Discovering the Uncharted Territory: Top Linux Distributions for DevOps in Production ๐Ÿš€ ๐Ÿง


6 min read

Hello DevOps friends ๐Ÿ‘‹, I have experienced similar struggles with managing servers and spent many hours writing code to make sure the deployment works correctly. We all experience this. Being a DevOps engineer with a beard much larger than Santa Claus's ๐ŸŽ…, I have encountered many Linux distributions while working in environments. So, I thought I would tell some experiences from past and give advice to assist you in choosing the correct Linux version for your upcoming work.

Initially, it's important to understand that there is no perfect ๐Ÿ™…โ€โ™€๏ธ solution. The most suitable Linux distribution varies according to the particular requirements and nature of your project. Do not worry, we will look at some well-known options to assist you in making this important choice ๐Ÿง.

The Usual Suspects: RHEL, Ubuntu, and CentOS

These three are experienced veterans in the enterprise Linux field ๐Ÿ’ช. They all have strong stability, good support, and large communities supporting them. Here's a quick rundown:

  • Red Hat Enterprise Linux is considered the top choice for stability and professional support, similar to how one views Lexus as a high-quality brand among car distributions ๐Ÿš™. It is very sturdy, yet it has a high cost ๐Ÿ’ฐ. You should consider using RHEL for long-lasting, large-scale business projects.
# Installing httpd on RHEL using yum
sudo yum install httpd
  • Ubuntu is known as "Linux for Humans" distribution. It's very easy to use, comes with a huge selection of software packages ๐Ÿ“ฆ and it's great for setting up development environments. Consider it like the Honda Civic among Linux versions; very suitable for daily tasks, but perhaps not perfect ๐Ÿ™…โ€โ™€๏ธ for highly crucial production environments.
# Installing httpd on Ubuntu using apt
sudo apt install apache2
  • CentOS, which is free and created by the community, was like a non-commercial version of RHEL. Unfortunately, CentOS is close to its end-of-life phase (RIP ๐Ÿ˜ข). However, there is a similar successor named Rocky Linux which merits attention.

The Underdogs: Fedora and Debian

These two names might not come to mind first for use in production, but you should not overlook them ๐Ÿ‘€.

  • Fedora is like the cutting-edge experimental field for Red Hat, receiving new and advanced packages before others ๐Ÿš€ which makes it an excellent option for doing tests and developing. Consider it similar to the Tesla among Linux distributions; very quick and with the latest features, though sometimes it might lack stability.

  • Debian is the ancestor of many other distributions, such as Ubuntu. It is famous for its steady performance and very reliable package management system. Consider it similar to the Toyota Camry in the world of Linux distributions - trustworthy and consistent, though not necessarily the most eye-catching โœจ.

Wild Cards: OpenSUSE and Arch Linux

These are for the adventurous DevOps warriors out there.

  • OpenSUSE: This distro is made in Germany and it has a reputation for being easy to use, with emphasis on the desktop ๐Ÿ’ป. If you are looking for something very strong but also very friendly experience of Linux, then this could be like Volkswagen among other distros. Reliable and customizable, with a focus on the user experience.

  • Arch Linux: The DIY dream ๐Ÿ› ๏ธ. Arch is for people who like to get their hands dirty and construct their system from scratch. It's not easy, but the amount of customization you can do on it is incomparable ๐Ÿ’ช. Picture it like the motorcycle of Linux distros ๐Ÿ๏ธ. Strong and speedy, but needs much hand setting-up.

Choosing Your Weapon: Factors to Consider

Okay, we get it. Here are some actual things that you can consider when choosing your distro ๐Ÿค”:

  • Stability: How much do you need your application to be available at all times? If it is extremely crucial, then choose a very stable distro such as RHEL or Debian.

  • Package Management: How simple is it to find and install the software you require? Repositories like yum (RHEL) and apt (Ubuntu/Debian), they assist a little ๐Ÿ“ฆ.

  • Support: Do you require commercial support or is a strong community enough? RHEL provides paid assistance, whereas other options depend on community forums and online help ๐Ÿค.

  • Release Cycle: How frequently would you like updates? Some distros have rapid ๐Ÿ”ฅ release cycles (e.g., Fedora), whereas others maintain a slow ๐Ÿข but constant pace (e.g., Debian).

  • Security: The need for high-level security ๐Ÿ” is crucial. Some distros have a strong focus on providing frequent security updates and patches.

It's Not Just About the Distro: Containerization

Docker, Docker and still Docker! At present time, containerization is the key game changer ๐Ÿ‹. When you containerize your applications it becomes quite distro-agnostic. Let me explain why this matters:

  • Consistency: Your application is in its own container, so it operates consistently no matter the distro underneath ๐Ÿ“ฆ.

  • Portability: Containers make deployments across environments like development, testing, and production a breeze ๐Ÿ’จ.

Real-Life Examples: When to Use Which

Let's get practical. Here are some scenarios and what distros might fit the bill:

  • Hyper-critical Banking Application: When it comes to stability, RHEL is the most likely choice for you, as it has strong commercial backing ๐Ÿฆ.

  • Web Development Environment: Be flexible and use the newest tools. Ubuntu or Fedora are good selections ๐Ÿ’ป.

  • Large-Scale Data Science Project: For a big data science project, stability and good support for the package ecosystem of data science libraries are crucial factors. Debian or CentOS/Rocky Linux could be good choices ๐Ÿ“Š.

  • Bleeding-Edge Tech Startup: If you are ready for the newest features and can handle a bit of instability, then Fedora or Arch Linux might be your playground ๐Ÿš€.

Beyond the Distros: The Importance of DevOps Tooling

Don't forget, the distro is just a single part. The real DevOps magic starts when you use the correct tooling โœจ:

  • Configuration Management: Automation of infrastructure management is possible with tools such as Ansible, Puppet or Chef โš™๏ธ. The time of manually setting up servers is over!

  • Continuous Integration/Continuous Deployment (CI/CD): Jenkins, GitLab CI and similar tools assist in making your delivery pipeline more efficient ๐Ÿ’ซ. This permits you to present updates often and reduces the time it takes for products to reach the market.

  • Monitoring and Logging: Nagios, Zabbix, ELK (Elasticsearch, Logstash, Kibana) stack let you monitor your systems and catch problems before they become serious troubles ๐Ÿ”Ž.

Parting Thoughts

DevOps in production does not have one "best" Linux distro. It relies on your needs and how much risk you can handle โš–๏ธ. The important thing is to try out different options, know what you require, and utilize the great tools that form the DevOps world. Lastly, recall that DevOps is an ongoing process of enhancement. Reconsider your tech stack when your projects (and beard) flourish!
