Are you trying to decide on a Linux server distro (distribution)? This article will help guide you based on the strengths of the Linux server distributions available. If you are looking for desktop advice, have a look at Choosing the Best Linux Distro for Desktop.
Best Linux Server distro
Again, the first rule to remember is that there’s really no single “best” Linux server distro. Instead, there’s a best suited Linux server OS based on “your” preferences and requirements. With that in mind, lets begin by breaking down the search for your best Linux server distro into 3 categories: 1) General, 2) Enterprise based/sponsored and 3) Commercial Enterprise Linux.
