Amazon Elastic Kubernetes Service (EKS) is a managed Kubernetes platform by AWS that provides Kubernetes-as-a-service, automating the provisioning and management of infrastructure to ensure high availability across multiple availability zones. EKS integrates with AWS services like VPC, ELB, EBS, and EC2 or AWS Fargate to enhance network isolation, load balancing, persistent storage, and compute resource provisioning. Monitoring EKS clusters is crucial for maintaining application performance and identifying resource bottlenecks, focusing on metrics like resource utilization, pod availability, and cluster state, as well as AWS service metrics such as those from EC2 and EBS. The article emphasizes the importance of tracking events and metrics to ensure cluster health, offering insights into Kubernetes operations and AWS infrastructure performance, which are integral for capacity planning and troubleshooting. It also previews further guidance on collecting these metrics using Kubernetes tools and AWS CloudWatch in the next part of the series.
