This article explains how AWS DevOps Agent uses multi-agent reasoning and architectural topology to investigate incidents and find root causes efficiently.

• Multi-agent architecture decomposes incident operations into specialized capabilities optimized for different priorities
• Topology graph provides architectural foundation showing resource relationships, runtime communication, and deployment lineage
• Triage correlates related alarms and enriches investigations with context at machine speed
• Investigation generates multiple competing hypotheses simultaneously and validates with supporting and counter-evidence
• Mitigation generates safe remediation plans with rollback procedures; execution remains with operators
• Prevention clusters past incidents by root cause to identify patterns and recommend proactive improvements
• Investigation journal provides immutable audit trail of reasoning across incident lifecycle
• Agent Space isolates topology graphs, investigation history, and integrations per team or service

AWS DevOps Agent creates an operational flywheel where investigation findings feed prevention recommendations, reducing incident frequency and resolution time over time.
