Kubernetes Under Fire: Igniting Performance and Burning Through Bottlenecks with Kube-Burner
Sai Sindhur Malleni, Vishnu Vardhan Reddy Challa

What happens when your Kubernetes cluster is pushed to its absolute limits? Does it gracefully scale to meet demand, or does it buckle under pressure? In this session, we’ll dive deep into Kube-burner, the only CNCF Sandbox project laser-focused on performance and scalability testing. Designed to push Kubernetes clusters to their breaking point, Kube-burner is the ultimate tool for validating scalability, and ensuring your infrastructure can handle real-world stress. Through real-world case studies, we’ll explore how Kube-burner’s trio of superpowers—benchmark orchestration, precise measurements, and rock-solid observability—can uncover performance regressions, validate cluster stability, and ensure your infrastructure is ready for the demands of modern workloads.

Whether you’re a platform engineer, SRE, or Kubernetes enthusiast, this session will equip you with the knowledge to use Kube-burner to set your Kubernetes benchmarks on fire—and ensure your clusters can handle the heat.
