About This Architecture
Multi-AZ veterinary management system on AWS with CloudFront CDN, WAF, and Application Load Balancer routing traffic across two availability zones. ECS microservices for appointment scheduling, consultations, and treatment management connect to RDS Primary/Standby databases, DynamoDB replicas for medical history, and ElastiCache for session management. Lambda functions trigger SNS alerts, Cognito handles authentication, and S3 stores clinical files, while CloudWatch monitors the entire infrastructure for high availability and disaster recovery.
