The Red Hat family is a pipeline, and a name's position in it tells you whether to put it under a production website. Fedora 1,480 is the front. Fedora 44 arrived on 28 April 2026 and is supported to 2 June 2027: a release lives until four weeks after the release two cycles later, about thirteen months, so a server on it needs a full upgrade every year. CentOS 2,757 Stream 10 sits between Fedora and RHEL 664 , carrying the changes headed for the next RHEL minor release: a preview, not a rebuild. Do not confuse it with CentOS Linux, the free rebuild hosting companies once ran. It is gone: version 8 ended on 31 December 2021 and version 7's security support on 30 June 2024.
Red Hat Enterprise Linux 10 shipped on 20 May 2025, with full support to 31 May 2030 and paid extended life support to 2039. You pay for a decade of stability and someone to call.
Rocky Linux 10 11,029 (11 June 2025) and AlmaLinux 10 7,122 (27 May 2025) fill the hole CentOS left: free, tracking RHEL 10's dates, with security support to 31 May 2035. Rocky aims at bug-for-bug equivalence with RHEL; since July 2023 AlmaLinux targets ABI compatibility instead, which lets it ship fixes ahead of upstream. For a PHP application they are interchangeable.
