Application Scenarios

Application Scenarios

This section describes typical application scenarios of VPC.

Universal web applications

You can host basic web applications and simple websites in a VPC and use the VPC as a common network. You can also create a subnet in the VPC and add instances to the subnet. In addition, you can add security group rules to control inbound or outbound traffic for web servers to ensure website security.

  • Universal web applications

    You can host basic web applications and simple websites in a VPC and use the VPC as a common network. You can also create a subnet in the VPC, add instances to the subnet, and then assign EIPs to the instances to enable the instances to communicate with the Internet for running web applications on the instances. In addition, you can add security group rules to control inbound or outbound traffic for web servers to ensure website security.

  • Security-demanding services

    You can place multi-tier web applications into different security domains, and configure access control rules for each security domain as required. For example, you can create two VPCs and add the web servers and database servers to different VPCs. You can add inbound or outbound rules for a security group and specify that the VPC to which the web servers belong allows access from the Internet, but the VPC to which the database servers belong allows only internal access. This ensures database server security, meeting high security requirements. You can also create a VPC peering connection between the two VPCs to allow the communication between web servers and database servers.

  • Extending your corporate network into the cloud

    You can connect a VPC to your private cloud using a VPN. With the VPN between the VPC and your traditional data center, you can easily use the instances and block storage resources. Applications can be migrated to the cloud and additional web servers can be created to increase the computing capacity on a network. In this way, a hybrid cloud is built, which reduces IT O&M costs and protects enterprise core data from being leaked. VPCs can be created across AZs, thereby ensuring high availability of e-commerce systems.
