Natan Yellin deep dives into Kubernetes resource management, specifically focusing on CPU limits. He started by gauging the audience's familiarity with Kubernetes workloads and CPU limits, aiming to persuade them to reconsider their use of CPU limits. Natan made compelling arguments using practical examples, including a unique scenario involving 'Tinder for Socks'. He explained how Kubernetes' four key numbers (CPU request, CPU limit, memory request, and memory limit) influence resource allocation and cost optimization, and why CPU limits might not always be the best option.
