## 6. Estrategias de Deploy

### 6.1 Blue/Green (Backend API)

```
┌─────────────────────────────────────────────────────┐
│                 Load Balancer                        │
│             (100% blue / 0% green)                   │
└───────────┬─────────────────────────────────────────┘
            │
     ┌──────┴──────┐
     ▼             ▼
┌─────────┐   ┌─────────┐
│  BLUE   │   │  GREEN  │
│ Active  │   │  Idle   │
└─────────┘   └─────────┘

1. Deploy to GREEN (0% traffic)
2. Health check GREEN
3. Switch to GREEN (100% traffic)
4. Stop BLUE
```

**Ventajas:**
- Zero downtime
- Instant rollback
- Full testing pre-production

**Desventajas:**
- Requires 2x resources

---

### 6.2 Canary (ML Engine)

```
┌─────────────────────────────────────────────────────┐
│                 Load Balancer                        │
│              (90% stable / 10% canary)               │
└───────────┬─────────────────────────────────────────┘
            │
     ┌──────┴──────┐
     ▼             ▼
┌─────────┐   ┌─────────┐
│ STABLE  │   │ CANARY  │
│  v1.5   │   │  v1.6   │
└─────────┘   └─────────┘

1. Deploy canary (10% traffic)
2. Monitor metrics 5-10 min
3. If OK: Promote to 100%
4. If ERROR: Rollback
```

**Ventajas:**
- Early error detection
- Limited blast radius

**Desventajas:**
- Slower rollout
- Complex routing

---

### 6.3 Rolling Update (Data Service)

```
┌──────┐   ┌──────┐   ┌──────┐
│ v1.5 │   │ v1.5 │   │ v1.5 │
└──┬───┘   └──┬───┘   └──┬───┘
   │          │          │
   ▼          │          │
┌──────┐      │          │
│ v1.6 │      │          │  Step 1: Update instance 1
└──────┘      │          │
              ▼          │
           ┌──────┐      │
           │ v1.6 │      │  Step 2: Update instance 2
           └──────┘      │
                         ▼
                      ┌──────┐
                      │ v1.6 │  Step 3: Update instance 3
                      └──────┘
```

**Ventajas:**
- Simple
- Minimal extra resources

**Desventajas:**
- Brief downtime per instance
- Slower rollout

## 7. Monitoreo Post-Deploy

### 7.1 Health Checks

**Backend API:**
```bash
curl https://api.trading.com/health
# Expected:
{
  "status": "ok",
  "database": "connected",
  "redis": "connected",
  "uptime": 12345,
  "version": "1.5.2"
}
```

**ML Engine:**
```bash
curl http://ml-engine:8000/health
# Expected:
{
  "status": "ok",
  "gpu": true,
  "models_loaded": 5,
  "uptime": 67890
}
```

---

### 7.2 Metricas Clave

| Metrica | Threshold | Alerta |
|---------|-----------|--------|
| API p95 latency | <200ms | PagerDuty |
| API error rate | <1% | Slack |
| ML prediction time | <2s | Email |
| Database connections | <80% | Slack |
| Memory usage | <85% | Email |
| CPU usage | <75% | Email |

**Prometheus Queries:**

```promql
# API Error Rate
rate(http_requests_total{status=~"5.."}[5m]) /
rate(http_requests_total[5m]) > 0.01

# ML Prediction Latency
histogram_quantile(0.95, rate(ml_prediction_duration_bucket[5m])) > 2

# Database Connection Pool
pg_stat_activity_count / pg_settings_max_connections > 0.8
```

---

### 7.3 Alertas

**Slack Webhook:**
```groovy
slackSend(
    channel: '#deployments',
    color: 'good',
    message: """
        *Deploy Successful* :rocket:
        Service: ${env.IMAGE_NAME}
        Build: #${env.BUILD_NUMBER}
        Commit: ${env.GIT_COMMIT}
        Duration: ${currentBuild.durationString}
    """
)
```

**PagerDuty (Critical):**
```bash
curl -X POST https://events.pagerduty.com/v2/enqueue \
  -H 'Content-Type: application/json' \
  -d '{
    "routing_key": "...",
    "event_action": "trigger",
    "payload": {
      "summary": "Backend API down",
      "severity": "critical",
      "source": "jenkins"
    }
  }'
```

---

## 8. Rollback Procedures

### 8.1 Rollback Backend (Blue/Green)

```bash
# Desde Jenkins
docker-compose -f docker-compose.prod.yml -p backend-blue up -d
curl -X POST http://prod-lb.internal/switch -d '{"target": "blue"}'
```

**Duration:** <30 segundos

---

### 8.2 Rollback ML Engine

```bash
# Pull imagen anterior
docker pull registry.trading.com/ml-engine:${PREVIOUS_TAG}

# Recreate con imagen anterior
docker-compose -f docker-compose.prod.yml up -d --force-recreate ml-engine
```

**Duration:** ~2 minutos

---

### 8.3 Rollback Database

```bash
# Restaurar desde backup
aws s3 cp s3://trading-backups/db/backup_YYYYMMDD_HHMMSS.sql.gz .
gunzip backup.sql.gz
psql $DATABASE_URL < backup.sql
```

**Duration:** ~10-30 minutos (depende de tamano)

---

## 9. Secrets Management

### 9.1 Jenkins Credentials

```bash
# Crear credential
jenkins-cli create-credentials-by-xml system::system::jenkins \
    < credentials/stripe-secret-key.xml
```

**credentials/stripe-secret-key.xml:**
```xml
<com.cloudbees.plugins.credentials.impl.UsernamePasswordCredentialsImpl>
  <scope>GLOBAL</scope>
  <id>stripe-secret-key</id>
  <description>Stripe Secret Key</description>
  <username>stripe</username>
  <password>sk_live_...</password>
</com.cloudbees.plugins.credentials.impl.UsernamePasswordCredentialsImpl>
```

---

### 9.2 Rotation Schedule

| Secret | Rotation | Metodo |
|--------|----------|--------|
| JWT_SECRET | Quarterly | Manual |
| Database password | Monthly | Automated |
| API keys (external) | Yearly | Manual |
| SSL certificates | Automated | Let's Encrypt |
