This article introduces the knowledge of "whether vpc is a cloud server". In the operation of actual cases, many people will encounter such a dilemma. Then let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Is vpc a CVM? The full name of vpc is Virtual Private Cloud (Virtual Private Cloud). The VPC service launched by various cloud service providers generally refers to the isolated and private virtual network environment that users apply for in the cloud service provider. Users are free to configure IP address ranges, subnets, security groups and other services within the VPC.

Advantages of CVM VPC network:

1. Safety

Due to the existence of switches and routers in the private network, it can be subnetted like the traditional network environment. Different CVMs within each subnet are interconnected with the same switch, and routers are used between different subnets.

The internal networks of different proprietary networks are completely isolated and can be interconnected through externally mapped IP (elastic public networks IP and NAT IP).

two。 Controllable

Users can flexibly control the inbound and outbound traffic of accessing cloud resources in the private network through security group rules, access control whitelist and other methods.

3. Easy to use

You can quickly create and manage proprietary networks through the proprietary network console. After a proprietary network is created, some cloud service systems automatically create a router and routing table for it.

4. Scalable

Users can create different subnets and deploy different services in a proprietary network. In addition, a VPC can be connected to a local data center or other VPC to extend the network architecture.

The virtual switch of the CVM can build a proprietary network environment for users. The CVM connected to the virtual switch in the same cluster can communicate with each other in the private network. It supports unicast, multicast and broadcast communication, and the access speed is fast.
