Business Challenge

The Problem

Manual incident management caused 4-hour mean time to resolution, 200+ monthly incidents with alert fatigue, and 93.2% uptime (below SLA), resulting in customer churn, revenue loss, and burned-out on-call engineers working nights and weekends to keep systems running.

Slow Incident Response & Alert Fatigue

4-hour mean time to resolution (MTTR)

Incidents detected by Datadog manually triaged by on-call engineers - 30 min to acknowledge, 3.5 hours to resolve (SLA target: 1 hour MTTR)

200+ incidents per month

Mix of critical (15%), high (30%), medium (40%), low (15%) - all trigger PagerDuty alerts to on-call rotation (24 engineers)

2,400+ alerts per month

92% false positives or low-severity noise - engineers ignoring alerts, missing critical issues buried in noise (alert fatigue)

Downtime & Revenue Impact

93.2% platform uptime

SLA commits to 99.5% uptime - missing SLA 6 months in a row, customer SLA credits €340K/year, churn risk on 18% of customer base

€2.8M revenue at risk

18% of ARR (€85M × 18% = €15.3M) threatened by churn due to reliability issues - lost 12 enterprise customers in past year citing "too many outages"

42 hours downtime/year

Across 450 microservices - database crashes (28%), API timeouts (35%), deployment failures (22%), infrastructure issues (15%)

Manual Processes & Tribal Knowledge

80% manual remediation

Common fixes (restart service, scale replicas, clear cache, rollback deployment) done manually via kubectl, Azure CLI - no runbooks or automation

Knowledge in people's heads

"Ask Johan about payment service" culture - 5 senior engineers hold critical tribal knowledge, no documentation, new hires take 6 months to ramp up

No automatic escalation

Critical incidents manually escalated via Slack "war room" - 45 min average to assemble right team (database expert, network admin, product owner)

Engineer Burnout & Hiring Costs

38% on-call engineer turnover

On-call rotation (24 engineers) experiencing burnout - paged 8× per night on average, working weekends to fix incidents (industry avg: 18% turnover)

€480K annual hiring cost

Replacing 9 engineers/year at €110K avg salary + recruiting/training costs - burnout causing talent exodus, hard to hire replacements (6-month avg time-to-hire)

60 hours/week on-call load

Engineers spending 20 hours/week on incident response (50% of time) instead of product development - feature velocity down 40% vs 2 years ago

Solution Architecture

Technspire deployed n8n on Azure to create 32 intelligent IT operations workflows that automate incident triage, intelligent alert routing with Azure OpenAI-powered severity classification, automatic remediation for common issues, and escalation management - reducing MTTR from 4 hours to 45 minutes while improving uptime to 97%.

1

n8n Platform on Azure Kubernetes Service (AKS)

Deployed n8n on Azure Kubernetes Service (AKS) for high availability and auto-scaling (3 replicas, horizontal pod autoscaling). PostgreSQL on Azure Database stores workflow execution history and incident tracking data. Azure Key Vault manages credentials for 18 integrated systems (PagerDuty, Datadog, Slack, Jira, Azure DevOps, GitHub, etc.). Azure Monitor tracks workflow performance and sends alerts if workflows fail.

Key Features: High availability (99.9% uptime), horizontal scaling (handle 10K alerts/hour), secure credential management, workflow execution monitoring

Architecture: 3 n8n pods (AKS), PostgreSQL (Azure Database), Azure Key Vault, Azure Monitor, Azure Application Insights

2

Intelligent Alert Triage & Routing (12 Workflows)

Created 12 alert triage workflows triggered by Datadog webhooks (APM, infrastructure, logs, synthetics). Workflows use Azure OpenAI GPT-4 to analyze alert context (error message, stack trace, service dependencies, recent deployments) and classify severity (P0 critical, P1 high, P2 medium, P3 low). Intelligent routing: P0 → page entire on-call team + create Slack war room, P1 → page primary on-call, P2 → create Jira ticket, P3 → log to database (no alert). Deduplication: Similar alerts within 15 min grouped into single incident (reduced 2,400 → 220 alerts/month, 91% reduction).

Workflows: Datadog APM → GPT-4 classify → route, Infrastructure alerts → triage → escalate, Log errors → analyze → assign, Synthetic monitors → validate → page

Result: 89% auto-triage accuracy, 91% alert noise reduction (2,400 → 220/month), 30 min → 2 min acknowledgement time

3

Automated Remediation & Self-Healing (8 Workflows)

Built 8 auto-remediation workflows for common incidents (80% of issues): (1) Restart Service - if health check fails 3×, restart AKS pod automatically, (2) Scale Replicas - if CPU >85%, scale from 3→6 replicas, (3) Clear Cache - if Redis memory >90%, flush LRU cache, (4) Rollback Deployment - if error rate spikes post-deploy, auto-rollback to previous version, (5) Database Connection Pool - if pool exhausted, increase max connections, (6) Certificate Renewal - renew SSL certs 7 days before expiry, (7) Disk Cleanup - delete old logs if disk >85% full, (8) DNS Propagation - refresh DNS cache if lookup failures spike.

Key Tech: n8n HTTP Request (kubectl API, Azure CLI), Datadog API (metrics), Slack API (notifications), runbook scripts (Bash, PowerShell)

Result: 68% of incidents auto-resolved (136/200 per month), 4h → 45min MTTR, 93.2% → 97% uptime

4

Escalation Management & War Room Automation (6 Workflows)

Created 6 escalation workflows for P0/P1 incidents that cannot be auto-resolved: (1) Assemble War Room - create Slack channel, invite on-call team + service owners + execs, (2) Stakeholder Notifications - notify customer success, post status page update, send email to affected customers, (3) Knowledge Retrieval - search Confluence runbooks, pull relevant past incidents from Jira, send to Slack, (4) Expert Finder - query GitHub commits to identify service owners, ping via Slack, (5) Incident Timeline - auto-generate timeline from Datadog events, deployments, alerts, Slack messages, (6) Post-Mortem - create Jira template with timeline, assign to service owner, schedule blameless post-mortem meeting.

Integrations: Slack, PagerDuty, Jira, Confluence, GitHub, Statuspage, Datadog, Calendly

Result: 45 min → 5 min to assemble war room, 100% post-mortems completed (vs 30% before), knowledge capture improved

5

Monitoring & Observability Workflows (4 Workflows)

Built 4 monitoring workflows for proactive issue detection: (1) Anomaly Detection - Azure ML model detects traffic/latency anomalies, triggers investigation workflow, (2) SLA Monitoring - track uptime per customer, send alerts if approaching SLA breach (99.5% threshold), (3) Cost Optimization - detect idle resources (AKS pods scaled to 0 traffic, unused storage), create tickets to decommission, (4) Security Scanning - daily vulnerability scans (Trivy for containers, Dependabot for code), create Jira tickets for CVEs, auto-patch low-risk vulnerabilities.

Key Tech: Azure ML (anomaly detection), Datadog API, Azure Cost Management, Trivy, Dependabot, Snyk, Jira API

Result: 12 production issues prevented (caught in monitoring before customer impact), €120K cloud cost savings from idle resource cleanup

6

ChatOps & Incident Commands (Slack Bot)

Created Slack bot powered by n8n for ChatOps (engineers trigger workflows via Slack commands): /incident status - show all active incidents with timelines, /restart [service] - restart AKS pod for service, /scale [service] [replicas] - scale service to N replicas, /rollback [service] - rollback to previous deployment, /runbook [service] - search Confluence for service runbook, /oncall - show who's on-call this week (PagerDuty integration). Engineers can also ask GPT-4 via Slack ("how do I restart payment service?") and bot executes workflow.

Key Tech: Slack slash commands, n8n webhook triggers, Azure OpenAI GPT-4 (natural language commands), kubectl API, Azure CLI

Result: 85% of manual tasks now done via Slack (vs logging into Azure Portal), 10 min → 30 sec for common operations
