Introduction Topology Aware Routing (TAR) is a Kubernetes feature designed to keep traffic within the same availability zone (AZ). This can reduce cross-AZ traffic costs on cloud providers like AWS and GCP, where inter-AZ traffic incurs charges. Additionally, it can lower latency by keeping network requests local. However, TAR is not a silver bullet. While it helps optimize costs and performance, it strictly prohibits cross-zone traffic, regardless of the system’s health or workload distribution. This limitation can lead to unintended service disruptions. ...
