Typical Application Scenarios

A VPC provides an isolated virtual network for ECSs. You can configure and manage the network as required.

  • If your ECSs do not need to access the Internet or need to access the Internet using a specified IP address with limited bandwidth on the default network segment, for example, the ECSs functioning as the database or server nodes for deploying a website, you can configure a VPC for the ECSs by following the instructions described in Configuring a VPC for ECSs That Do Not Require Internet Access.
  • If your ECSs need to access the Internet, you can configure EIPs for them. For example, the ECSs functioning as the service nodes for deploying a website need to be accessed by users over the Internet. Then, you can configure a VPC for these ECSs by following the instructions provided in Configuring a VPC for ECSs That Access the Internet Using EIPs.
  • If you need to access ECSs in a VPC over the Internet to perform maintenance operations, you can configure a VPN. For example, a website administrator needs to use a VPN to access ECSs functioning as service nodes in the VPC over the Internet. Then, you can configure a VPC for these ECSs by following the instructions provided in Configuring a VPC for ECSs That Access the Internet Through a VPN.
