theByteBook

This repository is the source for a published Chinese-language technical book titled "Deep Dive into High-Availability System Principles and Design." The book is available for purchase on JD.com and covers the core ideas behind building large-scale internet infrastructure that stays up, runs efficiently, and keeps costs manageable.

The content is organized around three main themes: networking, cluster and service governance, and FinOps (which is about understanding and controlling the cost of running cloud infrastructure). Within those themes the book covers technologies like containers (packaged software environments), Kubernetes (a system for running many containers at once), Service Mesh (a layer that manages communication between software services), Serverless computing, and high-performance networking approaches.

The author wrote this by working through each topic carefully, the way a student would explain something to make sure they truly understand it. The stated goal was both to deepen the author's own knowledge and to produce something useful for other engineers and learners working in cloud infrastructure.

The book can be read online at thebyte.com.cn. If you want a local copy, the site is built with VuePress 2, a tool that turns text files into a browsable website.
