Choosing the best Linux server distro: CentOS, Fedora, and others

Linux distros for server are quite popular among those who manage servers. This article will tell you about the best Linux distributions for servers: features, pros, cons, and more.

You can use almost any server Linux distros to work with a server, but some distributions are specialized and configured in ways that make them much better and easier to work with.

What to look for when choosing a server Linux distros

There are several important criteria to consider when choosing a Linux distribution for servers. Here are some key factors to consider:

  • Stability is critical for server environments. Look for a linux distro for server that offers versions with long-term support (LTS) and regular updates.
  • Most server operations involve the communication of sensitive data that requires strong security measures. Consider distributions that regularly release security patches and enhancements.
  • Ensure the Linux OS you choose supports the hardware you plan to use. Check for compatibility with storage controllers and other required components.
  • Consider the size and activity of the distribution's community. An active community can provide valuable support, documentation, and resources for troubleshooting and optimizing your server installation.
  • If you expect your server to handle heavy traffic or resource-intensive workloads, choose a linux distro for server that is optimized for performance and scalability.
  • Consider the availability of software packages and tools in the distribution's ecosystem. Ensure that the distribution offers a wide range of software options to meet the needs of your server applications.

In addition, good documentation and additional resources can help set up and maintain your server. If you prefer more professional support, look for linux server distro that offer appropriate contracts. These contracts can provide access to timely support, troubleshooting assistance, and additional resources.
