VPN Overview

VPN(Virtual Private Network) is a network access service based on Internet and a method for the implementation of hybrid cloud solutions. JD Cloud provides IPsec-based Site-To-Site VPN to realize networking communication based on intranet address between data centers/offices and JD Cloud VPC by establishment of encryption tunnels, and customers can carry out application migration to JD Cloud Onboarding, deploy hybrid cloud based on the encryption tunnel and ensure data security during the communication process.

VPN-related products include: Border Gateway, Customer Gateway, VPN Connection and VPN Tunnel. Where: VPN Gateway on cloud is carried by Border Gateway, Customer Gateway is the logical representation of client VPN devices on cloud, VPN Connection is established by customers based on Border Gateway and Customer Gateway, and VPN Connection represents an integration of all VPN Tunnels established between a group of cloud public IP and client public IP, achieving high availability of tunnel level. Meanwhile, multiple VPN connections can be established between cloud and client by customers so as to achieve high availability of connection level.

  In order to achieve automatic fault switchover among multiple tunnels under VPN connection, you are strongly recommended to use BGP dynamic route for route setting. Because BGP route is supported by Border Gateway and route transmission is supported by VPC route table, the routing clauses can be adjusted dynamically so that automatic removal of routes from fault link can be achieved.
