Building an end-to-end agentic SRE using AWS DevOps Agent

This article demonstrates building an end-to-end agentic SRE solution using AWS DevOps Agent for autonomous incident investigation and resolution.

• AWS DevOps Agent autonomously investigates incidents, identifies root causes, and recommends mitigation plans
• Agent Spaces define investigation scope with integrated CloudWatch, Splunk, GitHub, and Slack access
• Webhook integration enables automated incident triggers from CloudWatch alarms via EventBridge and Lambda
• Splunk MCP integration provides centralized log aggregation and analysis capabilities
• DevOps Agent Skills guide investigations using Markdown-based runbooks and documentation
• Mitigation plans include four phases: Prepare, Pre-Validate, Apply, and Post-Validate
• Agent-ready specs enable handoff to coding agents like Kiro for automated fix implementation
• Multi-account architecture separates demo application, Splunk, and DevOps Agent responsibilities

This solution shifts incident response from reactive firefighting to autonomous resolution, reducing MTTR while freeing engineers for innovation.
