The System Design Interview, 2nd Edition

The System Design Interview, by Lewis C. Lin and Shivam P. Patel, is a comprehensive book that provides the necessary knowledge, concepts, and skills to pass your system design interview. It's written by industry professionals from Facebook & Google. Get their insider perspective on the proven, practical techniques for answering system design questions like Design YouTube or Design a TinyURL solution. Unlike others, this book teaches you exactly what you need to know. FEATURING THE PEDALS METHOD(tm), THE BEST FRAMEWORK FOR SYSTEM DESIGN QUESTIONS The book revolves around an effective six-step process called PEDALS: Process Requirements Estimate Design the Service Articulate the Data Model List the Architectural Components Scale PEDALS demystifies the confusing system design interview by breaking it down into manageable steps. It's almost like a recipe: each step adds to the next. PEDALS helps you make a clear progression that starts from zero and ends with a functional, scalable system. The book explains how you can use PEDALS as a blueprint for acing the system design interview. The book also includes detailed examples of how you can use PEDALS for the most popular system design questions, including: Design YouTube Design Twitter Design AutoSuggest Design a TinyURL solution ALSO COVERED IN THE BOOK What to expect and what interviewers look for in an ideal answer How to estimate server, storage, and bandwidth needs How to design data models and navigate discussions around SQL vs. NoSQL How to draw architecture diagrams How to build a basic cloud architecture How to scale a cloud architecture for millions of users Learn the best system strategies to reduce latency, improve efficiency, and maintain security Review of technical concepts including CAP Theorem, Hadoop, and Microservices HERE'S WHAT READERS ARE SAYING I just wanted to say that I got the Amazon Senior SDE job offer. I've failed the system design interview several times, and your material is the best resource out there. - Beto A., Senior SDE Just finished the dreaded Facebook Pirate interview. I used a modified version of PEDALS, and I had him grinning from ear to ear. - Jesse T., Software Engineer My recruiter just gave me the Google role, and I accept!!! I couldn't have made it through the technical round without PEDALS and your system design material. - Priya D., Product Manager
Understanding Distributed Systems, Second Edition

Learning to build distributed systems is hard, especially if they are large scale. It's not that there is a lack of information out there. You can find academic papers, engineering blogs, and even books on the subject. The problem is that the available information is spread out all over the place, and if you were to put it on a spectrum from theory to practice, you would find a lot of material at the two ends but not much in the middle. That is why I decided to write a book that brings together the core theoretical and practical concepts of distributed systems so that you don't have to spend hours connecting the dots. This book will guide you through the fundamentals of large-scale distributed systems, with just enough details and external references to dive deeper. This is the guide I wished existed when I first started out, based on my experience building large distributed systems that scale to millions of requests per second and billions of devices. If you are a developer working on the backend of web or mobile applications (or would like to be!), this book is for you. When building distributed applications, you need to be familiar with the network stack, data consistency models, scalability and reliability patterns, observability best practices, and much more. Although you can build applications without knowing much of that, you will end up spending hours debugging and re-architecting them, learning hard lessons that you could have acquired in a much faster and less painful way. However, if you have several years of experience designing and building highly available and fault-tolerant applications that scale to millions of users, this book might not be for you. As an expert, you are likely looking for depth rather than breadth, and this book focuses more on the latter since it would be impossible to cover the field otherwise. The second edition is a complete rewrite of the previous edition. Every page of the first edition has been reviewed and where appropriate reworked, with new topics covered for the first time.
