stio uses sidecar proxies to capture traffic, and where possible, automatically program the networking layer to route traffic through those proxies without any changes to the deployed application code. In Kubernetes, the proxies are injected into pods and traffic is captured by programming iptables rules. Once the sidecar proxies are injected and traffic routing is programmed, Istio is able to mediate all traffic. This principle also applies to performance. When applying Istio to a deployment, operators sho
