2. Self-Healing Nginx

Base Role: geerlingguy.nginx
Downloads: 8M+ | Stars: 850+

What it does: Installs, configures, and manages Nginx web server.

ANSAI Enhancement: AI-powered analysis of 500 errors and automatic recovery.

# Standard Nginx deployment
- hosts: webservers
  roles:
    - role: geerlingguy.nginx
      nginx_vhosts:
        - server_name: "example.com"
          root: "/var/www/html"

# Add ANSAI intelligent monitoring
- hosts: webservers
  roles:
    - ansai.self_heal
  vars:
    monitored_services:
      - name: nginx
        port: 80
        critical: true
        ai_analysis_enabled: true
        log_analysis:
          error_log: /var/log/nginx/error.log
          access_log: /var/log/nginx/access.log

AI Analysis Example:

🤖 NGINX FAILURE ANALYSIS

ROOT CAUSE: 
Worker processes exhausted due to upstream timeout. PHP-FPM
not responding, causing all workers to block.

WHY IT FAILED:
• PHP-FPM pool exhausted (50/50 workers busy)
• Slow database queries (avg 12s response time)
• Nginx worker_processes = 4 (insufficient for load)

RECOMMENDED FIX:
1. Increase PHP-FPM pm.max_children from 50 to 100
2. Optimize slow queries (top 3 queries identified)
3. Increase nginx worker_processes to 8

PREVENTION:
Add upstream timeout (proxy_read_timeout 30s) to fail fast
instead of blocking workers.

3. PostgreSQL with Predictive Tuning

Base Role: geerlingguy.postgresql
Downloads: 2M+ | Stars: 450+

What it does: Installs and configures PostgreSQL database.

ANSAI Enhancement: AI-driven performance tuning and failure prediction.

  vars:
    monitored_services:
      - name: postgresql
        port: 5432
        critical: true
        ai_tuning_enabled: true
        metrics_collection:
          - cache_hit_ratio
          - active_connections
          - slow_queries

AI Tuning Example:

🤖 AI DATABASE TUNING RECOMMENDATIONS

CURRENT PERFORMANCE:
• Cache hit ratio: 87% (target: >95%)
• Active connections: 180/200 (90% utilization)
• Slow queries: 45/hour (queries >1s)

RECOMMENDED CONFIG CHANGES:
shared_buffers: 4GB → 8GB (you have 32GB RAM)
effective_cache_size: 8GB → 24GB
work_mem: 4MB → 16MB
maintenance_work_mem: 64MB → 512MB

EXPECTED IMPACT:
• Cache hit ratio: 87% → 96%
• Query performance: +40% faster
• Connection overhead: -25%

APPLY? [Y/n]

4. Prometheus + Grafana Monitoring with AI Insights

Base Roles: - cloudalchemy.prometheus by Cloud Alchemy - cloudalchemy.grafana

Downloads: 5M+ combined | Community: 200+ contributors

What they do: Deploy complete monitoring stack with Prometheus and Grafana.

# Deploy monitoring stack
- hosts: monitoring
  roles:
    - cloudalchemy.prometheus
    - cloudalchemy.grafana
    - ansai.ai_insights
  vars:
    prometheus_scrape_configs:
      - job_name: 'node'
        static_configs:
          - targets: ['localhost:9100']

    # ANSAI AI enhancement
    ansai_ai_analysis:
      enable_anomaly_detection: true
      alert_reduction: true  # AI reduces alert noise
      predictive_alerts: true

AI Alert Intelligence:

Traditional Alert Fatigue:

[12:01] CPU High (85%)
[12:02] Memory High (88%)
[12:03] Disk I/O High
[12:04] Network errors detected
[12:05] Response time degraded

ANSAI AI-Consolidated Alert:

🤖 INCIDENT CORRELATION

ROOT CAUSE: Single issue causing cascade
Database backup job started at 12:00, consuming resources

IMPACT:
✗ CPU spike (backup compression)
✗ Memory usage (backup buffer)  
✗ Disk I/O (backup writes)
✗ Network (backup to S3)
✗ App response time (resource contention)

ACTION: Normal behavior during scheduled backup
RECOMMENDATION: Move backup to off-peak hours (3 AM)

Alert count: 5 alerts → 1 insight

5. MySQL Replication with Intelligent Failover

Base Role: geerlingguy.mysql
Downloads: 5M+ | Stars: 600+

What it does: Installs MySQL/MariaDB with replication support.

ANSAI Enhancement: AI-detected replication lag with automatic failover.

# Deploy MySQL replication
- hosts: mysql_primary
  roles:
    - role: geerlingguy.mysql
      mysql_replication_role: 'master'

- hosts: mysql_replicas
  roles:
    - role: geerlingguy.mysql
      mysql_replication_role: 'slave'
      mysql_replication_master: "{{ groups['mysql_primary'][0] }}"

# Add ANSAI intelligent failover
- hosts: mysql_primary:mysql_replicas
  roles:
    - ansai.self_heal
    - ansai.replication_monitor
  vars:
    replication_monitoring:
      lag_threshold: 30  # seconds
      ai_analysis: true
      auto_failover: true

AI Failover Decision:

🤖 REPLICATION LAG DETECTED

PRIMARY: db-primary-01
REPLICA: db-replica-02
LAG: 450 seconds (critical)

AI ANALYSIS:
Replication lag due to long-running query on replica:
  Query: UPDATE users SET last_login WHERE...
  Duration: 7 minutes
  Blocking: 1,200 subsequent queries

TRADITIONAL APPROACH: Fail over immediately
  Risk: Replica is inconsistent, query mid-flight

AI RECOMMENDATION: Wait 45 seconds
  Reasoning: Query will complete in ~60s based on execution plan
  Safer: Let query finish, then verify consistency

Monitoring query progress... [=========>  ] 85%
Query completed. Replication caught up.
❌ Failover not needed. Crisis averted.

6. Security Hardening with AI Compliance

Base Role: geerlingguy.security
Downloads: 3M+ | Stars: 500+

What it does: Applies security hardening (firewall, SSH, fail2ban).

ANSAI Enhancement: AI-powered security audit and compliance reporting.

# Apply security hardening
- hosts: all
  roles:
    - role: geerlingguy.security
      security_ssh_port: 2222
      security_sudoers_passwordless: []

# Add ANSAI AI security audit
- hosts: all
  roles:
    - ansai.security_audit
  vars:
    security_frameworks:
      - CIS
      - NIST
      - PCI-DSS
    ai_remediation: true

AI Security Report:

🤖 AI SECURITY AUDIT RESULTS

COMPLIANCE: CIS Benchmark Level 1

✅ PASSED (45 checks)
⚠️  WARNINGS (3 checks)
❌ FAILED (2 checks)

CRITICAL FINDINGS:

1. [FAIL] Unencrypted passwords in /opt/app/config.ini
   Risk: High - Credentials exposed

   AI RECOMMENDATION:
   Move passwords to environment variables or Ansible Vault.

   Auto-fix available:
   $ ansai-vault-migrate /opt/app/config.ini

2. [FAIL] SSH accepts password authentication
   Risk: Medium - Brute force attacks possible

   AI RECOMMENDATION:
   Set 'PasswordAuthentication no' in /etc/ssh/sshd_config
   Ensure SSH keys are deployed first.

   Auto-fix: [Y/n]

3. [WARN] PostgreSQL listening on 0.0.0.0
   Risk: Low - Database exposed to network

   AI CONTEXT:
   Database is behind firewall (port 5432 blocked).
   Risk mitigated but not eliminated.

   Consider: Bind to 127.0.0.1 + SSH tunnel for admin access
