Overview

Azure VPN Gateway connects on-premises networks to Azure through Site-to-Site VPNs in a similar way that you set up and connect to a remote branch office. The connectivity is secure and uses the industry-standard protocols Internet Protocol Security (IPsec) and Internet Key Exchange (IKE).

VPN gateways provide secure connectivity between multiple sites, such as on-premises data centers, Google Cloud Virtual Private Cloud (VPC) networks, and Google Cloud VMware Engine private clouds. Traffic is encrypted because the VPN connections traverse the internet. Each VPN gateway can support multiple connections.

There are four types of VPNs that can be used with Microsoft Azure cloud computing:

• Point-to-site VPN
• Site-to-site VPN
• Multi-Site VPN
• ExpressRoute
