Our review
Pros	PromQL supports selecting and aggregating multidimensional time series. Service discovery and HTTP scraping support dynamic Kubernetes environments. Alerting rules, Alertmanager, federation, and remote storage extend monitoring.	Tracks CPU, memory, disk, and network metrics across container workloads. Combines performance logs, CloudWatch alarms, and restart-failure diagnostics. Offers cluster-, service-, task-, and container-level observability modes.
Cons	Local storage is single-node rather than horizontally scalable. Focuses on metrics rather than logs or distributed tracing. Effective deployments may require exporters and connected ecosystem components.	No free plan; pricing is usage-based and varies by AWS Region and mode. Its supported environments are centered on AWS and AWS services. Support channels listed are documentation only.
Our verdict	Prometheus is an open-source monitoring and alerting toolkit for collecting numeric metrics and storing them as timestamped time-series data with labels. It is suited to infrastructure, application, and service monitoring, particularly in… Read the review →	For teams monitoring container workloads in AWS, Amazon CloudWatch Container Insights collects, aggregates, and summarizes metrics and logs from applications and microservices.
