5 SUSE & openSUSE – Working Together

Stable code and contributions

Mutual collaboration

Upstream innovations

6 These common elements are core to all openSUSE and SUSE distributions

• YaST

• openSUSE Build Service

• Stability and testing - openQA

7 The openSUSE Distributions

8 openSUSE Tumbleweed • The Tumbleweed distribution is a pure rolling release version of openSUSE containing the latest stable versions of all software instead of relying on rigid periodic release cycles.

• Tumbleweed is based on Factory, openSUSE's main development codebase. Tumbleweed is updated once Factory's bleeding edge software has been integrated, stabilized and tested. Tumbleweed contains the latest stable applications and is ready and reliable for daily use.

• Started in November 2014, install it from a ‘snapshot’

10 Tumbleweed – A Rolling Release...

• No updates, only urgent patches and upgrades

• Tumbleweed snapshots often include hundreds of new package upgrades

• To keep Tumbleweed updated to the latest snapshot, run the following command as root (ideally inside a screen or tmux session):

• zypper dup

11 openSUSE Leap Leap Is The openSUSE Stable Release!

• Aimed at developers, sysadmins, and users

• Defined lifecycle – annual releases

• Direct alignment to SUSE Linux Enterprise Releases

• Server ready!

13 Leap Is The openSUSE Stable Release!

• Leap uses sources from SUSE Linux Enterprise (SLE)

• First release of Leap was November 4, 2015, as openSUSE Leap 42.1

• The latest release of openSUSE Leap, 15.1, was released on May 22, 2019

• Leap 15 has an estimated 36 months of maintenance and security updates

14 Cool Stuff In LEAP!

• Your choice of GUI – KDE Plasma, GNOME, or other

• Linux Containers and Containerized Applications

• Developer and IDE: gcc7, GNOME Builder, Qt5 Configuration Tool, GTK 3.22.30

• Go, Rust, Haskell, C++, Ruby on Rails, Java, Python, Perl, and more

• Transactional server role

• Libvirt virtualization, Pacemaker HA

• translation interface

15 Committed Distro Alignment for the Future…

16 Why SUSE Linux Enterprise?

Zero Downtime Focus Enterprise Support Maintenance / CVEs 10 Year Lifecycle ISV/IHV Certifications Multimodal Modularity

17 Multimodal IT

A co-existence of traditional Multimodal infrastructure, Platform software-defined infrastructure and application oriented architectures.

18 Multimodal Architecture

SUSE Cloud Application Container Workload Platform SUSE Virtual CaaS Workload SLE Platform Machine S SUSE Enterprise Storage Appliance Workload SLE D SLE 15 Products SDI Products Services Traditional Software-Defined Infrastructure Infrastructure (SDI)

Common Code Base All Architectures (x86-64, Arm, POWER, IBM Z)

19 Multimodal OS Requirements

Software-defined Traditional Infrastructure Infrastructure

Multiple use cases Single use case, multiple systems

Manual and automatic installation Automatic and centralized installation

Variety of updates, upgrades, legacy Always up-to-date

Variable packaging and installation Fit one purpose

May become huge in size and Small as possible for size and management management

20 https://packagehub.suse.com/

21 SUSE Package Hub

 Broadening software choices for enterprise users, save to install

 Community built and maintained

 SUSE-approved and built at no extra cost

 Public download and SCC integration

Upstream packages

22 23 LEAP And SLE 15 Relationship

Package Hub is built from LEAP Sources

• Packages are labeled *bp151* -- i.e. Leap 15.1 and SLES 15 SP1

• Package Hub rpm signing keys

• No packaging conflicts with existing SLE supported packages

• Package Hub rpms do not invalidate SLE support commitments

24 Migration – How To…Official Instructions

Reference: https://documentation.suse.com/sles/15-SP1/single-html/SLES-upgrade/index.html#sec-upgrade-online--to-sle

High Level steps for migration process:

Obtain a subscription

Install SUSEConnect and register

Modify Repository Assignments

Zypper Distribution Upgrade

Remove Orphaned Packages

25 Migration Demo

26 SUSE Linux Enterprise Subscription T&Cs Commercial Considerations

• Supported migration path to move from OpenSUSE LEAP 15.1 to SUSE Linux Enterprise Server 15 SP1 is available today

• Interoperability investments support an ecosystem that embraces community and developer use cases

• Enterprise support and IHV/ISV certifications can be added as part of the promote-to-production effort -- with minimal disruption

• SLE to OpenSUSE migration is not supported - once a SLE, always a SLE!
