The Challenge

Where It Started

Built a Zero-Touch operations bot — Prometheus detects anomalies, N8N triggers AWS Lambda to restart services or scale pods, and Slack notifies the team instantly.

Problems
  • On-call engineers manually restarting failed services at all hours
  • Average incident response time was 20+ minutes
  • No automated scaling response to sustained load spikes
  • Alerts went unnoticed until customers reported issues
Our Solution
  • Prometheus anomaly detection triggering N8N workflows instantly
  • N8N decision logic routing remediation automatically
  • AWS Lambda functions for automated service restarts
  • Slack real-time alerts with full incident context

Implementation

How We Delivered It

Week 1
Monitoring & Alert Rules
Configured Prometheus alerting rules for CPU, memory, pod crashes and error-rate anomalies across the cluster.
Week 2
N8N Decision Workflows
Built N8N workflows to evaluate alert severity and route to the correct remediation action automatically.
Week 3
Lambda & K8s Auto-Remediation
Implemented Lambda functions and Kubernetes pod-scaling actions triggered directly by N8N on incident detection.
Week 4
Slack Alerting & Handover
Wired up real-time Slack notifications with full incident context and handed over the self-healing system.

Results

The Impact We Delivered

0
Manual Incident Response
Routine incidents are now resolved without any human intervention.
<30s
Auto-Recovery Time
From anomaly detection to automated fix in under 30 seconds.
24/7
Autonomous Monitoring
The system watches, decides and remediates around the clock.
100%
Automated Remediation
Every detected anomaly triggers a fully automated recovery workflow.
"Our on-call rotation used to dread 2am pages. Now the system fixes itself before anyone even wakes up — it’s the closest thing to magic we’ve seen in ops."
