1. Distributed Systems (A Real-World Ride-Sharing Platform Journey)

File: distibutedSystem/distributed-systems.html

Overview: A comprehensive introduction to distributed systems concepts using a real-world ride-sharing platform 🚗 (like Uber) as a case study. This presentation walks through the fundamental challenges of building scalable, reliable systems across multiple cities.

Topics Covered:

• Definitions & Characteristics

  • What is a Distributed System?
  • When and why to use Distributed Systems
  • Real-world examples (Uber, Google Maps, Netflix, WhatsApp, Instagram, Banking Apps)
  • Challenges and trade-offs in distributed systems

• Basic Concepts

  • Nodes and State (Compute + State)
  • State Machine Replication (SMR)
  • Distributed Logs and event sourcing
  • Quorums and Majority voting
  • Data replication strategies

• Consensus Algorithms

  • Introduction to Raft Consensus Algorithm
  • Leader Election
  • Log Replication
  • Key concepts: Terms, Elections, Majority consensus
  • Fault Tolerance and Byzantine failures

• Real-World Application

  • Journey from single server to distributed architecture
  • Handling scale (1000s of simultaneous rides)
  • Consistency models (Strong vs Eventual Consistency)
  • Fault tolerance in practice

Key Learning:

• How distributed systems solve real-world scalability problems
• Why consensus algorithms are critical for data consistency
• Trade-offs between consistency, availability, and partition tolerance
• Practical implementation patterns used by major tech companies

Duration: ~45-60 minutes
