Here is the link.
I've come across the book System Design Interview: an Insider's Guide by accident (paperback book, and online course). I was looking for good book resources after several people have been asking me how they can get better at building distributed systems or learning designing systems at scale. Especially when they don't have the opportunity to do so as part of their day-to-day work.
The topic is somewhat a chicken-and-egg one. You'll know how to design a large system after you designed one before. But if you've not done so: how would you build an URL shortener like bit.ly, with hundreds of millions of links? A chat app like Whatsapp? A file storage system like Dropbox or Google Drive?
There are many resources online - the most well-known one being System Design Primer on GitHub or reading High Scalability articles. In my case, I was looking for a more "structured" approach, as opposed to just dumping a bunch of concepts you need to know in these interviews.
This book is the most "real-world" systems design book I've come across that does a solid effort to teach concepts, step by step, to people who have yet to work at systems at scale. And it's also a welcome refresher to those who are familiar with some of these systems but would like to venture into various other types of large systems. It is clear from the start that the book was written by someone familiar with systems at scale. The author is Alex Xu, a software engineer previously at Oracle, Zynga, and Twitter.
The book comes with more than 10 case studies and a framework that it introduces and consistently uses with these case studies. There's also an accompanying online course that has the same content as the book, but you can follow along in a web browser, and the diagrams are colored.
