About This Architecture

Multi-tier AWS network architecture integrating on-premises data centers via Direct Connect and VPN, with Route 53 DNS, CloudFront CDN, and WAF protecting inbound traffic through an Internet Gateway to an ALB. Application and data tiers span two availability zones across separate VPCs (DMZ, App, Data) with EC2 instances, RDS Multi-AZ databases, ElastiCache, and S3 storage isolated by security groups and network ACLs. Transit Gateway orchestrates connectivity between on-prem, DMZ, App, and Data VPCs while CloudWatch, CloudTrail, GuardDuty, and Security Hub provide unified observability and threat detection across the hybrid environment. Fork this diagram on Diagrams.so to customize CIDR blocks, add additional regions, or adjust security group rules for your organization's compliance requirements. This architecture demonstrates AWS Well-Architected Framework principles: security through defense-in-depth (WAF, Shield, GuardDuty), reliability via Multi-AZ RDS and cross-AZ EC2 placement, and operational excellence through centralized logging and identity management.

How do I design a secure AWS network that connects on-premises data centers with multi-tier application and data layers across availability zones?

This diagram shows a production AWS hybrid architecture using Direct Connect and VPN for on-prem connectivity, Transit Gateway for VPC orchestration, and a three-tier design (DMZ, App, Data VPCs) with Multi-AZ RDS, ALB load balancing, and centralized security via WAF, GuardDuty, and CloudTrail.
