In terms of cloud computing and the development of container orchestration, the role of a DevOps engineer has dramatically changed as well. Enterprises no longer look for professionals who can automate deployments. Now they need specialists who can work with the operating system which forms the basis for most of cloud infrastructure. It means that having decent Linux skills is now one of the key prerequisites for entering the area of DevOps, cloud engineering or platform administration. No matter whether your app runs on AWS, Microsoft Azure, Google Cloud or even Kubernetes clusters, the chances are that your infrastructure is based on Linux.

All of the mentioned cloud technologies require the profound knowledge of Linux to operate correctly. Configuring servers, automating processes, securing and troubleshooting production – whatever you do, the knowledge of Linux is involved in all of the steps of working with the app. The professionals who have deep knowledge of Linux are better at deploying apps, automating their work and resolving infrastructure problems than the specialists who just use graphical interfaces.

It seems scary to the beginners due to the diversity of technologies that are to be mastered but Linux knowledge will ease your way of learning cloud platforms, Kubernetes, automation tools and CI/CD workflows. Instead of trying to remember everything, it’s better to understand how Linux operates and how it fits into the contemporary cloud environment.

This guide covers the reason why Linux continues being the core of cloud computing and Kubernetes, the essential skills that every DevOps engineer should obtain and how mastering Linux knowledge can be helpful in the long run.

Why Linux Is the Foundation of Cloud and Kubernetes

A great portion of cloud infrastructure is powered by Linux. Public cloud providers, company’s datacenters, Kubernetes, and other cloud native tools use Linux because of its reliability, security, flexibility, and good performance. Therefore, individuals who interact with cloud technologies every day do it with Linux without even knowing about it.

In order to deploy an application in the cloud, one needs to run it on virtual machines and containers that are implemented using Linux. Entire Kubernetes clustering technology is built around namespaces, cgroups, process isolation, and other concepts of Linux. The knowledge will help you to troubleshoot and optimize your application.

For those who have decided to become a specialist in IT domain, the best recommendation is to take a Linux course for beginners in order to proceed with studying advanced cloud technologies. Knowledge related to file systems management, users administration, network configurations, permission management, shell scripting, and process management will assist you to comprehend containerization and orchestration.

One more thing about using Linux as an operating system is its consistency. Irrelevant whether you administer on-premises server, cloud virtual machine, or Kubernetes node, the concepts of Linux administration will stay the same. Thus, one can minimize the learning curve when working with cloud technologies.

Individuals who know Linux well will be able to adopt to the new technologies as they know how to work with the operating system through application. In other words, one will not need to learn everything from the beginning.

Linux and Kubernetes: A Powerful Combination

In the present day, Kubernetes is considered the ultimate choice for the orchestration of containerized applications, but it is required to have a good knowledge of Linux, because all Kubernetes clusters run on Linux nodes and application runs there. Thus, without knowledge of the fundamentals of Linux, troubleshooting of Kubernetes problems is going to be much more difficult.

Although a professionally constructed kubernetes course gives you knowledge about basic notions of Kubernetes such as Pods, Deployments, Services, ConfigMaps, and managing of clusters, it is extremely important to know how everything happens under the hood. In this case, you will be able to analyze resource usage, solve networking problems, check system logs, work with storage and tune your containers.

This approach is especially effective for problem solving in a production environment, as you should not only examine Kubernetes’ CLI commands, but also the underlying operating system in order to find out what causes the problem.

Thus, by learning either Linux first and then Kubernetes or vice versa, you will build a powerful skillset that is highly demanded in modern DevOps world.

Why Every DevOps Engineer Needs Strong Linux Skills

Automation, collaboration, and continuous delivery – all core concepts of DevOps – would be impossible without a stable OS. The lion’s share of cloud servers, containers, and enterprise applications run on Linux. That’s why DevOps engineers devote a large part of their time to Linux environment.

The main benefit of Linux education is automation. Shell scripts help automate system administration processes, manage server configuration, automate deployment, take care of backups, and even carry out system maintenance without manual intervention. This improves efficiency and minimizes human factor impact.

Linux education contributes to better troubleshooting skills. In case of problems with applications, DevOps engineers have to analyze system logs, system processes, file permissions, and system resource usage to find the root cause of an issue. Understanding how Linux operates in such cases helps solve the problem.

That’s why many professionals prefer to combine Linux education with Cloud Computing Training. Not only does it allow them to practice working in a cloud infrastructure, but it also helps understand how Linux servers behave in AWS, Azure, and Google Cloud infrastructure. As more and more companies migrate their applications to the cloud infrastructure, DevOps engineers with good Linux skills become even more desirable.

Building Cloud-Ready Skills with Linux

The development and delivery of applications has been completely changed due to the innovation of cloud computing. Instead of building and managing data centers, modern business needs scalable cloud infrastructures which provide computing power as needed. While cloud computing has made managing infrastructure easier, Linux still plays an important role in cloud.

The use of Linux in most cloud-based virtual machines, container services and application servers is based on its stability, robustness and flexibility. Engineers with solid Linux knowledge will have an easy time working with cloud computing and will be able to manage infrastructure easily.

Also, having the knowledge of Linux makes understanding of such concepts of cloud computing like virtual machines, storage management, networking, security groups, load balancing easier. All of these technologies help in achieving availability and scalability of applications.

There are several cloud computing programs which have a structured approach and teach Linux Administration. Such programs understand the importance of Linux in the world of cloud computing and that it is not a completely separate thing.

Developers with cloud-ready Linux skills can take part in infrastructure automation, application deployment, disaster recovery planning and systems optimization. Some of the reasons why they become an integral part of DevOps and Cloud Engineering teams.

Practical Linux Skills Employers Look For
