Architectural Drawing
This architecture showcases a scalable and secure e-commerce platform designed for custom merchandise businesses. Users can access the system through either mobile devices (Android and iOS) or web browsers on desktop and laptop computers. All incoming traffic is efficiently managed and distributed by a load balancer, ensuring high performance and reliability for every request.
The front end consists of two specialized applications: a React-based web app for desktop users and a React Native mobile app for mobile shoppers. Both apps interface directly with a centralized Node.js API server hosted in the AWS cloud. This backend layer is responsible for processing business logic, authenticating users, and managing order workflows.
Data management is facilitated by AWS DynamoDB and S3, providing fast, scalable access to user profiles, product information, and media assets. For payment processing, the Node.js API seamlessly integrates with third-party gateways including Stripe and PayPal, ensuring secure and versatile transaction options for customers. Automated deployment and continuous integration are achieved via a CI/CD pipeline, supporting rapid updates and stable releases, while 24/7 monitoring and support maintain platform uptime and swiftly resolve any operational issues.
Overall, this modular, cloud-based architecture delivers reliability, scalability, and security, empowering custom merchandise startups to efficiently launch and grow their e-commerce business.
