Customer Demand and Open Source Development

• SUSE follows the “upstream first” principle

• Upstream first exceptions are only considered after analysis of risk, benefit, customer, and market demand

Swap over NFS – support customers on implementing clusters with huge memory demands and match features of typical UNIX systems. Implemented in SUSE Linux Enterprise 11 SP1, meanwhile accepted upstream, with SUSE's help.

High Availability – Outlook 12

SUSE Linux EnterpriseLive Patching

Manage Without Downtime

SUSE® Linux Enterprise Live Patching

Technology “kGraft”

What?• Kernel Live Patching• Designed and developed by SUSE Labs• Ease of use: Builds on well known update processes

Status?• Currently integrated “Upstream” (=Kernel community)

Competitive Advantage?• Works with zero execution interruption

‒ As opposed to competition who stop the whole system (miliseconds to seconds range) when patching

SUSE® Linux Enterprise Live Patching

Kernel Live Patching – Use Cases

• Mission Critical systems‒ Improve general availability‒ Run until the next “maintenance window”

• Help with deployment challenges‒ No need to update all 10000+ systems at one shot, but be able

to run until a specific state is reached• See also:

https://www.suse.com/communities/conversations/need-kgraft-2/

Caveat: Not all issues can be fixed using “kGraft”;in special cases a reboot might be necessary
