What is Rocky Linux?
Rocky Linux was developed in 2021 as a direct response to CentOS’s announcement that it would no longer be a binary-compatible, downstream fork of Red Hat Enterprise Linux (RHEL). The goal was to develop an up-to-date and alternative operating system to CentOS.
Since CentOS was a popular distribution, the announcement was criticized widely. One of the creators of centOS, Gregory Kurtzer, was responsible for creating Rocky Linux.
Development and Growth
Since its inception, Rocky Linux has quickly grown to become a widespread Linux distribution. This is mainly because many people in the Linux community consider it an alternative to CentOS.
According to Kurtzer, Rocky Linux continues to witness “massive” adoption, with monthly downloads reaching up to 250,000. What’s more, the distribution is supported by several major companies. This gives users the peace of mind that the distribution will continue to be developed and maintained.
What is CentOS?
The Community Enterprise Operating System (CentOS) was created in 2004 as a free and community-supported rebuild of RHEL. It was designed to be 100% binary compatible with RHEL. This means the software compiled for RHEL would also run on CentOS without any modification.
CentOS quickly became popular and was adopted by many businesses and government agencies. Most of its users were people looking for a robust and secure platform with a reputation for long-term support and stability.
CentOS Stream Shift
In 2020, CentOS announced it would shift its focus to CentOS Stream. CentOS Stream is a rolling release distribution based on the latest development code for RHEL. This shift meant CentOS would no longer follow the traditional model of being a downstream rebuild of RHEL.
The shift led to concerns among users who relied on CentOS for its stable and predictable nature. They thought that the battle of CentOS Stream vs Rocky Linux was unnecessary. Although CentOs Stream may have the latest features because it’s always up-to-date, it’s less stable than RHEL.
Extra Tip: CentOS project oversees two distribution channels: CentOS Stream and CentOS Linux. As users weigh the options between Rocky Linux vs CentOS Stream, consider the implications of the CentOS Stream Shift.
