Multi-AZ microfrontend portal architecture leveraging AWS Route 53, CloudFront CDN, WAF, and Shield for global distribution and DDoS protection. MFE Shell App runs on ECS Fargate across two availability zones with dedicated ALBs, while 11 specialized microfrontends (Login, Dashboard, Policy Tracker, Commission Data, Quote Mgmt, RMD Policies, and others) are independently deployed and versioned in ECR. Backend services scale via Lambda-based BFFs (Policy, User, Commission, Document, Notification) orchestrated by Step Functions, with RDS Aurora Multi-AZ primary-standby, DynamoDB Global Tables, ElastiCache Redis replication, and async messaging through SQS and SNS. Cognito handles authentication, Secrets Manager and KMS secure credentials, and CloudWatch, X-Ray, CloudTrail provide observability across both AZ-1 and AZ-2. Fork this diagram to customize for your PAS integrations (LifePro, FAST, Life 70), billing systems, and document management backends.
