10 resources to become a system design hero


System Design serves as the blueprint for creating a software system. It involves defining the architecture, components, and interfaces necessary to meet specific requirements. This topic is highly relevant in the software development industry and is frequently discussed in technical interviews. Acquiring system design skills can indeed lead to a 10x salary increase. 🚀
Certainly! System design is indeed a very complex subject that goes beyond mastering a coding language . It includes understanding system architectures, design patterns, performance optimization, and other intricate topics. Learning system design from specialists or coding bootcamps can be expensive, often costing around $1000.
To help you on your journey to becoming a system design hero, in this article I have curated a list of free and valuable resources .

1. System Design Roadmap

Contains visually designed and easy to udestand roadmaps attached with useful links to master system design and other programming resources for free

8. machine-learning-systems-design

A book on machine learning system design

GitHub logo chiphuyen / machine-learning-systems-design

A booklet on machine learning systems design with exercises. NOT the repo for the book "Designing Machine Learning Systems"

Machine Learning Systems Design

Read this booklet here.

This booklet was my initial attempt to write about machine learning systems design back in 2019. My understanding of the topic has gone through significant iterations since then. My book Designing Machine Learning Systems (O'Reilly, June 2022) is much more comprehensive and up-to-date. The new book's repo contains the full table of contents, chapter summaries, and random thoughts on MLOps tooling.

This booklet covers four main steps of designing a machine learning system:

  1. Project setup
  2. Data pipeline
  3. Modeling: selecting, training, and debugging
  4. Serving: testing, deploying, and maintaining

It comes with links to practical resources that explain each aspect in more details. It also suggests case studies written by machine learning engineers at major tech companies who have deployed machine learning systems to solve real-world problems.

At the end, the booklet contains 27 open-ended machine learning systems design questions that might come…
