What Is Virtual Private Network?

Overview

Virtual Private Network (VPN) establishes secure, reliable, and cost-effective encrypted connections between your on-premises network or data center and a virtual network on Huawei Cloud.

A VPN consists of a VPN gateway, a customer gateway, and one or more VPN connections.

  1. A VPN gateway provides an Internet egress for a VPC to connect to a customer gateway in your on-premises data center.
  2. A VPN connection connects a VPN gateway to a customer gateway through encrypted tunnels, enabling communication between a VPC and your on-premises data center. This helps quickly establish a secure hybrid cloud environment.

Components

VPN gateway: is a virtual gateway of a VPN on Huawei Cloud. It establishes secure private connections with a customer gateway in your on-premises network or data center.

Customer gateway: is a resource that provides information to Huawei Cloud about your customer gateway device, which can be a physical device or software application in your on-premises data center.

VPN connection: is a secure channel between a VPN gateway and a customer gateway. VPN connections use the Internet Key Exchange (IKE) and Internet Protocol Security (IPsec) protocols to encrypt the transmitted data.

Accessing the VPN Service

You can access the VPN service through the web-based management console.

If you have registered an account, log in to the management console and choose Networking > Virtual Private Network to log in to the VPN console.

If you do not have an account, register one first by referring to Preparations.
