Fundamentals

Start here if you are building the foundation for system design interviews. These pages explain the core ideas that show up in nearly every design.

  1. System Design Basics
  2. Scalability
  3. Load Balancing
  4. Consistency Models
  5. Replication & Redundancy
  6. Client-Server Communication
  7. High Level Design vs Low Level Design

What to Focus On

  • Learn the vocabulary first so later pages are easier to follow.
  • Understand why scaling, consistency, and communication recur in every design.
  • Use these pages as your theory layer before moving to components and case studies.

Next Step

Once you understand the basics, move to Components.
