The KernelCare Linux kernel patching service is a system offered by CloudLinux. This product provides ongoing security patches for many Linux kernel versions. Updates are installed live without requiring a system reboot, which is a tremendous incentive when running an active server. Because CloudLinux offers a free symlink (symbolic link) protection patch for servers running CentOS 6 and 7, Liquid Web is replacing existing versions of KernelCare with this free version.
Liquid Web was recently informed that the licensing cost for CloudLinux will be increasing at the beginning of the new year and will take effect on January 1st, 2021. All CloudLinux license types (both standalone and those bundled with cPanel) will increase by $2.00 per month with no variance on license type.
