System Design Study with Multi-Language Implementations

Welcome to the System Design Study project, where we explore and implement various system design concepts using multiple programming languages: PHP, Go, JavaScript, and Java. This repository provides practical examples, theoretical explanations, and system diagrams for a comprehensive understanding of real-world system design cases.

Introduction

System design is an essential aspect of software engineering, involving the creation of scalable, reliable, and maintainable systems. This project delves into various design cases, offering theoretical insights alongside practical implementations in multiple languages.

Each system design case includes:

• Detailed Theorem Explanation
• Diagrams and Architecture
• Real-World Examples
• Code Implementations
• Tests for Verification

System Design Cases

1. Authentication System

   • Theory: Token-based auth, OAuth, JWT
   • Diagram: Authentication Diagram
   • Example: Secured login and session management

2. Caching System

   • Theory: Cache types (LRU, LFU), Redis
   • Diagram: Caching Diagram
   • Example: Distributed cache for high-traffic apps

3. Load Balancing

   • Theory: Round-robin, least connections
   • Diagram: Load Balancing Diagram
   • Example: Distributing requests across microservices

... More cases coming soon!
