Summary

This document outlines the architecture design of the FoodBasket platform. This should show a high-level logical overview and some simple user flows on how a request hits both ends.

Architecture Design

Includes the following components, truncated tenant2 for short:

• Home Platform: foodbasket.app. This provides the landing page to advertise the software, our visions and such things for a SaaS. Also includes simple SSO across the platform here to easily navigate to each tenant’s storefront, included as a way for consumers to order from.
• Tenant’s Platform: tenant.foodbasket.app. This is the hosted landing page of the restaurant registered with the service. This provides customization over brand identity like colors, fonts, and how to display the menus.
• Tenant’s POS System: pos.tenant.foodbasket.app. Provided as a separate system than the landing page to optimize for PWA-like architecture, as well as isolation between a work-user and a normal user.
• The Platform-wide Admin System: admin.foodbasket.app. Allows managing all tenants.

Other fluffs such as CDN, S3 service are out of scope for this document and will not be detailed.
