Tracing failures across Terraform state boundaries with AWS DevOps Agent

This article demonstrates how AWS DevOps Agent traces failures that cross Terraform state boundaries, helping teams identify root causes when symptoms appear in one stack but originate in another.

• AWS DevOps Agent correlates alarms and maps dependency chains across Terraform state boundaries to find root causes
• Sample scenario: infrastructure team's security group change blocks Lambda-to-DynamoDB connectivity, causing timeouts in application team's stack
• Agent analyzes CloudTrail, VPC Flow Logs, and metrics to distinguish network issues from database or IAM problems
• Mitigation spec from agent feeds into Kiro to generate reviewed Terraform fixes automatically
• Three independent stacks (networking, compute, data-monitoring) demonstrate real team ownership patterns
• Agent discovers resources and builds topology to understand environment before investigating incidents

AWS DevOps Agent bridges operational visibility gaps created by Terraform state separation, enabling cross-team incident resolution without manual log-diving across stack boundaries.
