Overview

Purpose

SupplyBoost bridges the gap between theoretical knowledge and practical implementation of distributed systems. While countless resources teach microservices, event-driven architecture, and cloud technologies in isolation, few demonstrate how these patterns work together in a cohesive, production-like system.

This project aims to:

• Provide a realistic, non-trivial example of microservices architecture
• Demonstrate modern software engineering practices and patterns
• Serve as a learning platform for developers transitioning to distributed systems
• Showcase the full lifecycle: design → development → deployment → operations

Target Audience

• Mid-level developers seeking hands-on experience with microservices
• DevOps engineers exploring containerization and orchestration
• Architecture enthusiasts studying system design patterns
• Students and educators looking for real-world examples beyond "todo apps"

What Makes This Different?

Unlike toy applications, SupplyBoost tackles real complexity:

• Multiple business domains: Identity, catalog, orders, inventory, payments, shipping, accounting
• Distributed transactions: Saga pattern for cross-service workflows
• Event-driven architecture: Asynchronous communication via Kafka
• Production-ready practices: Monitoring, logging, tracing, security, testing

Architecture

SupplyBoost follows a microservices architecture with event-driven patterns.

Quick Start

Note: The project is currently in the planning/restructuring phase. The following instructions will be functional after Week 1 of the roadmap.

# 1. Clone the repository
git clone https://github.com/deepkulk/SupplyBoost.git
cd SupplyBoost

# 2. Start infrastructure services (PostgreSQL, Kafka, Redis, etc.)
cd infrastructure/docker-compose
docker-compose up -d

# 3. Build all microservices
cd ../..
mvn clean install

# 4. Run services (once implemented)
# Individual services will have their own run instructions

# 5. Access the application
# Web UI: http://localhost:8080
# API Gateway: http://localhost:8080/api
# Grafana: http://localhost:3000
# Kibana: http://localhost:5601

First-time setup: See CONTRIBUTING.md for detailed development environment setup.

FAQ

Q: Is this production-ready?
A: Not yet. This is an educational project. While we follow production best practices, it's designed for learning, not commercial deployment.

Q: Can I use this for my startup/company?
A: Yes, under the Apache 2.0 license. However, you'll need significant additional work for true production readiness (security audit, scaling, compliance, etc.).

Q: Why not just use a monolith?
A: Monoliths are often the right choice! This project explicitly chooses microservices for educational value. See ADR-001 for the full reasoning.

Q: How can I contribute?
A: Check CONTRIBUTING.md and look for issues labeled good first issue or help wanted.

Q: What's the deployment strategy?
A: Local development uses Docker Compose. Production deployment targets Kubernetes (GKE/EKS/AKS). See docs/ARCHITECTURE.md.
