“How do we design large-scale systems?”

Even those with IT experience can feel overwhelmed when suddenly trying to design a large-scale system.
Especially if you are in an interview situation, you will feel even more dizzy.
When designing a complex system, where and how should you start?

This book assumes an interview situation and explains how to build a large-scale system by starting with a simple system design and identifying issues and requirements that arise as the system expands.
Additionally, we introduce several design proposals tailored to the characteristics of each system, compare their pros and cons, and present the most suitable design proposal.
From single servers to complex systems, by engaging in virtual conversations with interviewers and practicing your imagery, you'll develop the muscle to design any system.
