He worked with both Azure Kubernetes Service (AKS) and Amazon Elastic Kubernetes Service (EKS), indicating experience with multi-cloud environments. For autoscaling, he implemented Horizontal Pod Autoscalers (HPA) and Cluster Autoscaler. Monitoring was done using Datadog for real-time tracking of cluster health, node utilization, and application performance. For disaster recovery and backup, he mentioned using tools like Velero for persistent volume backups. Load balancers were also part of his toolkit to distribute traffic evenly. John used a combination of AKS and EKS for cluster management, implemented HPA and Cluster Autoscaler for dynamic scaling, utilized Datadog for monitoring, and employed tools like Velero for disaster recovery, alongside custom load balancing solutions.
