OS add-on enables Linux kernel patching without rebooting.
SoftLayer Technologies, an on-demand data center services provider, today announced that it has added Ksplice Uptrack to its wide range of available services. The Linux operating system (OS) add-on enables kernel security updates to be installed on SoftLayer Dedicated Servers or CloudLayer Computing instances in seconds, while systems are running with no reboot required.
The company explains that Ksplice Uptrack collects Linux updates from all major vendors, converts each into a rebootless update, and then publishes the updates to Ksplice Uptrack servers for seamless download and installation. Ksplice operates at the object code layer, enabling it to transform many traditional source code patches into hot updates with little or no programmer involvement. Key features include:
Virtualization support for VMware, Parallels Virtuozzo, Citrix Xen, and more
Compatibility with control panels and third-party kernel modules
Rollback capability to instantly reverse any update
Performance neutrality, not requiring a persistently running process
Convenient browser-based tool for seeing if systems are up to date
It adds that Ksplice Uptrack servers are on the company private network, streamlining installation for its customers and using no metered bandwidth for installation. Ksplice Uptrack can be ordered today for new servers at www.softlayer.com or for existing servers through the SoftLayer Customer Portal (http://www.softlayer.com/manage).
"We're excited to offer customers the advantages that Ksplice provides for managing their Linux systems," said Nathan Day, Chief Scientist for SoftLayer. "Now, there is no need to delay updates to maximize uptime on your production environments. You don't even have to reboot to set Ksplice up the first time."
