DevOps Unleashed with Git and GitHub

DevOps and Developer Experience – Entering the World of Modern Development

In this chapter, we will cover two main topics. First, we will address what DevOps is, the main subject of this book. Next, we will delve into developer experience, a strategy essential for maintaining and continually achieving success in DevOps within an organization. Within this context, we will also introduce the tools, Git and GitHub.

This chapter serves as a compass for those about to embark on learning about DevOps, tools, and collaboration practices for DevOps. It will establish foundational knowledge on the positioning of these concepts and practices and how they can enhance your development process.

We will cover the following main topics in this chapter:

  • DevOps – Accelerating the development cycle by reducing friction
  • Developer experience – A strategy for developer excellence
  • Git – Where code collaborations begin
  • GitHub – The AI-powered developer...

DevOps – Accelerating the development cycle by reducing friction

Let’s get started by learning the DevOps fundamentals.

The world of technology has various terms. At times, such terms can be abstract, and people tend to apply various interpretations to a specific framework. DevOps is no exception. Additionally, when referring to DevOps, considering perspectives from an individual, team, and the entire organization can sometimes make it unclear how various components interact with each other.

We will review the basics of DevOps, clear up misconceptions, and touch on some of its typical practices. Now, before we dive into what DevOps is, let’s talk about how things used to be in the past.

Background on DevOps

Back in the day, software was essentially something you installed. So, for a product development team, all you needed were engineers who could develop and test it. Speaking of testing, it was all about squashing bugs before the release. Just imagine...

Developer experience – A strategy for developer excellence

Developer experience, the term, goes beyond mere user experience and encompasses how developers within a DevOps team can be productive and satisfied with their work. This also works as an organizational strategy to make DevOps successful. If engineers are happy, there are no silos within the organization, and if the communication flows well, your DevOps will succeed. In that regard, GitHub is basically a platform for maximizing the developer experience, and Git is the means to that end:

When you look at individual tools within the realm of DevOps, they may seem small. However, when viewed from the perspective of sustaining and achieving DevOps success, the connection between developer experience and how to use Git and GitHub becomes significantly stronger. Because that is where the essential...

Git – Where code collaborations begin

Managing code changes is a sophisticated challenge. Various team members continuously contribute to a unified code base that must remain functional at all times.

Git has transformed how software development teams work together. By being distributed and offering the ability to create branches, Git has become a vital asset in the DevOps toolbox. A branch is essentially a separate line of development, like a parallel universe, where you can work on new features or fix issues without affecting the main project. This enables teams to focus on multiple aspects simultaneously, making the development process more efficient and adaptable to rapid changes and rapid software delivery, a key requirement in a DevOps environment.

Git is more than just a tool for tracking changes in code—it is a catalyst for change within organizations. By providing a reliable way to collaborate, Git promotes better communication among teams. This aligns well...

GitHub – The AI-powered developer platform

GitHub is the AI-powered developer platform to build, scale, and deliver secure software.

GitHub is often thought of as just a repository service, or sometimes as a repository service with attached CI/CD functionality. However, GitHub now offers a platform that covers the entire development life cycle, from writing applications to building and releasing. GitHub serves as the foundational platform for DevOps collaboration and automation. Through the lens of developer experience, it is the hub for InnerSource initiatives and houses code essential for platform engineering. Furthermore, this is empowered by AI. Whether you are writing code or reviewing it, GitHub’s AI supports you in various scenarios.

The capabilities of GitHub can be divided into five main categories: powered by AI, collaboration, productivity, security, and scale. Let’s look at each one in turn.

Powered by AI

The world is undergoing a transformation...

Summary

This chapter embarked on a journey to explore how DevOps revolutionizes the way we develop software. We talked about the importance of developer experience as a strategy for providing the best work environment in a DevOps team. We also delved into Git and GitHub, the backbone for collaboration in a DevOps setting.

Everything is connected and for a reason. The need for DevOps, the reasons for using Git and GitHub, and the importance of culture in shaping an organization’s people, processes, and tools—all of these elements are interlinked. They collectively shape the form of a developer experience strategy, enabling developers in a DevOps team to perform at their best. What you will do will eventually come back to you, enriching you as a developer.

DevOps should be designed to allow for mistakes to occur in fast development. Each misstep is a step toward mastering DevOps, enhancing your skills, and making meaningful contributions to your team and organization...

Has a good review on Git and DevOps practices, but you have to wade through a lot of extra words on the page. Could have been much more succinct and would have appreciated leaning more towards nuts and bolts technical detail.

If you’ve done any coding since roughly 2005, you have probably used Git to manage development and production. “DevOps Unleashed with Git and GitHub” (Packt, 2024) by Yuki Hattori works hard to bring veteran developers up to speed on the new tools. The book includes extensive coding samples, various development strategies, and thoroughly explores the benefits, challenges, and best practices for each approach. A quick read: the book is divided into three sections, starting with Git, excellence in practices, and beyond DevOps. This book makes an excellent reference for developers, system administrators, or project managers who are currently using GitHub. The book begins with a fresh introduction to Git from the command-line perspective, exploring structures, commands and usages. This brings the reader in at a basic level and ensures a familiarity with the approach. One interesting term, and a first for me, was InnerSource, the development tied to a team rather than OpenSource, where all code becomes widely available. InnerSource pillars are described as openness, transparency, prioritizing mentorship, and voluntary code contribution. The second section moves from the command line git to the user interface (UI) associated with GitHub. These reinforce the techniques from the first section with a point-and-click rather than a command-line approach. One of the best parts for me was the thorough overview of GitHub Issues and Projects. If you haven’t used these tools, they address a historical weakness in GitHub with being able to create work to be done and track via a Scrum or Kanban board. The section also covers establishing a GitHub actions pipeline and describes various deployments such as Blue/Green, A/B, canary, feature flags, and others in detail. Like all other actions, these approaches include benefits, challenges, and best practices to take away. Finally, the book discusses DevOps metrics with DORA and Space, and introduces the concept of Ai. GitHub Copilot, as an additional coding tool. Copilot launched in late 2021 and provides an assistant to writing code. The author references some key aspects when using AI such as detailed comments, descriptive naming conventions, thorough documentation and clearly framed problems. While one may prefer using Generative AI, simply telling it to write code to do a thing doesn’t always get the best results. My biggest issue was the DevOps portion fell a little short. The first chapter extensively covers some of the logic around DevOps, and emphasizes the cultural nature. I agree culture is the primary aspect of DevOps, but if culture is the driver, than technology becomes less important. The book’s DevOps approach feels more like framing to showcase Git and GitHub rather than a full unleashing. In full DevOps implementation, the tools matter, but people and processes carry equal weight. Tools also are a needed element but not an exclusive element to reach accelerated delivery. The DevOps SDLC appears, but the three ways of flow, feedback, and continuous improvement and the CALMS (culture, automation, Lean, Metrics, and Sharing) are conspicuously absent. Agood example might be rather than simply mentioning how Git supports DevOps, show what a full unleashing looks like to the author. Overall, “Devops Unleashed with Git and GitHub” does a much better job in describing the tools than truly unleashing DevOps. That said, this is an excellent reference for those using Git or GitHub for their current development needs. If you are working with either of those tools, I recommend this as a reference and a good introduction to some new capabilities. If you are just starting into coding, this is an excellent place to pick up some core skills.
