<p>CloudLinux OS provides a modified kernel based on the OpenVZ kernel. The main feature is the Lightweight Virtual Environment (LVE) – a separate environment with its own CPU, memory, IO, IOPS, number of processes and other limits.<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> Switching to CloudLinux OS is performed by a provided <code>cldeploy</code> script which installs its kernel, switches yum repositories and installs basic packages to allow LVE to work. After installation the server requires rebooting to load the newly installed kernel. CloudLinux OS doesn’t modify existing packages, so it is possible to boot the previous kernel in the regular way.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup>

<p>CloudLinux released the first beta for <a href="AlmaLinux" title="AlmaLinux">AlmaLinux OS</a>, a free operating system intended as a substitute for CentOS, on February 1, 2021.
</p><p>On March 30, 2021, the same day as the first stable release, CloudLinux transferred the responsibility for development and governance of the project to the AlmaLinux OS Foundation. CloudLinux has promised $1 million in annual funding to the project, but does not own the project anymore.<sup id="cite_ref-8" class="reference"><a href="#cite_note-8"><span class="cite-bracket">[</span>8<span class="cite-bracket">]</span></a></sup>
