-Set up monitoring for Kubernetes clusters and configured Prometheus and Grafana to collect and store metrics, providing more visibility into resources and decreasing response time in case of downtime.-Implemented an autoscaling group with a blend of self-managed nodes, utilizing a mix of spot and on-demand instances. This strategic setup significantly enhanced the EKS cluster's reliability, leading to a remarkable 34% reduction in EC2 instance utilization costs.-Created a resilient, secure, and highly available EKS cluster on AWS using Terraform as the IaC tool. This approach automated the setup, elevating overall efficiency.-Effectively deployed a cluster autoscaler for EKS, guaranteeing optimal resource usage and seamless scaling to manage unexpected traffic surges.-Set up monitoring for Kubernetes clusters and configured Prometheus and Grafana to collect and store metrics, providing more visibility into resources and decreasing response time in case of downtime. -Implemented an autoscaling group with a blend of self-managed nodes, utilizing a mix of spot and on-demand instances.
