CloudLinux OS is a proprietary Linux distribution specifically designed for shared hosting service providers, created by CloudLinux, Inc. It is derived from the CentOS operating system and employs the OpenVZ kernel along with the rpm package management system.
Overview
The core of CloudLinux OS is a customized kernel built on OpenVZ technology, featuring its primary advancement known as the Lightweight Virtual Environment (LVE). LVE functions by isolating system resources, imposing restrictions on CPU usage, memory allocation, IO operations, IOPS, process counts, among others. Installation is performed via the cldeploy script, which installs the CloudLinux kernel, refreshes yum repositories, and sets up the necessary packages to enable LVE capabilities. Activating the new kernel requires a system reboot. Notably, CloudLinux OS preserves existing packages unchanged, enabling users to revert to the original kernel if necessary.
Creation of AlmaLinux
On February 1, 2021, CloudLinux introduced the initial beta version of AlmaLinux OS, a free operating system intended to substitute CentOS.
By March 30, 2021, with the release of its first stable version, CloudLinux handed over control and development responsibilities to the AlmaLinux OS Foundation. Although CloudLinux pledged an annual funding amounting to $1 million, it no longer retains ownership of the project.
