Excerpt: Linux is a versatile kernel that is omnipresent. It powers multiple servers, pipelines, clouds, and much more. However, it might be challenging for rookies to understand Linux. One of the major advantages of Linux is that it is open-source, which means anyone can take part in the development of Linux.
One of the major goals that both Linux and DevOps have, similar to each other, is scalability. It is one attribute that enables an upper to deliver software fast without sacrificing the developer's code quality. This one attribute makes Linux the best option for DevOps.
The community of developers is enabled to collaborate on making the operating system quite effective and efficient. Most importantly, one needs a powerful and dependable internet connection for smooth operation. In this article, we get an insight into how Linux is a perfect option for DevOps.
What exactly is Linux?
Linux is one of the commonly used Operating systems. It is an open source and free platform that one can avail of for a General Public License. Like every operating system, Linux acts like a mediator between the hardware and software of the device. This Operating System is responsible for the regulation of the hardware and is used to satisfy the requirements of the software.

What is DevOps?
DevOps is a way of integrating software development as well as IT operations. The basic concept of DevOps includes integrating, automating, consistently collaborating, and freely communicating to provide software swifter than ever.
Below are some of the reasons why Linux is a perfect option:
1. Linux is completely free of cost
As opposed to Windows and Linux, AIX does not cost you anything. The distinctions between enterprise Linux and distros like RedHat are quite minimal if we compare it with the free edition. You can operate it at home and make the same application in an enterprise setup. This will tremendously help you in building technical skills in your resume.
2 .It is easily customizable.
Its adaptability is the most essential and famous attribute of Linux that sets it apart from the rest. You can seamlessly run it from any device and alter every aspect of the OS, such as the way your workflow has a proper configuration, the applications it runs, your preferred DevOps security standards, and the server environment. This assists the DevOps environments, which are dependent on fluid processes.
3. Linux has great scalability.
Scalability is quite essential when it comes to the sustenance of DevOps operations. The capacity to expand without the need for upgradation of your system is very important. There is a need for a lot of time and monetary investment. Fortunately enough, Linux has great scalability as compared to its counterparts. The Linux kernel can seamlessly tackle humongous quantities of memory and the capacity of a hard disc drive. The best thing about Linux is that it can run on anything, from laptops to IoT devices, and fluctuates the OS to fit your needs.
4. Linux has massive popularity.
There is a steady rise in the popularity of Linux. These days, there is a smooth running of Linux on numerous technologies that power products as well as services. It can be mobile phones, social networks, GPS services, the Cloud, or any other product.
5. The command line knowledge of Linux
There is always a presence of GUI on Linux servers, but it does not operate all the time. System engineers have to accommodate manually managing conf files with the VI and access through SSH to the server on port 22. As opposed to those who have adapted to the opening GUI prompts and pressing buttons, those who are devoid of a simple "easy button" find it painless to set up similar things with the use of scripts or programs.
Some of the best Linux options for DevOps
1. RHEL Desktop
Red Hat Enterprise Linux or RHEL Desktop is a Linux Distro for high-performance tasks. This includes Containers for Kubernetes, Dockers, and other cloud environments.
2. Cloud Linux OS
This is a Linux distro made with the help of cloud computing. Since it is based out of CentOS, this Distro is dependable, scalable, and can be connected with other systems.
3. Amazon Linux
A Linux image that is particularly designed for Amazon EC2. It consists of tools that enhance integrations and workflows with platforms.
CentOS is an OS based on Linux, which Red Hat Enterprise inspires. It is also allowed to be suitable with RHEL. One of the salient features of CentOS is that it is a cloud computing that operates free of cost.
5. SUSE Linux Enterprise Desktop
It is a Linux Distro specifically made for desktops. The intelligent AppArmor system that it has enables installing of a firewall on applications.
A Continual Learning Experience
One needs to learn new things and adapt to new kinds of paradigms. This is important to let one succeed as a professional in the ever-changing field of IT development. When it comes to DevOps engineers, they need to follow the road of continuous and consistent improvement. Even if you are a true code ninja who can produce flawless code on demand, understanding and grasping the context of the project in a better way can be helpful. If your team works with Linux, having a fundamental and deep understanding of the operating system will significantly impact how you undertake the activity of designing, developing, and deploying IT solutions.
What are the skills that DevOps engineers must have?
1. Collaboration and Communication Skills
Since DevOps has a fundamental nature, cooperation and communication are crucial for success. These are very important for removing the barriers between Dev and Ops teams, getting teams' goals in alignment with corporate objectives, and fostering a cross-functional culture of DevOps.
2. Noble Thought and great Soft Skills
Just being good at automation and coding would not suffice. One needs to have great soft skills, self-motivation, learning, and flexibility to be a part of DevOps. A professional who is a part of DevOps should not only be a doer but a good listener too. They need to have clarity on the facts relating to DevOps transformation. This transformation involves stakeholder discussions, assessments, a level of understanding of business goals, and the ability to identify improvement areas. All of them need to be driven by collaboration.
3. Security Skills
The rate of risks matches the speed of deployment enabled by DevOps. Because of this limitation, the general strategy that places the concern on security at the end or does not place any concern at all will not be effective. There is an advantage of DevSecOps that integrates security with the SDLC from the outset. Hence having a sturdy DevSecOps skill set will, without question, help you succeed as an expert in DevOps.
4. An understanding of Important Tools
The success of DevOps completely depends on the toolset it has during different phases of the implementation. DevOps have brought in numerous tools.
5. Automation Skills
A strong understanding and a grasp of automation, the core of the DevOps approach, is essential to be referred to as a DevOps engineer. A DevOps engineer should be able to automate every step of the DevOps pipeline. It includes infrastructure and configurations, CI/CD cycles, app performance monitoring, and many others. The ability to use the DevOps toolset, code, and script directly relates to DevOps automation expertise.
6. Strong Cloud Skills
Cloud and DevOps always go hand in hand. The effectiveness of one is completely dependent on the other. DevOps and Cloud also have a major influence on one another. On the one hand, the DevOps method is responsible for driving a process; the Cloud can enable that process by giving out the required platform to test, deploy and release code.
7. Customer-oriented Approach
Any effective DevOps process has the most crucial aim of achieving customer satisfaction. Given this aspect, DevOps professionals should ensure that every task they complete fulfills end-user needs and aligns with company goals. To do this, they must work with many stakeholders, including project managers, testers, developers, and the organization's thought leadership.
8. Testing Skills
Testing is quite crucial to the success of DevOps. Tests must function flawlessly without failure in the DevOps automation procedure. For continual testing to be successful, the location where automated tests are run is crucial.
9. A proactive approach
The professionals in the field of DevOps will need passion and proactiveness towards work which directly reflects productivity.
DevOps is not just a culture but also a technical solution. It will be quite beneficial the better you comprehend a professional, business, or service provider; you need to be quite flexible in your operations, open to change and possess a mix of soft and hard skills if you want to thrive in the journey of DevOps.
