Enterprise Observability at Fixed Cost: The Self-Hosted LGTM Stack

As organizations scale, per-metric pricing from managed platforms like Datadog and New Relic grows prohibitively expensive, driving interest in self-hosted alternatives. The LGTM stack—combining Prometheus, Grafana, Tempo, and Loki—delivers enterprise-grade observability, DORA metrics, and SLO frameworks at fixed cost. Beyond economics, self-hosting ensures data sovereignty, eliminates vendor lock-in, and builds transferable technical knowledge.
