How did John Mosquera optimize resource allocation in the Kubernetes clusters?
assistant
John used HPA to dynamically adjust pod replicas based on CPU and memory metrics and Cluster Autoscaler to add or remove nodes as needed. This approach optimized resource allocation, preventing over-provisioning and ensuring efficient scaling during traffic spikes. John Mosquera optimized resource allocation by implementing HPA and Cluster Autoscaler, ensuring efficient scaling and preventing resource wastage in the Kubernetes clusters.
