Autoscaling Amazon EKS services based on custom Prometheus metrics using CloudWatch Container Insights
Introduction In a Kubernetes cluster, the Horizontal Pod Autoscaler can automatically scale the number of Pods in a Deployment based on observed CPU utilization and memory usage. The autoscaler depends on the Kubernetes metrics server, which collects resource metrics from Kubelets and exposes them in Kubernetes API server through Metrics API. The metrics server has […]
Load balancing Amazon ECS services with a Kubernetes Ingress Controller style approach
Introduction A common approach to traffic routing in a Kubernetes cluster is to employ an Ingress Controller. The Ingress Controller is an application that runs in a cluster in conjunction with a load balancer and routes incoming HTTP/HTTPS/TCP requests to proxied servers according to routing rules specified in Ingress resources. When deploying to either a […]
