System Design (System Design)
Learn how to design systems at scale and prepare for system design interviews
About the Book
System design interviews can be quite open-ended and intimidating as it is a very extensive topic. There can be multiple solutions to even the most basic system design problems. My objective with this book is to help you learn the fundamentals and explore the advanced topics of system design. This will also provide you with a reliable strategy to prepare for system design interviews.
