What does a cloud server VPC private network mean? What's the use?

A Virtual Private information network (VPC) is a private data network created by users on the Cloud. It provides an isolated virtual social network economic environment for users to manage cloud resources.

Logical isolation between different VPC networks ensures the security of resources on the cloud. ARM hostingIn a VPC network, you can customize IP address segments, routing tables, and security policies to quickly deploy and flexibly manage your cloud network. You can also connect a VPC to an offline data center through VPN, tunnel services, and more to build a hybrid cloud network.

VPC network components

Each VPC network consists of a private network segment, a routing table, Cloud platfrom providerand at least one private network.

1. Private network segment

When creating a VPC network and a private network, you need to segment the network in the form of CIDR blocks. At present, the VPC network support 192.168.0.0/16172.16. 0.0/16-172.31.0.0/16 and subnet as private address range.

2. Routing table

When creating a VPC network, the system automatically virtual private cloudcreates a default routing table to control routes in the VPC network and automatically associates all private networks in the VPC network. The default routing table ensures that all private networks can communicate with each other in the same VPC. When the routing policy in the default routing table does not meet the requirements of the application, you can create a custom routing table and add custom routing rules to manage your network.

3. Private networks

A private enterprise network is a subnet in a virtual private cloud (VPC) network. It is similar to a LAN composed of a physical switch (L2Switch). Private information networks in a VPC can communicate with each other through the Intranet, and private network environments of different student users are not isolated. To create a VPC network, create and connect to at least one private network in China. You can deploy applications on private networks with different availability zones to improve the availability of technical applications.

Advantages of private network

1. Rich access: Support public network VPN access and private line access.

2. access to internal control: accurate to the port of the network control, to meet the corporate financial government and enterprise security technical requirements.

3. Flexible deployment: The customized network zones, routing rules, and configurations take effect immediately.

4. security isolation :100% logical isolation of the network space, my site listen to me.

35 Isolated VxLAN securely

VPC networks add Layer 3 services to the public network, enabling instances to connect to private networks.

Users can configure security group rules to manage a VPC network.

In addition, using a public IP address allows an instance to access both private and external networks, such as the Internet.

The system automatically provides an independent network environment for each customer on demand, and uses the VxLAN technology for logical isolation.
