## What it is
A free, open-source course and ebook teaching how to design large-scale systems and prepare for system design interviews. It covers networking fundamentals, databases, caching, distributed systems concepts, and worked interview examples like designing Twitter or Uber.

## Use cases
- prepare for a system design interview
- learn how to scale systems
- understand CAP theorem and sharding
- learn the difference between SQL and NoSQL databases
- study load balancing and caching strategies
- practice designing apps like WhatsApp or Netflix

## When to choose
- you are preparing for system design or senior engineering interviews
- you want a free, structured introduction to distributed systems concepts
- you prefer learning from a curated course with worked examples

## When to avoid
- you need hands-on code or runnable implementations of these patterns
- you want deep academic treatment of distributed systems theory
- you need vendor-specific cloud architecture guidance

## Facets
- artifact type: learning-resource
- maturity: active
- function: developer-tools, documentation
- domain: microservices, developer-tools, tutorials
- platform: cross-platform
- tags: system-design, interview-preparation, scalability, microservices, architecture, course, ebook, web-server
