What are SCM tools?
The term "SCM" stands for Source code Management, a basic but essential part of any project developed in the current IT world. It is a kind of software that the developers usually use to manage their source code. It plays a vital role in the process of software development because it ensures that every member of the team stays on the top of source code changes in an ongoing project.
There is a common doubt in the users that they think it is the source code management tool that solves all the source code management problems and full fills the source code management requirements of a particular project.
To clear this doubt, we must know that it is not the source code management tool that solves all SCM related problems by itself, but the application of that tool that solves all kinds of SCM issues. So it is also essential that we use the source code management tool for our software development environment.
The way we apply the source code management tool to our development environment is known as the "usage Model." It is the usage model that decides how precisely the user addresses his SCM issues.
The "Source Code Management tools play a significant role as it may make or destroy all the efforts put in by several developers that are working continuously in side by side manner on the similar features to make the desired product on time. It also manages other files like configuration files. When the configuration of cloud services is under version control, application deployment can be facilitated.
Importance of the Source Code Management tools
Why we need the Source Code Management Tools
When several developers are working within a shared codebase, it is normal to make changes in the shared code. However, several times these features may also belong to the same model, which means they are from the same module. So, sometimes a developer working on feature X can make some edits which can be found later that other developer B working on feature Y has some conflicting edits. It was considered the most significant nightmare scenario before the adoption of source code management.
Suppose the developers make changes typically to text files directly and places them around to a remote location using File Transfer Protocol(or FTP) or any other protocols. Developer A would make changes or edits, and developer B would unknowingly and unwillingly save his work on developer A's work and restores (or wipe out) the edits done by the developer A. Here the SCM plays a role as the protection mechanism against this kind of scenario called Version Control.
The source code management introduces the version control safeguards to avoid the loss of work caused by the overwriting conflicts and these safeguards work through tracking every developer's every change, address the area of conflicts, and avoid the overwrites. Once the overwriting areas become known, the source code management then communicates all these points back to the developers to ensure that they can safely address and review them.
This mechanism of conflict prevention has a side effect that provides passive communication for the development team. The Developer team can monitor and discuss about the work in progress monitored by the source code management. The SCM keeps tracks of the entire history of modifications made to the base code, and this allows developers to review the edits or changes that may bring the regressions or bugs.
Let's take a look at the benefits of Source Code Management Tools.
Types of Source Code Management (SCM) DevOps Tools:
In this section, we will focus on the number of source code management options that are currently available. There are many types of Source Code Management Tools available in the market, so here we will discuss only those that come under the top list. We are also going to discuss their advantages, which bring these tools on to the table.
1. Bitbucket Server:
The Bitbucket server is a combination of the web interface and the GIT server offered by the Atlassian. In general, it is a web-based hosting solution that specifically targets such projects that use either Mercurial or GIT version control systems. This tool has been developed specifically for developers' professional teams as it allows them to code and enables them to manage and collaborate on the GIT project.
Advantages of Bitbucket Server
These are some following advantages of using the Bitbucket Server:
2. Team Foundation Server (TFS)
The Team Founder server (abbreviated with TFS) is one of Microsoft's products, and it is developed by Microsoft to fulfill the essential requirement of source code management.
It works quite well for what it was designed. It also works very well for both software development models: the waterfall development model, Agile software development model. Besides, the SCM (or Source Code Management) capabilities, it also fulfills the several other requirements such as Test, Releases Management capabilities, Lab Management, and automated builds.
There is no need to mention here that it also covers the complete application development lifecycle and enables a considerable number of possible DevOps capabilities.
Advantages of Team Founder Server
These are some following advantages of using the Team Founder Server(or TFS):
The Subversion is open-source VCS (Or Version Control system) that manages several tasks such as managing directories, files, and the corresponding changes made over the project's life cycle. It also provides us an opportunity to restore (or recover) the several older versions of our files if we had some issues with the current version of files (or current code). It also enables us to check the history of our written code. The TFS allows its users to access the same code from the different geographical locations and let its users work collaboratively on the same code.
As we already know, some VCS (Version Control Systems) are also known as the SCM (Software Configuration Management) systems. It is a type of general system that can be used easily by the users to manage several different collections of the files, which could be files of the user's source code or the software's documentation as well. Subversion adoption is still in progress among users, and its adoption continues to be widespread in both the corporate world and open-source sectors.
Advantages of Subversion
These are some following advantages of using the Team Founder Server (or TFS).
Kallithea is also one of the open-source Socure Code Management Tools that are freely available and supports the leading version control systems such as the Mercurial and GIT. It is both a powerful and fast tool that has a built-in push and pull server, code review, and also offers the Full-text search. It also works seamlessly on both types of protocols such as HTTPS(Hypertext Transfer Protocol Secure), HTTP(Hypertext Transfer Protocol) with another built-in feature of the authentication/ permission system, and Authenticates via the capabilities of LDAP or Active Directory, also provides some APIs for easier integration with the external world.
We can clearly say that the Kallithea is quite similar to Bitbucket or Github in more than one way, but it has also proved that it is better than others with its feature as a standalone hosted application on our server.
Advantages of Kallithea
These are some following advantages of using the Kallithea. Let's try to discuss each one of them:
The Mercurial is one of them that is available for free. It is also a distributed source code management tool that can handle the projects of any size seamlessly. It has another significant feature: it is cross-platform that means it is available for almost every type of operating system, such as Linux, FreeBSD, Mac OS X, and most used Windows. The development process of the Mercurial was begun in the meantime when the GIT was already in the development process. If we talk about the GIT, it was adopted for the version control basically for the Linux projects. On the other hand, the Mercurial was also adopted for Linux projects, and several other projects as well.
Advantages of Mercurial
These are some following advantages of using Mercurial:
One of the significant advantages of using Mercurial is its ability to track all changes and the ability to allow the user to roll back to a targeted version of the current files on which the user is working on.
6. Helix Core Version Control
This is the next tool in our list. It is actually based on the versioning engine that provides power to those customers, who usually see file-level asset management, which is lightning-fast. Its core knew as Perforce Helix, that is one of the version control engines that are usually used for large scale development environment. It manages the centralized database, also along with it a master repository of every possible version.
The Helix Core clients are usually categorized into five categories based on how they are connected to the code repository. The name of the five categories is Plugin, GIT, Web, Command, and the last one is the GUI.
The Perforce system is able to make available it's all content as the GIT repositories or make a portion. The users who are using the GIT and the users who do not use GIT can use this and work with the same file content and history. Commits of GIT's will be further visible to the others as the Perforce Changelists.
Advantages of Helix Core Version Control
These are some following advantages of using the Helix Core Version Control:
GitLab is yet another repository management tool hosted on a free hosting service called GitLab.com. Besides this, it also provides the GIT repository Management function with several features such as code reviews, access control, bug tracking, etc.
The GitLab Ci was apparently unified with the GitLab, also very easy to use for linking the project by using the APIs of the GitLab. The GitLab is build using Ruby language, but the Go language is also used in it where it is required. It can execute several types of operating systems such as FreeBSD, Docker, Windows, Osx, and Linux.
Advantages of GitLab
These are some following advantages of using the GitLab:
The Gerrit is another one of the GIT-based Source code management tools available in the market, but it manages a lot more than just reviewing the source code.
The Gerrit is one of them which are freely available for all users. It is also an open-source web-based team code collaboration tool.
Advantages of Gerrit
These are some following advantages of using the GitLab. Let's discuss each one of them:
A considerable number of developers possibly already know about Github. Still, even after that, many developers also get confused about it when they are asked about the Github. The GITHUB is one of the powerful source code management tools (SCM tools), which helps the team get together and solve the occurring problems with changing time by making the necessary changes into the existing code.
It is an impressive Source code management tool, which is also based on the Git, just like several other tools that are also the best place to share code with friends, colleagues, etc. They learn from each other along the whole way and pass the ideas forward.
The GITHub has excellent user acceptance and several other source code management tools, which has been available in the market for a long time.
These are some following advantages of using the GIT. Let's try to discuss each one of them:
