The sample inventory management microservice includes an EventBridge Schedule triggering a Lambda function to generate sample order data. An EventBridge rule persists the data in an SQS queue. A reserve-stock Lambda function starts a workflow, checking product availability in DynamoDB and creating purchase orders if needed. The create-purchase-order workflow sends purchase order emails and updates stock levels. The check-inventory-level workflow monitors stock levels via DynamoDB Streams, creating purchase orders for low inventory and updating product status as necessary. This microservice efficiently manages inventory, handles orders, and ensures products are in stock.
