SUSE Linux Enterprise Live Patching

Live Patching is a cutting edge technology that improves business continuity and saves costs by reducing downtimes, increasing service availability and enhancing security and compliance. Using Live Patching, you can apply patches to your Linux kernel without rebooting your system. Your applications keep running while you patch the Linux kernel for critical updates.

With Live Patching for IBM Power and Live Patching for x86 you can maximize uptime for a wide range of systems and applications.

Live Patching is independent of the application running on the Linux kernel. So you can keep running any of your business-critical applications ranging from enterprise Artificial Intelligence apps, big data analytics, databases (Oracle, SQL, etc.) to performance demanding in-memory database applications such as SAP HANA.

Reduce Downtimes

For both planned or unplanned downtimes by patching your systems when you need to.

Keep Your Business up and Running

With increased service availability by enabling your business-critical services to run without interruption.

Enhance Security & Compliance

By ensuring systems stay up-to-date with security patches and the capability to audit applied patches.

An example scenario: Here is a snapshot of a Linux kernel over 10 months as new security vulnerabilities (Common Vulnerability Exposures—CVEs) keep coming.

As a system administrator, you could be spending several man days each month applying patches, synchronizing the patches across all your systems and rebooting the systems. As each month goes by the unpatched CVEs continue to increase the security exposure.

You can avoid this scenario and stay secure by Live Patching the kernel each month when critical updates become available without interrupting your running applications.

Use Case: Virtualization Environment Running Oracle Database

SVHW uses Live Patching to maintain continuous uptime for its virtualization layer.

“Without Live Patching, we would be faced with bringing down all 40+ virtual machines each time we needed to apply critical patches—at least once a month.”

SVHW saves 2 days per month (24 days per year) in administration time managing & applying patches.
