About This Architecture

Multi-AZ freelance marketplace on AWS with redundant application and data tiers across us-east-1a and us-east-1b. Client and Freelancer traffic flows through CloudFront CDN and WAF-protected ALBs to Account Management, Job Management, Job Flow, Project Tracking, and Payment Service microservices in private app subnets. RDS Primary (db.r5.large) in AZ-1 replicates to RDS Standby in AZ-2, while DynamoDB and ElastiCache replicate across zones for high availability. Payment Gateway integrates with the Payment Service layer, and CloudWatch monitors the entire stack. Fork this diagram to customize subnet ranges, add Auto Scaling Groups, or extend with Lambda-based job processors.
