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.

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

80

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
