🔧 DevOps Best Practices

1. Security Hardening

• Regular security updates and patches
• Secrets management with AWS Secrets Manager
• Network segmentation with VPC and Security Groups
• SSL/TLS encryption for all communications
• Regular security audits and penetration testing

2. Backup & Disaster Recovery

• Automated database backups with point-in-time recovery
• Cross-region backup replication
• Infrastructure as Code for quick recovery
• Regular disaster recovery testing

3. Performance Optimization

• Auto-scaling based on CPU and memory metrics
• Content delivery through CloudFront CDN
• Database query optimization and indexing
• Redis caching for frequently accessed data
• Image optimization and compression

4. Cost Optimization

• Reserved instances for predictable workloads
• Spot instances for non-critical tasks
• S3 lifecycle policies for old data
• Regular cost analysis and optimization reviews

5. Compliance & Governance

• AWS Config for compliance monitoring
• CloudTrail for audit logging
• Regular compliance assessments
• Data retention and privacy policies
