دانلود کتاب طراحی عملی سیستم

The idea of writing this book originated in my mind when I was reading a tech blog that discussed building a social media website. I was not able to absorb all the content at once as there were many grey areas in my system designing mindset. Post that I appeared in some system designing discussions and I couldn’t design a satisfactory scalable system. As curious as I was to learn something new, I got inquisitive and started reading various blogs and books to increase my knowledge. Slowly, reading tech blogs became a habit and I found it convenient to document this knowledge in a book. The book is meant to serve programmers – beginners or mid-senior level and students who are willing to learn the key aspect of scalable system designing. I have learned that this knowledge will be helpful to you, first, professionally, and second, in your system design interviews. The book is primarily divided into three parts. The first part of the book contains five chapters that explain the fundamentals of system designing. 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, 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.
