How did John ensure the Kubernetes clusters could handle unprecedented traffic growth?
assistant
To handle unprecedented traffic growth, John implemented Horizontal Pod Autoscalers (HPA) and Cluster Autoscaler for dynamic scaling. He also optimized load balancer configurations and conducted chaos engineering exercises to validate the system's resilience. These measures ensured the clusters could scale efficiently under any conditions. John ensured the clusters could handle traffic growth through dynamic scaling, load balancing, and resilience testing.
