John implemented HPA to dynamically adjust the number of pod replicas based on CPU and memory usage. This ensured that the clusters could handle traffic spikes efficiently without manual intervention, contributing to the 99.99% uptime. Horizontal Pod Autoscaler (HPA) was critical in John Mosquera's strategy, enabling dynamic scaling of pod replicas to handle traffic spikes and maintain high uptime.
