Amazon Elastic Container Service (ECS) is a container orchestration service that enables efficient deployment and modernization of applications by migrating them to a containerized environment. Datadog's ECS Explorer provides comprehensive monitoring, offering insights into clusters, services, tasks, and infrastructure. It helps track deployments, scaling activity, and troubleshoot issues related to tasks, containers, and events. The ECS Explorer also offers visibility into task definitions, enabling users to inspect and optimize their tasks and containers. Additionally, it provides context for infrastructure metrics, allowing users to monitor resource utilization and identify potential waste or cost optimization opportunities.
