Azure VPNs

As the network continues to grow, there might come a time when we need to connect the Azure VNet to our on-premise location. A VPN gateway is a type of VNet gateway that can encrypt the traffic between a VNet and our on-premise network and remote clients. Each VNet can only have one VPN gateway, but multiple connections can be built on the same VPN gateway.

More information about Azure VPN gateways can be found at this link https://docs.microsoft.com/en-us/azure/vpn-gateway/.

VPN gateways are actually virtual machines themselves, configured with encryption and routing services, but cannot be directly configured by the user. Azure provides a list of SKUs based on the type of tunnel, number of concurrent connections, and total throughput (https://docs.microsoft.com/en-us/azure/vpn-gateway/vpn-gateway-about-vpn-gateway-settings#gwsku):
