What is Version Control System in Devops?
Version control, also known as source control, is the practice of tracking and managing changes to software code. Version control systems are software tools that help software teams manage changes to source code over time. As development environments have accelerated, version control systems help software teams work faster and smarter. They are especially useful for DevOps teams since they help them to reduce development time and increase successful deployments.
Version control software keeps track of every modification to the code in a special kind of database. If a mistake is made, developers can turn back the clock and compare earlier versions of the code to help fix the mistake while minimizing disruption to all team members.
GIT
Version Control Systems (VCS) have seen great
improvements over the past few decades and some are better than others. VCS are
sometimes known as SCM (Source Code Management) tools or RCS (Revision Control
System). One of the most popular VCS tools in use today is called Git. Git is a
Distributed VCS, a category known as DVCS, more on that later. Like many of the
most popular VCS systems available today, Git is free and open source.
By far, 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 famous creator of the Linux operating
system kernel. 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 and it works well on a wide range of operating systems and
IDEs (Integrated Development Environments).
Git has been designed with the integrity of managed source code as a top priority. The content of the files as well as the true relationships between files and directories, versions, tags and commits, all of these objects in the Git repository are secured with a cryptographically secure hashing algorithm called SHA1. This protects the code and the change history against both accidental and malicious change and ensures that the history is fully traceable.
Git is the best choice for most software teams today. While every team is different and should do their own analysis, here are the main reasons why version control with Git is preferred over alternatives:
