The GREENEATS Food Ordering System is a serverless, scalable, and cost-efficient solution that streamlines food ordering. Customers can scan a QR code to access a web-based ordering platform, place orders, and receive real-time notifications. The system leverages AWS cloud services to ensure high availability, fault tolerance, and seamless order management. By integrating AWS Amplify, API Gateway, Lambda, SQS, SNS, and MongoDB, the system automates order processing and optimizes customer experience.
