Architecture Best Practices
Multi-AZ Design Patterns
High Availability Web Applications:
- Application Load Balancer across all 5 AZs
- Auto Scaling Groups spanning multiple AZs
- RDS Multi-AZ deployment with cross-AZ replicas
- ElastiCache Redis cluster mode with multi-AZ failover
- S3 for static content with cross-region replication
Mission-Critical Databases:
- Aurora PostgreSQL Multi-AZ with 5 read replicas
- Automated backups to S3 with cross-region replication
- Point-in-time recovery to any second within 35 days
- Continuous backup to separate AWS account
- Regular disaster recovery testing and validation
Disaster Recovery Architecture:
- Primary workload spanning 3 AZs in Sydney
- Warm standby in Melbourne Availability Zone
- Automated failover with Route 53 health checks
- RPO: 5 minutes, RTO: 15 minutes
- Quarterly DR testing and documentation
Cost Optimization Strategies
Right-Sizing and Reserved Instances
• Analyze CloudWatch metrics to identify oversized instances
• Purchase 1-year Convertible Reserved Instances for steady workloads
• Use Savings Plans for flexible commitment-based discounts
• Average savings: 40-60% vs. on-demand pricing
Spot Instances for Non-Critical Workloads
• Development and testing environments
• Batch processing and data analysis
• CI/CD pipeline workers
• Average savings: 70-90% vs. on-demand pricing
S3 Intelligent-Tiering
• Automatic movement between access tiers
• No retrieval fees or minimum storage duration
• Ideal for unpredictable access patterns
• Average savings: 30-40% on storage costs
Auto Scaling Optimization
• Scale based on actual demand, not peak capacity
• Use target tracking scaling policies
• Implement scheduled scaling for predictable patterns
• Average savings: 25-45% on compute costs
Security Enhancements
Network Security
• AWS Shield Standard protection against DDoS attacks
• AWS WAF protecting web applications
• VPC Flow Logs for network traffic analysis
• Security Groups and Network ACLs for defense in depth
Data Protection
• Encryption at rest using AWS KMS with Australian keys
• Encryption in transit with TLS 1.3
• S3 Object Lock for immutable backups
• AWS Backup for centralized backup management
Identity and Access Management
• Multi-factor authentication for all IAM users
• Least privilege access policies
• AWS Organizations for multi-account governance
• AWS IAM Identity Center for SSO
Compliance and Governance
• AWS Config for resource configuration tracking

• Amazon GuardDuty for threat detection
Migration Strategies
Rehost (Lift and Shift)
• Fastest migration approach: 2-4 weeks typical
• Minimal application changes required
• Immediate benefit from AWS reliability
• Foundation for future optimization
Replatform (Lift, Tinker, and Shift)
• Moderate optimization during migration: 4-8 weeks
• Leverage managed services (RDS, ElastiCache)
• Improved performance and reduced operational overhead
• Better cost efficiency than pure rehost
Refactor (Re-architect)
• Maximum cloud-native benefits: 12-24 weeks
• Microservices and serverless architectures
• Highest performance and scalability
• Long-term lowest total cost of ownership
Retain or Retire
• Keep on-premises if migration not justified
• Decommission unused or redundant applications
• Focus resources on high-value migrations
