Virtual Private Network (VPN)

Definition

  • A virtual private network (VPN) is a secure, encrypted communication tunnel established between a remote user and a virtual private cloud (VPC)
  • This tunnel meets the industry standards and can seamlessly extend your data center to a VPC

Functions

  • Extending your data center to the cloud: If you want to build an enterprise hybrid cloud architecture, connecting your local data center to cloud resources using an encrypted tunnel over the Internet, create a VPN connection
  • Extending your applications to the cloud: You can use a VPN to connect a VPC to your data center, extending your data center to the VPC rapidly

Application Scenarios

  • Deploying a VPN to Connect a VPC to a Local Data Center: With the VPN between a VPC and your traditional data center, you can easily use the ECSs and block storage resources in the cloud
  • Deploying a VPN to Connect a VPC to Multiple Local Data Centers: With VPN between VPC and multiple traditional data centers, you can easily use ECSs and block storage resources in the cloud
  • Cross-Region Interconnection Between VPCs: In this scenario, a VPN tunnel is established between two VPCs in different regions to enable mutual access between the two VPCs
