With telemetry service provided by Istio, containerized application performance monitoring has never been easier. But what do you do with slow response time when you have application deploying at scale? Slow response time is just a symptom, the root causes might be incorrect CPU/Mem limit configuration, incorrect number of replicas, underlying infrastructure congestion, or, a combination of the above. The corresponding way to solve it could be vertical scale the container, horizontal scale the pod, or reschedule the pod to a different node. In this presentation, we are going to share our lesson and knowledge about managing containerized application performance by leveraging the telemetry information from Istio to assure the application SLA
