What tools and techniques did John use to optimize resource allocation in the Kubernetes clusters?
assistant
John used Horizontal Pod Autoscalers (HPA) and Cluster Autoscaler to optimize resource allocation dynamically. He also implemented resource requests and limits, affinity rules, and cost optimization techniques. These tools and techniques ensured efficient use of resources, preventing both over-provisioning and underutilization while maintaining high performance.
