## What it is
A free course outline by Kyle Kingsbury (Jepsen) for a 16-32 hour introduction to distributed systems fundamentals. It covers core concepts like time, ordering, faults, safety, and liveness, plus algorithm classes and production concerns.

## Use cases
- learn distributed systems fundamentals
- prepare for designing distributed systems
- find a shared vocabulary for consistency and fault tolerance
- study distributed systems algorithms before reading papers
- train backend engineers on distributed systems concepts

## When to choose
- you want a practitioner-oriented overview of distributed systems theory and practice
- you need a structured curriculum to self-study distributed systems
- you want free, expert-authored lecture materials from the Jepsen author

## When to avoid
- you need hands-on labs only - pair it with the Maelstrom labs
- you want a textbook with full proofs rather than an outline
- you need a software tool or library rather than educational material

## Facets
- artifact type: learning-resource
- maturity: stable
- function: documentation, developer-tools
- domain: microservices, tutorials, developer-tools
- platform: cross-platform
- tags: distributed-systems, lecture-notes, jepsen, training-materials, education
