A comprehensive guide covering 30 essential system design concepts including client-server architecture, DNS, load balancing, database scaling techniques (sharding, replication, indexing), caching strategies, microservices, message queues, and distributed system principles like CAP theorem. The guide explains how these concepts work together to build scalable, fault-tolerant systems and includes practical examples of when to use each approach.

System Design was HARD until I Learned these 30 Concepts

You should get rid of those double dashes in your text - they always flag to me that it’s AI-written.
I don’t think it’s bad to generate docs like this (which are genuinely useful, thank you!) with AI, but it’s distracting as a user to notice giveaways like that.

As a backend developer, I wish I had found this sooner. This covers a good amount of system design and backend theory. Very helpful!

great article. thank you for sharing

really comprehensive article, system design is my absolute favorite part of engineering. some things that I would add to round this out:
<ul>
<li>buffer: having a mechanism to prevent downstream backpressure from data being moved too quickly can really help maintain stability (Redis Stream, et al)</li>
<li>observability: regardless of design, have logging, metrics, and tracing</li>
<li>data lake: storing large amounts of raw data for analytics or as a source of truth (BigQuery, et al.)</li>
</ul>
once you get all of your pieces together, think “where could this fail, how can I know about it, and how would I recover”, then test and even inject failures intentionally (chaos testing) to pressure test your system
