Linux is a popular, open-source operating system originally designed as a cheaper UNIX alternative. With the ability to quickly deploy stable, secure, and agile servers across virtualized environments, it quickly became the OS of choice for many IT professionals.But the rise of more user-friendly alternatives such as Windows has pushed Linux into a largely supporting role. Combined with a greater focus on mobile-friendly app development and the rise of cloud-based enterprise IT. It’s worth asking the question: Is it worth learning Linux and earning the Linux+ certification in 2020?

Who’s Using Linux?
While Windows remains the most popular front-line business operating system, many enterprises leverage Linux to handle more resource-intensive or complex tasks that aren’t well-suited to Windows deployments. Huge companies like Google, Twitter and Facebook all run Linux-based solutions that have been customized to meet their business needs — since the code is open-source, organizations can both repurpose existing code instead of building their own, or adapt current offerings to align with business expectations.Also worth noting? Historical competitor Windows now recognizes the value of Linux kernels — the essential “center” of any operating system — and now supports a full Linux kernel1
in Windows 10
. With businesses now expecting ease-of-interoperability across IT infrastructure, operating systems, and cloud solutions, tech providers can no longer afford to rely on proprietary tools that don’t play nice with other IT solutions. As a result, Linux is gaining ground.
Why Should I Learn Linux?
To ensure Linux deployments meet C-suite expectations, align with other IT objectives, and deliver ROI, companies need trained professionals capable of designing, implementing, and troubleshooting new Linux solutions. From selecting the right distribution (distro) — options like Ubuntu, Fedora, and KaOS are all popular choices — to aligning new Linux deployments with existing technology stacks, there’s a growing need for Linux experts in the enterprise.While many IT professionals have some experience with Linux in-situ or through post-secondary training, there’s no way to quantify or standardize this type of IT training
and ensure IT pros can deliver on deployment promises. To bridge the gap between lived experience and empirical ability, many enterprises are now looking for certified Linux professionals. Designations such as Linux+ indicate that IT staff have both the necessary training and accreditation to effectively implement Linux solutions at scale.Linux+ certified professionals bring critical skills to the technology table, including:
- Hardware and system configuration — Experts can easily configure kernel modules, network parameters, and virtualized environments.
- System operation — Linux+ professionals, can leverage all facets of this OS to deliver software and services at scale.
- Automation and security — Certified Linus pros could automate key tasks using BASH scripts, deploy version control with Git, and develop effective authentication and firewall strategies to protect key assets.
How do I Learn Linux?
The best way to start learning Linux is with hands-on experience. Once you’ve spent six months (or more) working in IT with Linux deployments, consider earning your Linux+ certification. While it’s possible to train for the Linux+ exam on your own, the sheer volume of information available makes it difficult to ensure you’re targeting the right concepts and have the practical knowledge necessary to translate experience into answers.In-depth courses
from well-known online providers can give you a leg up on Linux+ learning with training across key topics such as:
You’ll also cover critical skills, including:
- Hardware setting configuration and booting
- Disk and library management and design
- Script writing and basic SQL data manipulation
- X11 setup and display
- System troubleshooting across network settings and services
To earn Linux+ certification, you must complete the XK0-004 exam, which consists of 90 questions across performance-based, multiple-choice, and fill-in-the-blank formats. You have 90 minutes to complete the exam and must score 720/900 or better to pass.
What Jobs can I Get with Linux Training?
Armed with Linux+ certification, you’re ready to tackle virtual environments, deploy essential services and bridge the gap between existing solutions and new Linux deployments — but what does this mean for potential job prospects?While almost any role benefits from Linux knowledge, popular Linux-focused jobs include:
- Technical support specialists — System backends invariably run on Linux, requiring trained professionals to troubleshoot and manage.
- Network engineers — Designing new networks means integrating key Linux operations and features.
- System administrators — Managing systems at scale demands the ability to handle both Windows and Linux-based environments.
- Security engineers — Integrating security across disparate networks means deploying custom-built Linux solutions to safeguard critical data.
Linux training also helps pave the way for more advanced certifications such as Certified Ethical Hacker
(CEH), Certified Information Systems Auditor
(CISA), and the Certified Information Systems Security Professional
(CISSP).While Windows remains the most popular form of many business IT environments, Linux provides the function. Certified Linux+ professionals are now in demand, making this designation well worth the time and effort in 2020.
