Docker vs. Containerd Revisited: Stress-Testing Kubernetes Distributions in the Cloud

In this episode of podcast_v0.1, we dive into a fresh performance study that pits Docker and Containerd head-to-head inside a modern Kubernetes environment. We break down the paper "Kubernetes in Action: Exploring the Performance of Kubernetes Distributions in the Cloud," where researchers benchmark Kubernetes setups under extreme load, using real serverless workloads and breakpoint testing to find where systems actually start to fail. From container runtimes to lightweight Kubernetes distributions like K3s, MicroK8s, and K0s, the study reveals how virtualization layers, runtime choices, and cluster architectures impact resilience and performance. We explore why simply trusting defaults might not be enough—and why understanding system bottlenecks and failure modes matters more than ever.
