DevOps & Site Reliability Engineering

De: Ajit Singh

Narrado por: Virtual Voice

This book is written from the ground up to serve as a comprehensive, implementation-driven guide to the worlds of DevOps & Site Reliability Engineering (SRE). It is designed to bridge the critical gap between academic computer science theory and the practical, in-demand skills required to build, deploy, and maintain modern, scalable software systems.


Philosophy: Competence Through Implementation

The guiding philosophy of this book is "competence through implementation." DevOps & Site Reliability Engineering are not spectator sports. They are hands-on disciplines where value is created by building, automating, and operating systems. This text is therefore designed as an apprenticeship in a book. It rejects the traditional model of a dense theoretical introduction followed by a few contrived examples. Instead, theory and practice are interwoven. Every core concept is immediately paired with a practical, step-by-step implementation. The reader is not just told what a CI/CD pipeline is; they are guided through the process of building one from scratch. They do not just read about Service Level Objectives; they learn how to define, measure, and act upon them for a live application. This approach ensures that knowledge is not merely memorised but is assimilated and converted into a tangible, demonstrable skill set.


Key Features

1. Curriculum-Aligned: Directly maps to core modules in DevOps, Cloud Computing, and Software Engineering for B.Tech/B.Eng and M.Tech/MSc degrees in the UK and worldwide.

2. Practicality First: Over 80% of the content is focused on hands-on tutorials, code examples, and practical implementation guides.

3. Beginner to Advanced: Starts with fundamental concepts and tools, progressively building to advanced topics like infrastructure as code, observability, and SRE strategy, making it suitable for a wide range of learners.

4. Modern Toolchain: Covers the most relevant and in-demand open-source tools in the industry: Git, Docker, Jenkins, Terraform, Ansible, Prometheus, and Grafana.

5. End-to-End Capstone Project: A complete final chapter dedicated to building a live project from the ground up, including all source code and detailed, step-by-step explanations.

6. Real-World Case Studies: Short case studies are interspersed to illustrate how large tech companies apply these principles to solve real-world reliability and scaling challenges.

7. Clear and Simple Explanations: Complex topics are demystified using clear language, analogies, and simple, annotated diagrams.


Key Takeaways

Upon completing this book, the reader will be able to:

1. Architect and Implement a full CI/CD pipeline to automate software builds, testing, and deployments.

2. Containerize applications using Docker for portability and consistency.

3. Define and Provision cloud infrastructure as code using Terraform.

4. Automate server configuration and software installation using Ansible.

5. Implement a robust monitoring and alerting system using Prometheus and Grafana.
