Key Features

• Highly available architecture across multiple Availability Zones
• Auto-scaling capabilities for handling varying loads
• Secure network design with public and private subnets
• Managed database service with Amazon RDS
• Comprehensive monitoring with CloudWatch
• Load balancing for optimal traffic distribution

Security Considerations

• Private subnets for application and database layers
• NAT Gateway for secure outbound internet access
• Security groups for fine-grained access control
• Network ACLs for additional security layer

Best Practices Implemented

2. Auto-scaling for handling variable workloads
3. Proper network segmentation
4. Secure database configuration
5. Regular monitoring and alerting
6. Backup and disaster recovery setup

Infrastructure Management

• Infrastructure as Code (IaC) principles followed
• Regular backups and snapshots configured
• Monitoring and alerting in place
• Auto-scaling policies based on demand
