Git is a free and open-source distributed version control system. It was designed to handle everything from small to extensive projects with speed and likewise, with efficiency.
Git is easy to learn and has a tiny footprint with lightning-fast performance. It outclasses SCM tools like Subversion, CVS, Perforce, and ClearCase. Git has features like cheap local branching, convenient staging areas, and also multiple workflows.
A staggering number of software projects rely on Git for version control, including commercial projects as well as open-source. Developers who have worked with Git are well represented in the pool of available software development talent. In addition to this, it works well on a wide range of operating systems and IDEs (Integrated Development Environments).
Advantages of Git
One of the most significant advantages of Git is its branching capabilities. Unlike centralized version control systems, its branches are cheap and easy to merge. This facilitates the feature branch workflow accessible with many Git users.
Each developer gets a working copy that points back to a single central repository. However, it is a distributed version control system. Instead of a working copy, each developer gets its local repository, complete with a full history of commits. Distributed development also makes it easier to scale your engineering team.
Many source code management tools enhance core Git functionality with pull requests. A pull request is a way to ask another developer to merge one of your branches into their repository. This not only makes it easier for project leads to keep track of changes but also lets developers initiate discussions around their work before integrating it with the rest of the codebase.
In many circles, it has come to be the expected version control system for new projects. If your team is using Git, odds are you will not have to train new hires on your workflow, because they’ll already be familiar with distributed development.
The ultimate result of feature branches, distributed development, pull requests, and a stable community is a faster release cycle. These capabilities facilitate an agile workflow where developers are encouraged to share smaller changes more frequently. In turn, changes can get pushed down the deployment pipeline faster than the standard of the monolithic releases with centralized version control systems.
To Wind Up
The Git feature that makes it stand apart from nearly every other SCM out there is its branching model. It allows and encourages you to have multiple local branches that can be entirely independent of each other. The creation, merging, and deletion of those lines of development takes seconds.
When you push to a remote repository, you do not have to push all of your branches. You can choose to share just one of your branches, a few of them, or all of them. This tends to free people to try new ideas without worrying about having to plan how and when they are going to merge it in or share it with others. There are ways to accomplish this with other systems. However, the work involved is much more complicated and error-prone. It makes this process incredibly comfortable, and it changes the way most developers work when they learn it.
