How did John Mosquera achieve 99.99% uptime for large-scale Kubernetes clusters (AKS and EKS)?
assistant
The client's previous Kubernetes setup faced scalability issues and performance inconsistencies. John Mosquera began by evaluating the existing architecture and identifying inefficiencies. He then implemented Horizontal Pod Autoscalers (HPA) and Cluster Autoscaler to dynamically adjust resources based on traffic. Load balancer configurations were fine-tuned for even traffic distribution. Proactive monitoring with Datadog and custom alerts helped identify and resolve issues promptly. Disaster recovery plans, including cross-region replication and backup schedules, were established. Regular chaos engineering exercises validated system robustness. John also collaborated with the client's SRE team to refine operational practices and provide training. John Mosquera achieved 99.99% uptime by redesigning the cluster architecture, implementing advanced autoscaling, fine-tuning load balancers, and establishing proactive monitoring and disaster recovery plans.
