Term Kind Topic What it is
Invisible Resource Exhaustion Silent Limit, Unattributed Failure concept NAT & Egress A class of failure where a shared finite resource outside the application's view is exhausted, producing intermittent unexplained errors while every local metric looks healthy.
NAT Gateways tool NAT & Egress The component that lets private instances reach the internet, and one of the most reliably surprising line items on a cloud bill.
Port Exhaustion concept NAT & Egress Running out of available source ports for outbound connections through a NAT device, causing new connections to fail while everything appears healthy.
Source NAT SNAT, Masquerading concept NAT & Egress Rewriting the source address of outbound packets so that many private addresses share one public address, with a translation table mapping replies back.
