Application Scenarios

Application Scenarios

Secure and Isolated Network Environment

The VPC enables you to deploy a network environment that is isolated from the Internet for cloud servers, such as those that function as database nodes or server nodes when you build a website.

You can place multi-tier web applications into different security zones, and configure access control rules for each security zone as required. For example, you can create two VPCs, add web servers to one VPC, and add database servers to the other. Then, you can create security groups and firewalls for the two VPCs and configure inbound and outbound rules so that the web servers can communicate with the Internet while the database servers cannot communicate with the Internet. The purpose is to achieve security protection on database servers, meeting high security requirements. You can use a VPC peering connection to connect the two VPCs so that the web servers can communicate with the database servers.

Universal Web Applications

You can deploy basic web applications in a VPC.

You can use an EIP and the NAT gatewaySNAT function to let web applications communicate with the Internet. You can use security groups and virtual firewalls to perform access control, achieving security protection on web applications. To handle traffic bursts, you can use elastic load balancers.

Extending Your Corporate Network into the Cloud

You can use a VPN connection or a direct connection to connect a VPC to your local data center.

You can deploy applications in the cloud and deploy database servers in your local data center. Resources for applications in the cloud are highly scalable. You can use a VPN connection or a direct connection to connect a VPC to your local data center. This reduces IT O&M costs, protects enterprise core data from being leaked, and makes building a hybrid cloud architecture more convenient.
