Why do top software companies choose Rocky Linux as their primary supported OS?

For the visual effects industry, Rocky Linux is preferred because it’s compatible with major VFX software like DaVinci Resolve, which runs well on RHEL-based systems. The stability and performance of Rocky Linux fit well in multi-user environments typical in Hollywood studios. There's even a standard for VFX platforms that many studios adhere to, making it a go-to choice for those specific applications.

Rocky Linux is essentially a free alternative to Red Hat Enterprise Linux (RHEL), making it popular for enterprises looking to avoid the high subscription costs. It's stable and doesn't change interfaces frequently, which means updates won’t break compatibility with their software as long as they stick to RHEL specs. This stability is crucial for long-term projects, especially in enterprise settings.

A big reason behind companies choosing Rocky over Alma Linux could be how they market themselves. Rocky claims to be closely aligned with RHEL, and many companies who used CentOS before its transition found moving to Rocky more straightforward. Some users appreciate that it carries less political baggage than some of its competitors, which might reassure those looking for a more straightforward path post-CentOS.

It seems Rocky appeals to many because it allows for long-term support of software with minimal intervention. You can publish software to be compatible with Rocky and expect it to work for years, which is a huge benefit in reducing the support workload for development teams.

I've noticed that while Rocky Linux is gaining traction, Ubuntu is still the leading choice for many applications I've come across. Ubuntu LTS versions are popular because they offer long-term support—5 years of regular support and up to 10 years of security updates. This makes it easier for developers to ensure their software remains stable for many years without constant updates. Plus, it’s user-friendly, particularly for server setups. That said, Rocky Linux provides a solid option particularly for enterprise environments that need RHEL compatibility without the hefty support costs.
