AI-Tenant 🚀

Multi-Tenant AI Microservices Platform built with Spring Boot

---

📌 Overview

AI-Tenant is a production-style multi-tenant microservices backend application designed using Spring Boot.
It demonstrates secure JWT-based authentication, API Gateway routing, tenant isolation, Redis caching, and CI/CD automation.

This project is intentionally built without:

• OAuth
• Refresh Tokens
• Eureka / Service Discovery

It focuses on clean architecture and real-world backend design.

🏗️ Architecture

Client → API Gateway → Auth Service / Business Services
↓
PostgreSQL
↓
Redis

Flow

1. User logs in via Auth Service.
2. Auth Service generates JWT containing tenantId.
3. Client sends JWT in Authorization header.
4. API Gateway validates JWT.
5. Gateway forwards request to appropriate service.
6. Service processes tenant-specific data.

🔐 Authentication Design

• Stateless authentication using JWT
• Token generated by Auth Service
• Token validated in API Gateway
• Tenant ID embedded inside JWT claims
• Redis used to cache user-tenant mapping
