About This Architecture
Multi-AZ healthcare platform leveraging AWS CloudFront CDN, Route 53 DNS, WAF, and ALB for global distribution and DDoS protection across two availability zones. API Gateway and AppSync GraphQL route requests to microservices (User, Health, Consultation, Notification, Matching, Knowledge Services) deployed on ECS Fargate, EKS Kubernetes, Lambda, and Elastic Beanstalk in private subnets. AI Layer integrates SageMaker, Bedrock, and Comprehend for predictions, recommendations, and NLP across both AZs, while Data Layer uses RDS Primary/Standby, DynamoDB, ElastiCache Redis, and DocumentDB for persistence and caching. Integration tier connects external APIs (Weather, Healthcare, Insurance) via SQS, SNS, EventBridge, and Step Functions; Glue ETL and Kinesis Streams enable real-time data pipelines. This architecture demonstrates high availability, fault tolerance, and HIPAA-aligned security with Cognito Auth, Certificate Manager, Secrets Manager, and comprehensive observability via CloudWatch, X-Ray, and CloudTrail.
