Updates and Release Cycleīoth operating systems focus on stability and only incorporate tested and production-ready features. Since the last version ( v9.0 for both OSes at the time this article was written), they support x86_64, aarch64, ppc64le, and s390x architectures.ĪlmaLinux introduced the s390x support with the latest version, while it added support for aarch64 in v8.4.Ĭontrary to AlmaLinux, Rocky Linux supported aarch64 since the beginning but did not have ppc64le and s390x support until version 9.0. Based on (Architecture)ĪlmaLinux and Rocky Linux are based on RHEL source code, making them both 1:1 bug-for-bug binary compatible RHEL forks.

The sections below explain each OS' features and differences in detail. Rocky Linux comes with the Network Time Security protocol for NTP and Secure Boot support. AlmaLinux comes with CIS Benchmark, allowing users to configure their system security and obtain a full report on potential security issues. The main differences lie in the project funding, which is based on different sponsors, and security. Since both operating systems are built from RHEL source code to fill the gap left by CentOS, there aren't many differences in compatibility, supported architecture, or purpose.

$1M in annual sponsorship from CloudLinux Inc and support from other sponsors. $26M secured for funding the project by CIQ, the founding sponsor and services partner. Regular updates with a lag of up to one business day.
