LinuxCon+ContainerCon Europe 2016

Minimizing downtime is at the heart of every IT manager because end users are more satisfied if their work isn't blocked by an system outage. However, downtime is unaviodable if a mandatory system updates must be applied in order to fix a critical security hole. But what if there is a technology that can solve this paradox by updating the system without downtime? The upstream project "livepatch", fed with the best from the distributor specific implementations kGraft from SUSE and kpatch from Red Hat, is about to make that happen for the Linux Kernel itself - the core component of every system, where patching would always require a reboot. In this presentation, Hannes Kühnemund will talk about recent developments, discuss the current state including a deep dive into challenges on the way.
