Tencent Cloud provides two network environments, Virtual Private Cloud (VPC) and classic network.
For Tencent Cloud accounts created after June 13, 2017, only VPC is available. We recommend you use a VPC for the following reasons:
Complete features: VPC covers all classic network features, while providing more flexible network services such as custom IP range, routing, Direct Connect, VPN, NAT, etc.
Smooth migration: There is no completely smooth migration solution in the industry (the need to shut down, change private IP, etc). If you need to use a VPC for business development later, the migration process may affect your business.
VPC and Classic Network
VPC
With Tencent Cloud’s Virtual Private Cloud (VPC), you can customize a logical isolated virtual network on the cloud. Even in the same region, different VPCs cannot communicate with each other by default. Similar to the traditional network that you run in your data center, your Tencent Cloud resources, including CVM, Cloud Load Balancer, and TencentDB for MySQL, are hosted on Tencent Cloud’s VPC to give you full control over the environment. For more information on configuration and application scenarios, see VPC. The VPC helps you build more complex network architecture and is suitable for those who are familiar with network management.
Classic network
Classic network is the public network resource pool for all Tencent Cloud users. All your Tencent Cloud resources will be centrally managed by Tencent Cloud.
