Most enterprises in 2026 still alert on static thresholds while operating systems too complex for any human to triage. AIOps closes the gap with adaptive anomaly detection, event correlation that collapses storms into incidents, automated root cause analysis, and autonomous remediation for known patterns. This guide covers what AIOps actually does in production, the leading platforms (Dynatrace Davis, Datadog Bits AI, PagerDuty AIOps, Moogsoft, BigPanda, Splunk ITSI, New Relic AI), the reference architecture for inserting AI into an existing observability stack, the maturity model, the common failure modes, and how AIOps integrates with AI workload observability.
