Azure VPN Gateway Overview followed by the next lecture with DEMO
A VPN gateway is a specific type of virtual network gateway that is used to send encrypted traffic between an Azure virtual network and an on-premises location over the public Internet. You can also use a VPN gateway to send encrypted traffic between Azure virtual networks over the Microsoft network. Each virtual network can have only one VPN gateway. However, you can create multiple connections to the same VPN gateway. When you create multiple connections to the same VPN gateway, all VPN tunnels share the available gateway bandwidth.
What is a virtual network gateway?
A virtual network gateway is composed of two or more VMs that are deployed to a specific subnet you create called the gateway subnet. Virtual network gateway VMs contain routing tables and run specific gateway services. These VMs are created when you create a virtual network gateway. You can't directly configure the VMs that are part of the virtual network gateway.
When you configure a virtual network gateway, you configure a setting that specifies the gateway type. The gateway type determines how the virtual network gateway will be used and the actions that the gateway takes. The gateway type 'Vpn' specifies that the type of virtual network gateway created is a 'VPN gateway'. This distinguishes it from an ExpressRoute gateway, which uses a different gateway type. A virtual network can have two virtual network gateways; one VPN gateway and one ExpressRoute gateway.
Creating a virtual network gateway can take up to 45 minutes to complete. When you create a virtual network gateway, gateway VMs are deployed to the gateway subnet and configured with the settings that you specify. After you create a VPN gateway, you can create an IPsec/IKE VPN tunnel connection between that VPN gateway and another VPN gateway (VNet-to-VNet), or create a cross-premises IPsec/IKE VPN tunnel connection between the VPN gateway and an on-premises VPN device (Site-to-Site). You can also create a Point-to-Site VPN connection (VPN over OpenVPN, IKEv2, or SSTP), which lets you connect to your virtual network from a remote location, such as from a conference or from home
It's important to know that there are different configurations available for VPN gateway connections. You need to determine which configuration best fits your needs. For example, Point-to-Site, Site-to-Site, and coexisting ExpressRoute/Site-to-Site connections all have different instructions and configuration requirements.
Data transfer costs
Data transfer costs are calculated based on egress traffic from the source virtual network gateway.
If you are sending traffic to your on-premises VPN device, it will be charged with the Internet egress data transfer rate.
If you are sending traffic between virtual networks in different regions, the pricing is based on the region.
If you are sending traffic only between virtual networks that are in the same region, there are no data costs. Traffic between VNets in the same region is free.
