Challenge Overview

Following the modernization of Al Safadi’s compute infrastructure using AWS Graviton-based EC2, the next strategic objective was to digitalize and expose restaurant services such as menu browsing and online ordering. Al Safadi wanted a lightweight, highly scalable, and secure API-driven architecture that could be consumed by both in-store POS systems and mobile applications

Legacy systems were difficult to scale and costly to maintain. API responsiveness and security were also major concerns due to increasing online traffic and attempted attacks. Al Safadi partnered with F9 Infotech to design a serverless API backend on AWS that addressed performance, observability, and security—while maintaining cost efficiency.

Solution Overview

F9 Infotech delivered a highly secure and scalable serverless API solution to Al Safadi, empowering their digital transformation journey in the restaurant industry. By leveraging AWS managed services, our team ensured that the application was resilient, cost-efficient, and easy to maintain.
We worked collaboratively with the client to understand real-time ordering workflows, traffic behavior during peak hours, and internal operations. Based on these insights, we recommended Amazon Web Services as the ideal platform due to its ability to deliver seamless scaling, integrated security controls, and ease of management.
F9 Infotech implemented a robust API backend using Amazon API Gateway integrated with AWS Lambda and Amazon DynamoDB. The APIs handled online menu display and real-time order submissions from mobile apps and POS systems. Sensitive APIs (e.g., order dashboards) were exposed via private VPC links for secure internal access.
Security was a top priority, AWS WAF was deployed to protect public endpoints, Lambda authorizers were planned for fine-grained access control, and API Gateway’s request validation blocked malformed traffic at the edge. CloudWatch and X-Ray enabled full observability across all transactions. IAM roles were tightly scoped using least privilege principles.
This fully serverless architecture eliminated infrastructure management overhead while offering agility, performance, and reduced cost. The solution gave Al Safadi real-time visibility, enhanced customer experience, and robust protection against web-based threats.
