Multi-AZ student financial management platform leveraging Route 53, CloudFront, WAF, and Shield for global distribution and DDoS protection. Traffic flows through Cognito authentication to dual ALBs across AZ-1 and AZ-2, routing to EC2 API servers, ECS Fargate microservices, and Lambda functions for budget tracking, spend prediction, and notifications. Data layer spans RDS Aurora primary-standby, DynamoDB for sessions, ElastiCache Redis caching, and S3 for reports, with Step Functions orchestrating savings goals and SQS/SNS handling async events. This architecture demonstrates high-availability fintech patterns: multi-AZ redundancy, managed databases with failover, serverless compute for variable workloads, and comprehensive observability via CloudWatch, X-Ray, and CloudTrail. Fork this diagram to customize subnets, instance types, or add additional Lambda workflows for loan calculations or investment tracking. The management subnet integrates KMS encryption, Secrets Manager, IAM policies, SageMaker for predictive analytics, and Bedrock for AI-driven financial guidance.
