1 Business Requirements Analysis

Before diving into technical specifications, conduct a SWOT analysis of your operational needs. Key considerations include:

• User Traffic Patterns: Analyze historical metrics showing peak loads (e.g., 30,000 concurrent users during Black Friday)
• Compliance Requirements: GDPR (EU), HIPAA (healthcare), or PCI DSS (payment processing) regulations
• Disaster Recovery Objectives: RTO (Recovery Time Objective) < 15 minutes and RPO (Recovery Point Objective) < 5 minutes
• Scalability Requirements: Predicted 200% growth in customer base within 12 months

• Scale-In: Reduce to 4 vCPUs if <40% utilization for 15 minutes
• Scale-Out: Add 2 vCPUs when >85% utilization for 10 consecutive minutes

2 Security Hardening

Perform regular audits using:

1. Initial Setup:

   • Disable root login (use SSH keys)
   • Update package lists and apply security patches (CVE-2023-1234)
   • Configure fail2ban for brute force protection

2. Weekly Checks:

   • Run vulnerability scans (Nessus or OpenVAS)
   • Verify SSL certificate expiration (Let's Encrypt with 90-day rotation)
   • Test firewall rules (iptables or AWS Security Groups)

3. Monthly Audits:

   • Check SSH key permissions (0400 for private keys)
   • Review process list (no unnecessary services running)
   • Test failover procedures (simulated data center outage)

3 Backup Strategy

Implement multi-layered backup:

• Layer 1 (Application Data):

  • Incremental backups every 2 hours (AWS Backup with 14-day retention)
  • Version control (Git for code repositories)

• Layer 2 (System State):

  • System image snapshots (AWS EC2 Instance Store volumes)
  • Windows Server System State backups (Veeam Agent)

• Layer 3 (Disaster Recovery):

  • Cross-region replication (AWS Cross-Region Replication)
  • Test failover in under 4 hours (using AWS Backup DR testing)

Chapter 4: Deployment and Operations

1 Continuous Integration/Continuous Deployment (CI/CD)

Implement automated pipelines using:

• GitLab CI/CD:

  • Pipeline stages: Code scan → Docker build → Security test → Load test → Deploy to staging
  • Variables management (AWS Secrets Manager integration)
  • Rollback mechanism (自动检测 failed deployments)
