About This Architecture

Event-driven order processing pipeline using AWS SQS, payment gateway integration, and DynamoDB invoice storage with centralized CloudWatch logging. The sequence spans five phases: order ingestion to SQS, message consumption by payment and notification services, payment processing with invoice management, notification dispatch, and unified observability via CloudWatch Logs. This architecture decouples order intake from payment processing, enabling horizontal scaling and fault isolation across services. Fork and customize this diagram on Diagrams.so to adapt payment workflows, add retry logic, or integrate additional AWS services like Lambda or SNS. Note the critical warning: payment-workflow lacks SQS DeleteMessage implementation, creating duplicate processing risk—essential to address before production deployment.

People also ask

How do I design an asynchronous order processing workflow in AWS using SQS and payment gateway integration?

This diagram shows a five-phase sequence: orders enter via SQS, payment and notification services consume messages in parallel, payment processing updates DynamoDB invoices, notifications dispatch, and all services log to CloudWatch. Critical: implement SQS DeleteMessage in payment-workflow to prevent duplicate order processing.
