About This Architecture

Multi-tier FinTech web application spanning two AWS availability zones with layered security controls including Route 53 DNS, CloudFront CDN, AWS Shield, and WAF at internet, application, and database tiers. Traffic flows from internet clients through Route 53 to CloudFront, then AWS Shield and WAF before reaching dual ALBs distributing to auto-scaled t3.medium web servers in public subnets. Web servers forward requests through application-tier WAF to auto-scaled c5.large app servers in private subnets, which access RDS Primary and Standby databases plus ElastiCache via database-tier WAF in isolated private subnets. Secrets Manager, KMS, CloudWatch, CloudTrail, and GuardDuty provide encryption, audit logging, and threat detection across the architecture. Fork this diagram to customize subnets, instance types, or add additional security controls like VPC Flow Logs or AWS Config for your FinTech compliance requirements.

How do I design a secure, scalable FinTech application architecture on AWS with multiple availability zones and layered security controls?

This diagram shows a production-grade FinTech architecture using Route 53 for DNS, CloudFront and AWS Shield for DDoS protection, WAF at internet/app/database tiers, auto-scaled web and app servers across two AZs, RDS with standby failover, ElastiCache for caching, and Secrets Manager, KMS, CloudTrail, and GuardDuty for security and compliance.
