About This Architecture

Multi-AZ blood donation platform on AWS with CloudFront CDN, AWS WAF, and Route 53 routing traffic across two availability zones for high availability. Application tier spans EC2, ECS microservices (Donor, Admin, Recipient), and Lambda functions (Search, Request handlers) in private subnets behind ALBs. Data layer uses RDS Primary/Standby replicas, DynamoDB Global Tables, and ElastiCache for sessions, ensuring zero-downtime failover and disaster recovery. This architecture demonstrates AWS best practices for healthcare compliance, multi-region resilience, and cost-optimized compute scaling. Fork and customize this diagram on Diagrams.so to adapt subnet ranges, instance types, or add additional services like S3 for document storage or Kinesis for real-time analytics.

How do you design a highly available blood donation platform on AWS across multiple availability zones?

This diagram shows a production AWS multi-AZ architecture using Route 53 for DNS failover, CloudFront CDN with AWS WAF for security, and dual ALBs across us-east-1a and us-east-1b. The application tier runs ECS microservices and Lambda functions in private subnets, while the data tier uses RDS Primary/Standby replicas, DynamoDB Global Tables, and ElastiCache for zero-downtime failover and complian
