1 SUSE Linux Enterprise Roadmap Maris Smilga

2 SUSE in the Enterprise Years Linux 70% SAP on Linux 80% Linux on IBM System z

3 7 Reasons to choose SUSE Linux Enterprise 1. Connecting and Balancing Communities 2. Open source community contribution 3. Service quality 4. Technology leadership 5. Sustainability and predictability 6. Interoperability 7. Ready for future and growth 3

4 1. Connecting and Balancing Communities

5 Connecting and Balancing Communities IHVs ISVs Community Customers 5

6 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 Example: 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. 6

7 2. Open Source Community Contribution

60 Towards Zero Downtime System Rollback - Future SUSE Linux Enterprise 12: Extended system integration Support for Service Pack rollback Support for Kernel Upgrade Full system rollback 73

61 High Availability Increase Service Availability 74

62 Towards Zero Downtime High Availability Status Fighting Murphy's Law Service failover at any distance from local to geo Up to % availability Rolling updates for less planned downtime Easy setup, administration, management Virtualization agnostic Leading open source High Availability On par with proprietary products Secure the business! 75

63 Towards Zero Downtime High Availability Benefits Quickly and easily install, configure and manage clustered Linux servers Increase service availability for mission-critical systems and data Transparent to Virtualization nodes can be virtual or physical or mixed! Integrated with SUSE Linux Enterprise Server Meet Service Level Agreements 76

64 Towards Zero Downtime High Availability Outlook 12 Keep it most up-to-date Storage Usability SCSI reservation handling, GFS2, drbd (data replication) HAWK (web console), crm shell, wizards & templates Extend GEO framework to a full solution stack GEO reference architecture IP take-over (via dynamic DNS) Multi-tenancy arbitrator (for multi-cluster environments) 77

65 SUSE Linux Enterprise Live Patching Manage Without Downtime 78

66 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 79 As opposed to competition who stop the whole system (miliseconds to seconds range) when patching

67 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 systems at one shot, but be able to run until a specific state is reached See also: Caveat: Not all issues can be fixed using kgraft ; in special cases a reboot might be necessary 80
