KernelCare by CloudLinux Reaches 20,000 Server Installs Milestone

Arcadia, CA (PRESS RELEASE) March 11, 2015 KernelCare (, a service that makes rebootless kernel updates possible by leading advanced Linux operating system (OS) developer CloudLinux (, announced today it has reached 20,000 server installs. KernelCare is used by hosters and Enterprise customers looking to improve security and add efficiency to day-to-day maintenance of their servers.

While KernelCare improves security, the service also helps hosters and Enterprise customers save money as system administrators no longer need to spend time and resources managing kernel updates. As a result, server uptime improves, eliminating customer impact and lowering the churn rate.  

We developed KernelCare so kernel updates and patching can be done without reboots, which often incurs a significant amount of downtime, planning, and additional resources in terms of time and human intervention, says Igor Seletskiy, Founder and CEO at CloudLinux. There is absolutely no impact on performance as KernelCare loads patches and offers the ability to roll back changes.

New security vulnerabilities are regularly found in the kernel, leaving system administrators scrambling to find updates, which often results in planned downtime and additional work associated with updating the kernel. Work has to be done during off hours as part of scheduled maintenance, leaving servers vulnerable to the latest security threats.

With KernelCare there is no downtime and no planning as everything is done automatically without service interruption and without intervention from system administrators, says Seletskiy. There is no advanced planning required with KernelCare. Essentially, system administrators can install KernelCare and let the system handle everything moving forward.

At 20,000 server installs in less than a year after launch, KernelCare is helping leading data centers and hosting companies update their kernels, saving time and keeping servers online without any reboots. KernelCare takes only minutes to deploy and is an inexpensive option hosters can use to keep their servers running properly.

KernelCare gives us peace of mind knowing our kernel is patched with the latest security fixes while avoiding downtime from constant reboots, says Bryan Muthig, CEO and Co-Founder at A2 Hosting. The deployment of KernelCare was easy, straightforward, and we have had no issues whatsoever with running KernelCare on our servers. We highly recommend KernelCare to anyone who wants a rebootless kernel environment KernelCare is the answer.

In addition to rebootless kernel updates, KernelCare will be releasing an open source patch generation component along with a KernelCare portal designed exclusively for Enterprise, and will be offering greater support for larger hosters in the coming months. Additional distributions, distribution versions, and kernel support are coming as KernelCare continues to evolve and build its customer base.

Previously it took days to plan and install kernel updates, costing companies time and money, says Seletskiy. We will continue to innovate and develop KernelCare as we have done with the CloudLinux OS so our customers can improve their services, save money, and enhance their offerings.

KernelCare supports CentOS, Debian, Virtuozzo, OpenVZ, RedHat, Ubuntu, and CloudLinux.
