At re:Invent 2025, Matt Garman announced AWS DevOps Agent, a frontier agent that resolves and proactively prevents incidents, continuously improving reliability and performance. As a member of the DevOps Agent team, we’ve focused heavily on making sure that the “incident response” capability of the DevOps Agent generates useful findings and observations. In particular, we’ve been working on making root cause analysis for native AWS applications accurate and performant. Under the hood, DevOps Agent has a multi-agent architecture where a lead agent acts as an incident commander: it understands the symptom, creates an investigation plan, and delegates individual tasks to specialized sub-agents when those tasks benefit from context compression.
