What is KernelCare?

  • 0

KernelCare is a service that provides important updates for your running kernel, eliminating the need to restart your server. KernelCare was developed by CloudLinux and therefore works intrinsically with any CloudLinux-run server, however, KernelCare is able to work with 3rd party drivers. The best part about it: it's all automatic.

KernelCare is devoted to keeping your servers safe and efficient, so with a KernelCare license, you don't have to restart your server every time a new patch or kernel needs to be updated. You can run your servers for years without rebooting! KernelCare takes nanoseconds to update, which means there is little to no impact on your server's resources.
