About This Architecture

Multi-AZ hospital management system on AWS with Route 53 DNS, CloudFront CDN, and WAF protecting patient, doctor, and admin access across two availability zones. Traffic flows through Internet Gateway and Application Load Balancers to EC2 instances running patient registration and appointments, Lambda billing functions, and ECS medical records containers, all backed by RDS Primary/Standby databases and ElastiCache session replication. RDS Primary replicates to RDS Standby across AZ-2, while medical documents are encrypted in S3 with KMS, and Secrets Manager secures credentials alongside CloudWatch monitoring and CloudTrail audit logging.

How do I architect a highly available hospital management system on AWS with multi-AZ failover and encrypted medical records?

This diagram shows a resilient healthcare architecture spanning two AWS availability zones with RDS Primary/Standby replication, Application Load Balancers in each AZ, and ElastiCache session replication for zero-downtime failover. Patient registration, appointments, billing, and medical records services are distributed across EC2, Lambda, and ECS, with all data encrypted via KMS and audit trails
