A fully managed version of Prometheus, the popular open-source metrics collection and alerting system, that stores and queries infrastructure metrics without you managing the Prometheus servers. Like outsourcing your building's entire alarm and sensor system to a professional monitoring company.
A platform team uses Amazon Managed Service for Prometheus to collect metrics from their 500-node Kubernetes cluster, storing billions of time-series data points and running PromQL queries for alerting — without managing any Prometheus servers, storage, or high-availability configuration.
All three major hyperscalers offer a managed Prometheus-compatible backend for storing/querying metrics and running PromQL, reducing the need to operate Prometheus servers. OCI supports Prometheus-style metrics ingestion and monitoring, but does not market a first-class standalone 'Managed Prometheus' product in the same way.
