Linux: Press Release

Now, Update Linux Servers with No Downtime

KernelCare automatically updates Linux servers with no need to re-boot, no need to delay applying security patches

With KernelCare, now available from CloudLinux, scheduled outages for security patches on Linux servers are now a thing of the past, giving organizations real-time updates.

KernelCare automatically applies Linux server security updates without having to re-boot, freeing technical personnel from the laborious process that takes several minutes for every server, several times a year.

"This is the equivalent of changing the engine on an airplane while it's flying," said Dan Olds, principal analyst, Gabriel Consulting Group. "I think this will be viewed as a no brainer purchase when you consider the cost of less than $50 annually per server for having the protection of kernel security updates without downtime."

"In our experience, KernelCare has worked perfectly and we love it because we no longer have to suffer through performance issues related to re-booting servers," said Wouter de Vries, founder and CEO of Antagonist, a web hosting provider in the Netherlands (www.antagonist.nl). "Plus, now we don't have to wait to find a window of opportunity to apply security updates because those are done automatically as soon as they're available."

KernelCare loads patches using one module for greatest efficiency with no impact on performance since those take only nanoseconds. For container virtualization, like OpenVZ, there is only one Linux kernel to update no matter how many virtual servers are running on the physical host. If there are 100 virtual servers running on one physical host, each would have needed to be stopped and restarted. With KernelCare, patches are done automatically as soon as they become available, while the machine continues to run - no delay, no downtime.

"Today, system administrators have to re-boot a server to apply the latest kernel security updates, which come out every one to two months," said Igor Seletskiy, founder and CEO, CloudLinux. "However, because they require a scheduled update (to minimize disruptions from downtime), they are often delayed - sometimes months or even years - which means the server is running with known security vulnerabilities. The problem of having to schedule downtime and then update and re-boot servers in a short period of time is a strain on resources for enterprises of every size. KernelCare solves this update and re-boot issue by providing live kernel patching without the need for the re-boot."

Availability and Pricing

KernelCare is available via monthly subscription of $3.95 per server, ordering instructions can be found at http://kernelcare.com/pricing.php. The kernel module is released under GPL2 while other components are distributed in binary-only format under license. KernelCare has been available in limited availability to web hosting providers for the past month and is already installed on more than 500 servers. KernelCare is now available for CentOS 6, Red Hat Enterprise Linux (RHEL) 6, CloudLinux OS 6 and OpenVZ (64-bit only). CloudLinux plans to add support for Debian and Ubuntu, as well as CentOS 5, RHEL 5, CloudLinux OS 5 within the next 60 days. In addition, RHEL 7 will be supported once it is out of beta.

The excitement around the possibilities enabled by Big Data is being tempered by the daunting task of feeding the analytics engines with high quality data on a continuous basis. As the once distinct fields of data integration and data management increasingly converge, cloud-based data solutions providers have emerged that can buffer your organization from the complexities of this continuous data cleansing and management so that you’re free to focus on the end goal: actionable insight.
The Internet of Things (IoT) is causing data centers to become radically decentralized and atomized within a new paradigm known as “fog computing.” To support IoT applications, such as connected cars and smart grids, data centers' core functions will be decentralized out to the network's edges and endpoints (aka “fogs”). As this trend takes hold, Big Data analytics platforms will focus on high-volume log analysis (aka “logs”) and rely heavily on cognitive-computing algorithms (aka “cogs”) to mak...
With several hundred implementations of IoT-enabled solutions in the past 12 months alone, this session will focus on experience over the art of the possible.

With the ability to support a billion sensor events per second, over 30PB of warm data for analytics, and hundreds of PBs for an data analytics arc...
Cryptography has become one of the most underappreciated, misunderstood components of technology. It’s too easy for salespeople to dismiss concerns with three letters that nobody wants to question. ‘Yes, of course, we use AES.’ But what exactly are you trusting to be the ultimate guardian of your data? Let’s face it – you probably don’t know. An organic, grass-fed Kobe steak is a far cry from a Big Mac, but they’re both beef, right? Not exactly. Crypto is the same way. The US government require...
