3. Network Security

   • VPC configuration
   • Security groups
   • WAF implementation
   • DDoS protection

Performance Optimization

Strategies

1. Caching
2. Load balancing
3. Auto-scaling
4. Content delivery networks

Monitoring and Logging

• Metrics collection
• Log aggregation
• Alert configuration
• Performance analytics

Cost Management

1. Resource Optimization

   • Right-sizing instances
   • Reserved capacity
   • Spot instances
   • Auto-scaling policies

2. Cost Monitoring
