Azure VPN gateways are basically your core routers and firewalls within your Azure environment.
An Azure gateway can serve different purposes:
- Internet gateway
- Site-to-site VPN gateway
- Point-to-site VPN gateway
- ExpressRoute gateway
- VNet-to-VNet gateway
We won't be able to cover the deployments of point-to-site VPN gateways in this book but you can find a detailed guide in the Microsoft documentation at https://azure.microsoft.com/en-us/documentation/articles/vpn-gateway-howto-point-to-site-rm-ps/.
The following screenshot shows the Azure service you need to look for when you want to implement an Azure VPN gateway:
Every VNet can have at least one VPN gateway. VPN gateways are available in different service offerings with different features and available services.
