Editor to share with you what the vpc network means, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Vpc network refers to the private network and is a concept defined for the basic network of the public cloud. Vpc is a self-defined logically isolated network space on the public cloud and a network space that we can customize. Similar to the traditional network we run in the data center, what is hosted in the VPC is our server resources on the private cloud, such as CVM, load balancer and so on.

Private network (VPC)

Private network is a concept defined for the basic network (classical network) of the public cloud.

VPC (Virtual Private Cloud) is a customized logically isolated network space on the public cloud, and it is a network space that we can customize. Similar to the traditional network we run in the data center, what is hosted in the VPC is our server resources on the private cloud, such as CVM, load balancer, cloud database, etc. We can customize network segment division, IP address and routing policy, and achieve multi-layer security protection through security groups and network ACL. At the same time, you can also connect VPC to our data center through VPN or direct connect, and deploy hybrid cloud flexibly.

VPC is mainly a network-level function, and its purpose is to enable us to build an isolated virtual network environment on the cloud platform where we can manage configurations and policies, so as to further improve the security of our resources in the AWS environment. We can manage our own subnet structure, IP address range and allocation method, network routing strategy and so on in the VPC environment. Because we can control and isolate the resources in VPC, this is like a private cloud computing environment for us.

We use VPC and other related cloud services to integrate an enterprise's own data center with its environment on the cloud to form a hybrid cloud architecture.

Benefits of using private network

1) flexible deployment: custom network partition, routing rules, configuration implementation take effect immediately

2) Security isolation: 100% logically isolated cyberspace, my territory listens to me

3) Rich access: support public network VPN access and direct connect access

4) access control: accurate to the port network control to meet the security requirements of financial, government and enterprises

Application scenario

Safety network

Through the VPC network to build a network with strict security access control, while taking into account the security isolation of core data and effective access from the public network. Users can deploy the core server or database system that handles core data and services in a subnet that cannot be accessed by the public network, and deploy the web server for public network access in another subnet environment, and set the subnet to connect with the public network. In the VPC network, users can access the core data and business servers through the access control between subnets, which not only ensures the security and controllability of the core data, but also meets the access needs of the public network.

Hybrid cloud network

Establish a secure and efficient network connection through tunneling or VPN services provided by the VPC network. Deploy Web applications in VPC to obtain additional privacy protection and security through distributed firewalls. Users can create firewall rules. Make Web applications refuse access to Internet while responding to requests such as HTTP/HTTPS, so as to consolidate the security of the website, thus realizing the interconnection between applications deployed on the public cloud and businesses deployed in their own data centers, and building a hybrid cloud architecture.

Hosting website

Through the NAT function of destination address provided by VPC network, secure access to the Internet without EIP is realized.

Solve the network bottleneck

Tunnel / VPN/ Direct Connect service provided through VPC network makes it easy to deploy enterprise applications in the cloud.

Disaster recovery

Tunnel / VPN/ dedicated line service provided through VPC network is convenient to build a disaster environment.

The difference between VPC and basic network (classical network)

Classic network: all users on the public cloud share a common network resource pool, and there is no logical isolation between users. Users' intranet IP is uniformly assigned by the system, and the same intranet IP cannot be assigned to different users.

VPC: creates a logically isolated virtual network space for users on the public cloud. In VPC, users can customize network segment division, IP address and routing policy, and security can provide access control for network ACL and security groups. Therefore, VPC has higher flexibility and security.

Architecture comparison between Classic Network and VPC:

By comparison, we can see that VPC has obvious advantages. Through VPC, users can customize network segment division, IP address and routing policy; in terms of security, VPC can provide access control for network ACL and security groups, and VPC has higher flexibility and security. It can be used in business that requires high security isolation, hosting multi-layer web applications, elastic hybrid cloud deployment and other use scenarios, and meets the strong regulatory and data security requirements of finance, government, enterprise and other industries.

Basic network and private network are two network modes on the cloud. Cloud resources that users do not label as VPC network are deployed in the basic network.
