  • サマリー

  • In this episode of podcast_v0.1, we dive into a surprising performance bottleneck lurking inside Kubernetes: the storage speed of etcd. We explore the research paper "Impact of etcd Deployment on Kubernetes, Istio, and Application Performance," where researchers show how slow storage can ripple through your entire cluster, hurting application performance in ways you might not expect. We’ll break down how Kubernetes orchestration depends on etcd, how service meshes like Istio amplify platform overhead, and why tuning your infrastructure matters just as much as tuning your code. Plus, we’ll touch on the researchers' open-source framework for reproducible performance testing in complex environments. Whether you're debugging 503 errors or chasing mysterious latency spikes, this episode will help you think beyond your app and into the platform itself.
