What is Version Control?
Version control, also known as revision control, source control, and source code management, is a software engineering practice that involves controlling computer files and versions of files, primarily source code text files, as part of software configuration management. Version control systems are software tools that assist development teams in tracking changes to source code, enabling faster and more intelligent work in a sped-up development environment, particularly beneficial for DevOps teams, as they reduce development time and boost deployment success rates.
Version Control Overview
- Views old versions.
- Enables file to revert to the previous version.
Benefits of Version Control
- Create workflows
- Work with versions
- Code together
- Keep a history
- Automate tasks
What is Git?
Git, a distributed version control system, was initially released in 2005. It is currently one of the most popular version control systems in the world. Each developer has a complete copy of the repository, including its history because Git is a decentralized version control system. In essence, developers can modify their copy of the codebase and then push those changes to a central repository, where their code is merged with the modifications made by other users. Git manages changes through branches and merging which provides greater flexibility and a more powerful workflow.
According to Wikipedia, "Git is a distributed version control system that tracks versions of files. It is often used to control source code by programmers collaboratively developing software".
According to Atlassian, "the most widely used modern version control system in the world today is Git. Git is a mature, actively maintained open source project originally developed in 2005 by Linus Torvalds, the legendary creator of the Linux operating system kernel".

Advantages of Git
- Works locally.
- Its goal is to prevent a single point of failure.
- Effectively manages merging from multiple contributors.
What is SVN?
Apache Subversion (often abbreviated as SVN) is a version control system, released in 2000. It was developed as an alternative to CVS (Concurrent Versions System). SVN is a centralized version control system that uses a central repository to commit/store all changes. Developers can check a working copy from the central repository, make modifications, and then commit those changes back to the central repository.
According to Wikipedia, "Apache Subversion (often abbreviated SVN, after its command name svn) is a version control system distributed as open source under the Apache License. Software developers use Subversion to maintain current and historical versions of files such as source code, web pages, and documentation. Its goal is to be a mostly compatible successor to the widely used Concurrent Versions System (CVS)".

Advantages of SVN
- Takes an easier approach.
- Stores huge binary files efficiently.
Difference between Git vs SVN
Now, let's see the difference between Git and SVN.
| |
Git |
SVN (Subversion) |
| Architecture |
Distributed Version Control System (DVCS) |
Centralized Version Control System (CVCS) |
| Branching & Merging |
In Git, each developer has a complete copy of the repository, including its history. |
With SVN, there is only one main repository, where developers can checkout the working copy and commit changes to this central repository. |
| Data Integrity |
Git uses SHA-1 hashes to ensure data integrity. Each commit is a snapshot of the entire repository. |
SVN uses a centralized approach where the server ensures data integrity. |
| Collaboration & Code Review Process |
Best for agile, collaborative code review processes with multiple tools like GitHub or GitLab that integrate well with it. |
Best for traditional, hierarchical code review processes, but integration with review tools is less seamless. |
| Performance |
Git is generally faster due to the local execution of operations such as commits, branching, and merging. |
SVN is typically slower due to the communication with the central server, especially for large repositories or slow network connections. |
| Learning Curve |
Git's strength and flexibility come with a steeper learning curve, particularly for new users. |
Generally easy for beginners to understand but may become complex with bigger projects or teams. |
| User Interface |
Git UI is not as impressive as SVN. |
SVN has a simple, better user interface than Git. |
In conclusion, both Git and SVN are powerful version control systems, but each has its own advantages and disadvantages. Git is often chosen due to its distributed structure, speed, and flexibility, making it suitable for a variety of teams and projects. Due to its centralized methodology, SVN can still be an excellent choice for projects that value centralized control and simplicity.
