Why Learn Linux? Discover Its Benefits and Career Opportunities

If you still have doubts about why learning Linux is important, this article will clear up any questions.

The system has proven increasingly dominant, especially in cloud computing, an area in which 83% of organizations run Linux on their servers.

This is according to a survey by SUSE.

Companies like Google, Facebook, NASA, New York Stock Exchange, and many others prefer Linux due to factors such as security, hardware flexibility, stability, and cost-effectiveness.

All this prominence means that professionals who master the operating system and its languages have a wide range of opportunities.

Continue reading and understand why learning Linux is a great idea.

Why do companies use Linux?

The choice of Linux as the operating system by companies is not by chance.

After all, its use means keeping operational costs low without losing performance or quality.

See five reasons why big companies, like Google, prefer Linux:

Stability

When we talk about servers, Linux is much more stable than Windows, its main competitor.

This happens because it can maintain constant performance for long periods without major interruptions.

You will hardly ever need to reboot a server running Linux, thus reducing the chances of any kind of damage or loss.

The system's stability is such that it is possible to run countless processes simultaneously without any harm.

In other words, there is also a gain in terms of performance.

Security

Linux is one of the most secure systems in the world largely due to its various environments, which allow the IT team to choose the most effective alternative.

Additionally, because it is an open source platform with a very active community, permissions and code tend to always be up to date, favoring stability for its users.

The presence of viruses and any other type of virtual threat is also rarer, as Linux has a range of features that make it difficult to alter system package data.

Hardware flexibility

Linux is compatible with a wide variety of hardware worldwide.

This flexibility makes the operating system one of the most used in technological evolution, such as in the Internet of Things concept, for example.

Devices that are not computers use the platform, as they can customize their solutions thanks to the customization capability that Linux provides.

With minor changes, cars, appliances, and other products can adapt processes to fit their realities and execute different commands.

Cost-effectiveness

Linux is a free operating system (although some base software is paid), which ensures implementation with almost no cost.

Technical support is also more accessible, as it is a popular platform with countless skilled specialists available to work with its architecture.

And what weighs more is its compatibility.

As we saw, Linux works with almost every type of hardware. 

Therefore, companies don't need to worry about buying new equipment to install on their servers.

In other words, it's significant savings, especially for smaller businesses. 

What is the job market for those who know Linux?

All the benefits that Linux offers make it a highly sought-after platform by companies.

As a result, it can turn into excellent opportunities for those who master the operating system.

Learn about the main career opportunities in the market:

Mobile development

Mobile solutions deliver more dynamism, practicality, and comfort to users and, therefore, continue to gain ground.

Within this logic, devices with Android system dominate the market.

And here's the thing: it's basically a Linux-based software.

In other words, learning Linux trains you to develop apps for smartphones, for example.

Database

Most Database Management Systems (DBMS) perform better when hosted in a Linux environment.

In other words, if you want to pursue a career as a database administrator, for example, mastering the Linux platform is basic.

Cloud computing

With increasingly larger data volumes, companies have been replacing physical spaces with the cloud to store information securely.

As we saw, more than 80% of companies run the Linux system on their servers.

Therefore, if you want to work with Big Data, learning Linux is the way.

Systems Administration

Mastering Linux is the first step for those seeking to work as a systems and networks administrator.

After all, it is also a dominant operating system in this area.

To manage servers, you will have to know the platform like no one else.

Where is it used? 11 examples of companies that use Linux

It is worth repeating that the major companies in the world, from different segments, are using Linux for the most diverse tasks and processes.

Whether for storing large volumes of data, developing mobile solutions, customizing demands, performing more assertive and dynamic maintenance, or optimizing performance, the truth is that the operating system is gaining more and more space.

See examples of companies that use Linux:

1 – NASA

NASA needs great processing power to perform complex calculations, store data securely, and conduct research and experiments.

Yes! NASA uses Linux on its satellites, on its robots, and on its supercomputers.

Almost all supercomputers in the world use Linux. Supercomputers are also used for various things that affect your daily life, practically without you realizing it.

The official number is that almost 94% of the world's 500 largest supercomputers run on Linux.

2 – CERN

The largest and most expensive machine built by man, which attempts to reveal the deepest and most fundamental mysteries of physics, uses Scientific Linux.

The processors at CERN laboratories process more than 15 petabytes per year, the amount of data used to supply the LHC (Large Hadron Collider) in a year. Linux is very efficient in these tasks.

3 – The world's militaries

Specifically in the United States, the world's most advanced fleet of submarines uses Linux to control all onboard systems.

There are also many other US military projects that use Linux, such as drones and aircraft.

4 – The New York Stock Exchange

150 billion in stocks and bonds are traded every day on the most active stock exchange on the planet.

And to your surprise, the New York Stock Exchange states that it uses Linux in all its operations, because any small error could mean a loss of several million dollars.

5 – The world's governments

Various governments around the world are switching their operating systems to Linux, because they cannot spend millions of dollars on licenses for other software. The change of course must be gradual.

In Brazil, it is mainly used for administrative tasks, that is, for servers and user PCs that work in the government.

6 – The Japanese bullet train

It is the most punctual rail system in the world and uses Linux for all its tasks, from organization, time control, to administrative tasks.

Each year, the Shinkansen (bullet train) transports more than 151 million passengers per year, at a maximum speed of 320 km/h.

7 – FAA

It is the Federal Aviation Administration of the USA. They must monitor all air traffic and execute many support and administration tasks for American aviation.

Here, specialists and artificial intelligence systems are required to perform calculations and make decisions that can affect thousands of passengers.

8 – Facebook

Facebook also uses Linux, specifically to operate the data of its more than 1.00 million users, using a modified version of CentOS 5.2.

9 – Google

The choice was simple for Google: the lowest price, the best performance, and the ability to customize any part of the operating system.

Google not only uses Linux on its thousands of high-performance servers, but also on PCs where each employee can customize their Linux as they wish.

10 – Wikipedia

More than one million items that everyone uses for schoolwork are hosted on Linux servers.

Thousands of visitors per minute and fewer than 10 people to manage all maintenance work. Do you think you could do this with Windows?

11 – Android

The Android present in more than half of the cell phones in the world use Linux. Did you know?
