Take a quick refresher on the essentials of distributed systems, including core concepts and theorems.

Deep Dive into System Design Interview

This module talks about establishing the basic principles of distributed systems. It explains the scope of their functionality by discussing what distributed systems can and can’t achieve. It also covers the basic algorithms and protocols of distributed systems through easy-to-follow examples and diagrams, which illustrate the thinking behind design decisions and expand on how they can be practiced.

Distributed Systems

Models can be organized in a hierarchical tree according to their strictness and the guarantees they provide. 

# Hierarchy tree
The following illustration depicts such a tree that contains some of the models.


Let's look at the hierarchy of the consistency models and isolation levels based on the strictness and guarantees they provide.
