As part of a massive migration campaign, LinkedIn has successfully moved their operations to Microsoft’s Azure Linux as of April 2024, ditching CentOS 7 in the process and taking advantage of a more modern compute platform.
As many of you might already know, back on June 30, 2024, CentOS 7 reached the end-of-life status, resulting in no new future updates for it, including fixes for critical security vulnerabilities.
…
The developers have gone with the high-performing XFS filesystem, which was made to work with Azure Linux to fit LinkedIn’s use case. In their testing, they found that XFS was performing well for most of their applications, except Hadoop, which is used for their analytics workloads.
When they compared the issues that cropped up, XFS came out as a more stable and reliable choice than the other candidate, Ext4.

Additionally, LinkedIn’s MaaS (Metal-as-a-Service) team has developed a new Azure Linux Image Customizer tool for automating image generation, that takes an existing generic Azure Linux image, and modifies it to use with a given scenario. In this case, a tailored image for LinkedIn.

Wow are people dumb. We specifically chose the non-IBM source for continuing updates, so that’s two counterexamples to whatever this chucklenuts is pushing.
But - speaking as someone who’s used RHL since 98 and rhel since 3, el8 is so sketchy and el9 is just not worth it. I’ll do Rocky if I have to do anything, as at least it uses the better packaging - albeit requiring to mimic RH’s use in the dumbest way to date with a version-switching that pretends the method they fucking invented for doing that better doesn’t exist, the same as PCLinuxOS that does it better every day also doesn’t exist.
I just hope PCLinuxOS can get a good oVirt/pve template packered before it loses its opportunity to show off how insanely great it is.
