Did You Know?

On any normal day on GitHub.com:

  • Around 80,000 public repositories are updated
  • Almost 4,000 people fork a repository for the first time
  • 7000 people push their first-ever repository to GitHub.com
  • Nearly 4,000 people create their first pull request
  • 30,000 issues are created on GitHub.com
  • 4,000 people join GitHub.com
  • 12,000 pull requests are created

Something more amazing:

  • There are over 1.7MM developers who use GitHub
  • Over 3 million software repositories are hosted by GitHub

The tagline of GitHub says: where the world builds software.

Git, in general, is a DevOps tool that is used for source code management. Before going deep, let us look at what happened before using Git:

The team of developers used to submit their code to the central server without keeping a copy for themselves. So they couldn’t track the changes made to the original document. There used to be no interaction between the developers.

Now, when we have Git:

Now, every developer has his/her own copy of the code in their local system, so any changes made to the code can be tracked by others. In this way, regular interaction is developed between the developers.

Later in this article, you will get to know how rewarding taking a Git basics course can be if you are willing to make a career in DevOps. A career in DevOps can definitely be a dream career because:

“Although many organizations are in the experimentation stage with single or multiple pilots, they all are transitioning toward DevOps across their entire enterprise.”

Git Overview

When the development and operations team work together, it is referred to as DevOps. There are some tools in DevOps like Subversion (SVN), TFS, and Version Control System(Git).

So, Git is a version control system that is used for tracking changes in computer files. Git is an open-source distributed version control system meant to handle projects of all sizes and that too with desired speed and efficiency. Generally, Git is used for source code management in software development. It forms an essential part of DevOps which enables non-linear workflows in a distributed manner by offering data assurance so that top-quality software can be developed. 

As far as DevOps is considered, there is a developers and operations team working together. They work in isolation and save their files on shared folders. Git provides a shared workspace to all the team members, thereby making all of them capable of tracking the changes and integrating the final product without any conflicts.

This is because each of the team members gets notified about the changes or modifications made by other members. Eventually, a good collaboration is established between the developers. Your time and effort are saved because it makes visualizations easy.

Since it is easy to learn, it is a favorite tool for developers. Its attractive features include economical local branching, staging areas, and multiple workflows. Developed in 2005 by Linus Torvalds(who is also the famous creator of the Linux operating system kernel), this tool was developed with performance, security, and flexibility in consideration, in addition to being distributed. Distributed here implies that rather than providing one single space for full version history, Git provides and maintains every developer’s working copy of the code, which is also a repository that contains a complete history of all the changes made to it. 

The user interface of Git is almost similar to other version control systems or VCSs, apart from the fact that Git looks at the information in a different way. The other VCSs think of the data they store as a set of files and modifications made to them over time. On the contrary, Git considers data like a series of snapshots of a miniature file system. Every time a developer saves the state of his/her project, Git clicks a picture of what all the files appear to be at that moment and saves a reference to that snapshot. 

Git – A DevOps Tool 

When you Google the term Git, you will find that it is most of the time introduced as a DevOps tool. So, how can DevOps work without Git? the very first line that introduces Git goes like “Git is one of the most widely used version control systems used in DevOps.”

There are a staggering number of software projects that rely on Git for version control. As far as DevOps is considered, DevOps is involved in providing cultural philosophies, tools, and practices that bridge the gap between the Development and Operations team, eventually facilitating continuous development, integration, and deployment. 

The image above makes it clear that there is continuous development, continuous integration, continuous deployment, and continuous control in DevOps, which enables a company to deliver services and applications at a faster pace. 

The very first phase of DevOps is continuous development, where planning and coding take place. Git plays a crucial role in this phase as you need a source code management tool to package the code into an executable file so that the developers can forward it to the next phase. 

The tasks that were manual and took so long to execute, DevOps emphasizes automating those tedious tasks in software development. Here, Git, which is a version control system, enables all of the developers to possess a copy of every version of the source code on their local computers/systems. With copies of their own, developers can update their local repositories with new data from the central server. Then, the principal repository reflects those changes. 

Git facilitates distributed non-linear workflows allowing effective collaboration between the development and the operations team. 

One of the best practices involved in DevOps is the version control system. When large enterprises are considered, the projects generally involve multiple teams, where Git becomes essential as it helps in tracking the modifications/changes made by each team. The accessibility of Git repositories enables teams to communicate easily, eventually making error identification quicker and letting you produce more stable codes. 

The Bottom Line

You probably have had an idea of how crucial Git is when DevOps is considered. To make your career shine in the DevOps domain, taking up an online training course from an accredited institute can be of great help.

Since most enterprises are adopting DevOps, and Git is the most powerful DevOps tool for version control, getting trained makes you a preferred candidate for recruiters.
