Abstract

Devops Book is an open-source Blockchain & Cloud Computing project. Code samples for the book and blog post series "Fundamentals of DevOps and Software Delivery" by Yevgeniy Brikman. The code samples are organized by chapter (e.g., ch1, ch2, etc.), and within each chapter, by tool (e.g., ansible, kubernetes, tofu). For example, the example Packer template in Chapter 2 will be in the folder ch2/packer, and the example OpenTofu module called lambda in Chapter 3 will be in the folder ch3/tofu/modules/lambda. It is built using HCL, AWS, Docker, Kubernetes. The complete source code is publicly available on GitHub under the MIT License, making it a useful reference for students building a Blockchain & Cloud Computing mini project or final-year project.

1. Introduction

The code samples are organized by chapter (e.g., ch1, ch2, etc.), and within each chapter, by tool (e.g., ansible, kubernetes, tofu). For example, the example Packer template in Chapter 2 will be in the folder ch2/packer, and the example OpenTofu module called lambda in Chapter 3 will be in the folder ch3/tofu/modules/lambda.

It's worth noting that most of the examples show you what the code looks like at the _end_ of a chapter. If you want to maximize your learning, you're better off writing the code yourself, from scratch, and checking the "official" solutions only at the very end.

2. Objective

Code samples for the book and blog post series "Fundamentals of DevOps and Software Delivery" by Yevgeniy Brikman

This project demonstrates how HCL, AWS, Docker can be applied to a real-world Blockchain & Cloud Computing problem.

4. Technology Stack

HCLAWSDockerKubernetes

5. System Requirements

General requirements for this technology stack — check the README for exact versions.

  • Terraform CLI
  • Cloud provider account (e.g. AWS) with CLI configured
  • Git (to clone the repository)

6. Installation & Setup

git clone https://github.com/brikis98/devops-book.git
cd devops-book

Full setup instructions are in the project README.

7. Future Enhancements

Suggested extensions you can add to make this your own project.

  • Add a CI/CD pipeline with GitHub Actions
  • Deploy to a public test network or cloud free tier
  • Add monitoring and cost alerts

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

  1. Why does this problem need a blockchain or cloud-native design?
  2. Explain the smart contract / infrastructure components and how they interact.
  3. How are gas costs or cloud costs kept under control?
  4. How is the system secured (keys, IAM, access control)?
  5. How would the solution scale to many more users?
