Figure 1 shows three panels, each of an Azure region that consists of 3 availability zones. Panel 1 shows that within each Azure region is a virtual network that contains a sing subnet. A virtual machine scale set consists of multiple virtual machines that are deployed across all three zones within the single subnet. NAT gateway is attached to the subnet from zone 1. In panel 2, zone 1 is down, which causes a loss of outbound connectivity across all three zones since all outbound connectivity goes through the zone 1 NAT gateway. Panel 3 shows that if zone 2 goes down, only outbound connectivity for virtual machines from that zone goes down. Outbound connectivity from zone 1 and 3 persists since NAT gateway is in a zone not impacted by the zone 2 outage.

Dive deep into NAT gateway’s SNAT port behavior

In our last blog, we examined a scenario on how network address translation (NAT) gateway mitigates connection failures happening at the same destination endpoint with its randomized source network address translation (SNAT) port selection and reuse timers. In addition to ... continue reading
