SCM an acronym that stands for Source Code Management is an integral part of any development project in the current IT world. Same is the case with the DevOps culture, where storing the work results and sharing the details with the colleagues is an essential part too. Source Code Management and Version Control Systems in any project ensures all the members of a team stay on top of the source code changes. Having said that, a common mistake that most people do is to assume that the Source Code Management tool will by itself solve all the SCM problems or support the SCM requirements of the project. To break the jynx, it is not the tool itself that solves the problem but the application of that tool resolves these SCM related issues. How you apply the SCM tool to your development environment is called the usage model, or SCM process. It is this model or process that will in part determine how successfully you address your SCM issues.
Source Code Management tools are the crucial ones that make or break the effort put in by multiple developers, in coordinating parallel work on similar features and integrate these to make the final product. In addition to the actual source code, it also manages the configuration files as well. The application deployment can be facilitated when the configuration of cloud services are under the version control.

In this section, we will try to look in to the number of options that we have in the space of Source code management. There are multitude of options available but we will go through the best of the best that caters needs and requirements in various DevOps pipelines. Alongside going through the tools themselves, we will also take a brief look into the advantages that these tools will bring to the table as well. Let us not take any further time on pondering around the introductions any further and go through the tools and its advantages:
1. Team Foundation Server (TFS):
Coming to the next tool under discussion from the exhaustive list of paid DevOps tools, comes the next – Team Foundation Server (abbreviated with TFS) is a Microsoft produce to cater the Source Code Management requirements. It works pretty well with both the ways of development, namely Agile software development and also the Waterfall model development. Apart from the Source Code Management capabilities, it also caters to automated builds, Lab Management, Test and Release management capabilities. Not to mention that it covers the whole application development lifecycle and enables all the possible DevOps capabilities.
Following are some of the advantages of using Team Foundation Server (TFS), let us now take a look at each and every one of them:

It manages a centralized database and also along with it a master repository of all possible file versions.
Helix Core clients are classified into 5 categories (based on the way that they connect to the Code repository): GIT, Command, GUI, Web and Plugin. Perforce system can make a portion or all of its content made available as GIT repositories. Users of GIT and of other clients can make use of this and work with the same file content and history. GIT commits will be further be visible to others as Perforce Changelists and the other way round for others.

Subversion is an open source version control system (VCS) which manages files and directories and the corresponding changes made to them over the project’s life cycle. By that, there is always an opportunity to recover the older versions of the files, if there are any issues with the current code and also let you check on the history of your code. It allows users from different geographical locations access the same code and work on the same code in a collaborative way.
There are some version control systems that are also known as Software Configuration Management (SCM) systems. These systems are tailor made specifically to understand a specific programming language or provide build tools or build mechanism for the software development. Luckily Subversion, is not one of these systems. It is a general system that can be used to manage any collection of files which could be source code or general documentation as well. Subversion has enjoyed and continues to enjoy widespread adoption in both the open source arena and the corporate world.
Following are some of the advantages of using Subversion, let us now take a look at each and every one of them:

Mercurial is a free and also a distributed source control management tool that handles projects of any size efficiently. It is a cross platform solution as it is available for Windows, FreeBSD, Mac OS X and Linux Operating systems. The Mercurial project was initiated just in the same era as was the time when GIT was getting developed. As a matter of fact, GIT was adopted for version control for Linux projects and Mercurial was adopted by many other development projects per se. Mercurial is still under active development and the latest release that we have is release 3.8.4 as on 1st July 2016.
Following are some of the advantages of using Mercurial, let us now take a look at each and every one of them:
As far as GIT is concerned, it is known to have the smallest footprint possible and has lightning fast performance. Another advantage over and above what is already mentioned is that it is easy to learn as well. Git outclasses the other SCM tools in the family as like Subversion, CVS, Perforce and ClearCase with features such as local branching, provision of convenient staging areas and varied number of workflows. It is by far the most widely used version control system that is in use in the world today. Git being mature enough to handle most of it, also has an actively maintaining open source community.
Not just that, there are a numerous number of projects that are relying on Git as we speak including the commercial and open source projects. Git works in varied number of IDEs available these days and is known to work in all the major operating systems. Rather than holding all the version history of the software at a common place like Subversion or CVS – Git ensures that every developer’s working copy has the code which also contains the full history of all changes. Git is also designed keeping in mind the performance, security and flexibility in mind.
