any IP addresses in the VPC, and configure routing policies and Direct Connect. A VPC has higher flexibility and security than a basic network.
