About This Architecture

Multi-AZ FinTech architecture on AWS with three-tier isolation: DMZ presentation layer using ALB and t3.medium EC2 instances across AZ-1 and AZ-2, application layer with t3.large servers behind internal ALB on private subnets, and isolated data layer featuring RDS Aurora with read replicas and ElastiCache Redis for caching. AWS Shield Advanced, WAF, and Network Firewalls protect against DDoS and unauthorized access, while security groups enforce least-privilege rules between tiers. Route 53 provides DNS failover, CloudFront accelerates content delivery, and CloudWatch plus CloudTrail enable comprehensive monitoring and compliance auditing. Fork this diagram to customize instance types, subnet ranges, or add additional AWS services like Secrets Manager and KMS for encryption key management. This architecture demonstrates enterprise-grade availability and security patterns critical for regulated financial services workloads.

How do I design a secure, multi-AZ FinTech infrastructure on AWS with proper network segmentation and DDoS protection?

This diagram shows a three-tier architecture spanning two availability zones: a public DMZ with ALB and web servers, a private application layer with internal ALB and app servers, and an isolated data layer with RDS Aurora and ElastiCache. AWS Shield Advanced, WAF, and Network Firewalls protect each tier, while security groups enforce least-privilege access between layers, ensuring compliance and
