Azure Application Gateway is a web traffic load balancer that enables you to manage traffic to your web applications. Traditional load balancers operate at the transport layer (OSI layer 4 - TCP and UDP) and route traffic based on source IP address and port, to a destination IP address and port.
In Altinn 3 we use Application gateways in front of Azure Loadbalancers.

We use Traefik as ingress controller in the different Kubernetes Clusters.
We use Express route for high performence networking between our Altinn 3 platform and the on-premise Altinn 2 platform.
