AWS Fargate provides a serverless container platform that allows developers to deploy and manage containerized workloads without provisioning or maintaining the underlying infrastructure. It integrates with Amazon Elastic Container Service (ECS) and Amazon Elastic Kubernetes Service (EKS), enabling users to focus on delivering business value instead of managing capacity planning and operational issues. Fargate pricing is based on usage, making it easier for developers to manage costs. To monitor Fargate clusters, users can track key metrics such as memory utilization, CPU utilization, and cluster state metrics. These metrics provide visibility into the performance, activity, and resource utilization of the Fargate-backed cluster, helping developers optimize their workloads and reduce costs. By leveraging these metrics and tools, developers can gain a deeper understanding of their Fargate clusters and improve their overall efficiency and reliability.
