Hi Mateusz Labusek,
In Azure, you can deploy only one VPN gateway per virtual network, but that VPN gateway consists of multiple instances to ensure high availability.
The active/active model and other HA methods (like active/standby) refer to how the VPN gateway instances are configured within that single VPN gateway. In the active/active configuration, for example, the gateway runs two instances simultaneously, each with its own public IP address, which ensures continuous connectivity. These configurations are part of the VPN gateway's design to provide resiliency, not multiple separate gateways.
So, the active/active model and HA options apply to the VPN gateway itself, not separate VPN gateways.
