AKS have multiple options to manage the egress or outbound traffic. These options are Load Balancer, NAT Gateway and User Defined Routing (UDR). In this lightboard session, I explain all these modes available in #Azure #Kubernetes #AKS.
The outbound type Load Balancer is the default mode and should fit for most cases.
However, if we might have the issue of SNAT port exhaustion, then we should use the NAT Gateway mode.
And for enterprises using Landing Zone, Hub & Spoke architecture and wants to control and filter the AKS egress traffic, they should use the User Defined Routing (UDR) mode.
With this latter mode, we should pay attention to the asymmetric routing for ingress traffic.
