How It Works

• Infrastructure deploys with intentional misconfigurations
• Incident tickets describe symptoms — you find the fix
• Diagnose issues by SSHing into VMs through a bastion host
• Fix issues from your local machine using cloud provider CLI (az, aws, gcloud)
• Validate fixes from your local machine — the script tests connectivity via SSH
