Ramchandani H.K. Hands-On System Design: Learn System Design, Scaling Applications, Software Development Design Patterns with Real Use-Cases

BPB Publications, 2022. — 228 p.The ultimate guide to ace your system designing interviews.Key Features:Provides step-by-step solutions to real-world problems related to system design and development.
Includes detailed explanations of each OOP idea and design pattern, along with code snippets in the C++ style.
Contains illustrations and demonstrations that describe the technologies enabling modern scalable systems.Description:Scaling software applications is the focus of this book, which takes the reader on an in-depth journey. You'll have a better understanding of how to create a scalable, enterprise-level application after reading this guide.The book discusses system design principles, computer networks, major networking protocols, strategies for scaling data access, and various architectural styles for creating the system. A thorough examination of various technologies such as Cache Memory, CDN, Load Balancers, and Messaging Queues are conducted and their implementation. The book also demonstrates how you can use these combinations of technologies in the best way to build a scalable enterprise-level system. The examination of several architectural styles for system design assists you in choosing the best path for architecting your system. Additionally, the book explores object-oriented programming concepts and design patterns that facilitate the creation of clean, maintainable code. The reader will develop an intuitive knowledge of numerous tools and approaches for creating a scalable system by using several actual system design examples.This book can tackle any system design problem you may meet in your current position or interviews. You'll learn how to design a system from scratch, and the examples in the book will help you to improve your skills.The book is primarily divided into three parts. The first part of the book contains five chapters that explain the fundamentals of system design. It discusses various technologies like Cache memory, Messaging queues, Databases, etc. which are used to build modern-day scalable distributed systems. It also touches on some core networking concepts like the OSI model, and important protocols like HTTP and REST architecture. Furthermore, different strategies to scale databases horizontally and vertically are also covered. In addition, an emphasis on different architectural styles – monolithic, service-oriented, and microservices is put to help a user understand the pros and cons of each one. Also, Object-oriented principles are discussed and explained with C++-style code snippets.The second part of the book takes the responsibility of explaining – how to start the system design practically. It contains three chapters and the first chapter explains the various design patterns used in the industry with C++-style code snippets. It explains different behavioral, creational, and structural design patterns. The next chapter describes the basic tools and techniques to design a system in an object-oriented way. It describes how to define system requirements and how to use tools like class diagrams to depict important objects of the system. Finally, the tools and techniques discussed are used to design a system so that readers can understand how to put into use everything they just learned.The final part of the book contains five chapters and each chapter contains a dedicated system design problem. In each chapter, a feasible solution to the system design problem is discussed using the techniques and technologies learned in the previous two sections.What you will learn:Acquaint yourself with the fundamentals of computer networks and major networking protocols.
