Multi-AZ job publishing flow leveraging WAF, CloudFront CDN, ALB, EC2 Job API, ECS Transform Service, and Lambda State Manager across us-east-1a and us-east-1b. User requests flow through WAF and CloudFront to ALB, which routes to EC2 instances that query MongoDB Primary, Elasticsearch indices, and trigger ECS transforms via API Gateway and SQS queues. State changes propagate through SNS to Lambda State Manager, updating DynamoDB Job State and Global Table replicas, then notify Career Site frontends via CloudWatch. This architecture demonstrates high-availability job state management with cross-AZ redundancy, asynchronous processing, and real-time visibility. Fork and customize this diagram on Diagrams.so to adapt subnets, instance types, or add additional integration endpoints. The design balances synchronous API responsiveness with asynchronous state propagation, critical for large-scale job publishing platforms.
