An Agentic LLM-based Architecture for Automated Anomaly Detection and Adaptive Remediation
Traditional cloud monitoring often relies on static remediation procedures that are difficult to adapt to dynamic and heterogeneous infrastructures. This paper proposes an agentic LLM-based architecture for adaptive remediation planning from confirmed cloud anomalies. The goal is not to replace anomaly detectors, but to transform confirmed anomaly events into structured, policy-constrained remediation artifacts suitable for human-supervised operational workflows.The proposed workflow combines anomaly intake, contextual validation, playbook retrieval, and constrained playbook generation through a message-driven Multi-Agent System. Retrieval-Augmented Generation is used to correlate current incidents with historical knowledge and existing procedures, while deterministic guardrails enforce schema validation, policy constraints, command allow/deny lists, critical-resource checks, and human approval for high-impact or previously unseen actions.A containerised Proof of Concept demonstrates that confirmed anomalies can be transformed into CACAO-compatible remediation drafts within operationally reasonable time bounds. The evaluation focuses on generating and validating remediation plans under explicit operational constraints, rather than on anomaly detection benchmarking or on production-scale autonomous execution.
