Grafana Cloud is a composable observability platform that integrates metrics, logs, and traces with Grafana. It allows customers to leverage the best open source observability software โ including Prometheus, Mimir, Loki, and Tempo โ without the overhead of installing, maintaining and scaling their own observability stack. The Databases team owns the telemetry databases that are Mimir for metrics , Loki for logs , Tempo for traces , and Pyroscope for profiles . The databases are OSS projects that we also offer as a Cloud service supporting Grafana Cloud, and as an on-premise solution. They are multi-tenant distributed systems implemented in Go and running on Kubernetes across all major Cloud service providers (GCP, Azure, AWS).
