## Cost Optimization Strategies

### 1. Infrastructure Consolidation

**Target**: 30-40% cost reduction

**Actions**:
- Shared Kubernetes clusters
- Shared database services
- Unified monitoring stack
- Consolidated storage

**Benefits**:
- Reduced infrastructure overhead
- Better resource utilization
- Lower operational costs

### 2. Resource Right-Sizing

**Strategy**: Match resources to actual needs

**Actions**:
- Monitor resource usage
- Adjust based on metrics
- Use auto-scaling
- Remove unused resources

**Tools**:
- Cloud cost management tools
- Resource monitoring
- Usage analytics

### 3. Reserved Instances

**Strategy**: Commit to long-term usage

**Actions**:
- Identify stable workloads
- Purchase reserved instances
- Use spot/preemptible for dev
- Optimize commitment terms

**Savings**: 30-70% on committed resources

### 4. Auto-Scaling

**Strategy**: Scale resources based on demand

**Benefits**:
- Pay only for what you use
- Handle traffic spikes
- Optimize for cost

**Implementation**:
```yaml
autoscaling:
  minReplicas: 2
  maxReplicas: 10
  targetCPUUtilizationPercentage: 70
```

## Cost Monitoring

### Key Metrics

Track:
- Infrastructure costs per project
- Resource utilization
- Cost per transaction/user
- Cost trends over time

### Cost Allocation

**By Project**:
- Tag resources by project
- Track costs per project
- Allocate shared costs

**By Environment**:
- Separate dev/staging/prod costs
- Optimize dev/staging
- Monitor production costs

## Optimization Areas

### Compute
- Right-size instances
- Use auto-scaling
- Spot instances for dev
- Container optimization

### Storage
- Lifecycle policies
- Compression
- Archive old data
- Optimize storage classes

### Network
- Optimize data transfer
- Use CDN
- Minimize cross-region traffic
- Compress data

### Database
- Right-size instances
- Use read replicas
- Optimize queries
- Archive old data
