Liquid Web rolls out KernelCare rebootless security updates to 20K managed servers

Rebootless kernel security update service empowers Liquid Web to keep kernels secure and servers running for their managed hosting customers

Arcadia, CA, May 18, 2016 – Leading OS developer CloudLinux announced today that Liquid Web, a worldwide leader in managed web hosting, has partnered with the company to deploy its service, KernelCare, on 20,000 of its managed servers. This continues the trend of the service's adoption in data centers as it allows for the application of security patches without reboots, which can interrupt critical server functions.

Liquid Web currently represents the largest deployment of KernelCare in the managed hosting space in terms of licenses. Launched 2 years ago, KernelCare keeps Linux servers secure with all of the latest kernel patches, automatically, applied to the running kernel without downtime.

“We are committed to delivering the best solutions for our customers and, with that, we have come to consider KernelCare as an essential service”, said Joe Oesterling, Chief Technology Officer at Liquid Web. “As the Industry adopts KernelCare, it should eventually eliminate the concern of rebooting servers to apply security patches in most instances.  The downtime that reboots cause is a disruption for customers, and nuisance for admins, that can be easily avoided with KernelCare. We’re moving closer to a time in which this type of disruption is no longer excusable.”

“Liquid Web has a reputation for maintaining the best performing Linux servers, and their roll out of KernelCare only attests to their commitment to delivering most highly available servers,” said Igor Seletskiy, Founder and CEO at CloudLinux. “KernelCare delivers a super-fast release of security patches for new vulnerabilities and we are very excited to be able to not only serve our part in maintaining updated kernels for Liquid Web, but also do it in a seamless way without disrupting customer’s websites and applications.”

KernelCare delivers virtually no performance impact during updates. It supports most popular Linux distributions including CentOS/RHEL/CloudLinux 5, 6 and 7, Xen4CentOS, OpenVZ & Virtuozzo, Debian 6, 7 and 8, Ubuntu 14.04 LTS and 16.04 LTS, and Proxmox VE 3.x & 4.x.
