At NVIDIA, we operate a large fleet of GPU Clusters that run Gaming and AI/ML workloads. As we expand, ensuring that we scale safely and efficiently becomes a critical challenge. Enter KWOK(Kubernetes Without Kubelet), our secret weapon for stress-testing new features before they hit production. This talk will dive into how we integrate KWOK into our development pipeline, showcasing how it's helped us maintain stability while rapidly innovating. 1. Identifying resource utilization boundaries: Demonstrate how KWOK has helped us evaluate the resource limits that need to be set on service pods so they can operate within safe boundaries. 2. Code optimization insights: Share examples of how KWOK has helped optimize our automation tools, significantly reducing their memory footprint. 3. Performance testing at scale: Illustrate how KWOK enables us to simulate large-scale environments, allowing us to identify potential bottlenecks and optimize system performance before production deployment.
