Multi-AZ recruitment agency management system on AWS with Route 53 DNS, CloudFront CDN, WAF, and Shield protecting a VPC spanning two availability zones. Traffic routes through Application Load Balancers to EC2 web portals and containerized ECS microservices (API, Interview Scheduler, Payment Tracker, Deployment Manager) alongside Lambda functions for document verification, visa processing, and notifications orchestrated by Step Functions. Data layer includes RDS Aurora with read replicas, ElastiCache Redis for sessions, DynamoDB Global Tables for tracking, and S3 buckets for documents and backups, with SQS, SNS, EventBridge, CloudWatch, and CloudTrail providing asynchronous messaging, monitoring, and audit trails. This architecture demonstrates high-availability, multi-tenant SaaS best practices with role-based access control via Cognito, automated recruitment workflows, and disaster recovery across regions.
