You manage a highly distributed, hybrid- and multi-cloud IT environment and your developers rely heavily on Prometheus for their workflows. You need a cloud-based, highly scalable, low- maintenance enterprise solution that supports Prometheus Query Language (PromQL) queries, quick metric viewing, and efficient issue diagnosis. What should you do?

Google Cloud Managed Service for Prometheus is a fully managed, multi-cloud, cross-project solution that is built on the same globally scalable infrastructure as other Google services. It is designed to be a drop-in replacement for standard Prometheus, supporting PromQL for queries and alerts. This addresses the need for a low-maintenance, highly scalable, enterprise-grade solution that integrates seamlessly with existing Prometheus workflows. It allows developers to continue using their familiar tools while offloading the operational burden of managing and scaling the monitoring infrastructure.

A. Deploying a Prometheus operator is a self-managed approach, which contradicts the requirement for a low-maintenance, cloud-based enterprise solution.
B. Building a custom SaaS solution is a significant engineering effort, which is the opposite of a low-maintenance, ready-to-use solution.
D. While Cloud Monitoring provides a single pane of glass, Managed Service for Prometheus is the specific service designed for native Prometheus compatibility and PromQL support.
