IImmutable OS … a topic SUSE is looking into
Is predictable – Is not altered during runtime – Will run the same artifacts consistently on
every boot
instances during runtime – Can be rolled out easily repeatedly with
predictable outcome

OopenSUSE – Closing the Leap Gap Bring more closely together
developer communities, by focusing on openSUSE Leap as a development platform for communities and industry partners;
user communities, by leveraging the benefits of both a stable Enterprise code base and the speed of community contributions;
the code bases of openSUSE Leap and SUSE Linux Enterprise,
by not only sharing sources, but also offering the SUSE Linux Enterprise binaries for inclusion in openSUSE Leap.
Three Step Approach 1. Merge the code bases
for the intersection of openSUSE Leap 15.2 and SUSE Linux Enterprise 15 SP2 as much as possible without loss of functionality or stability.
2. Create a flavor leveraging SLE binaries in parallel to classic openSUSE Leap 15.2
3. Build openSUSE Leap 15.3 with SLE binaries included by default (assuming community agreement)
16
Collection of supplemental open source software for SUSE Linux Enterprise
Built and maintained by the community, approved by SUSE
→ Broaden the package choices for enterprise users
Partner Hub “App Store“ like approach Simplify installation of third
party software on SUSE Linux Enterprise
Integration into SUSE Systems Management Stack
Ease of use – Software from Open source and ISV Communities

QQuality OpenQA
Automated test infrastructure openSUSE and SUSE Ability to test various code
paths / installation options Basic concepts: “jobs,”
“needles,” (png + json) Output: log files, pictures, video
Benefits Fully open source Cross architecture Matches the needs of SUSE
and the openSUSE community in full-product testing
Use also by other communities
Repository Mirror Fully disconnected work Staging support Registration Proxy Reporting & Management
Benefits Maintain Security compliance for
package mirroring
– Even works in highly secure environments physically disconnected from the Internet (needs two RMTs)
Save Bandwidth Fast access to updates Prepared for upgrade to SUSE
Manager for enhanced management capabilities
RMT

Make “best practices” available to all customers
Scalable / Extensible Change the experience of
“installation” to a quasi- imaging model without losing flexibility

updates Recoverable
Transparent Continue to run workloads
while updating your system(s)
→ Trust → more frequent updates
Better automation
UUnified Installer One for all
The Unified Installer install all SUSE Linux Enterprise 15 products from a single medium
One small The Unified Installer medium is
small. It allow easier handling, remote use, and faster refresh cycle.
Beyond SUSE Linux Enterprise SUSE Manager included
Benefits Simplify the access to SUSE
Linux Enterprise and SUSE Manager also on premises
Show the benefits of a Common Code Base in real life: integration, compatility
Good Day 1 administrator experience
Platform for more integration going forward

Migration from SLES to SLES for SAP Applications is supported
SLES 12 SP5 is the last release in SLES 12 codestream
Keep architecture
based on Snapshot/Rollback technology

WWSL – Windows Subsystem for Linux How we provide SUSE Linux Enterprise for WSL
No Windows system required for building SUSE on WSL; we use OBS
WSL can be built fully automated and reproducible
Automated QA included The rpm packages are exactly
identical to the native SUSE Linux Enterprise
Benefits Provides a Container / VM with
a Linux Userland Predefined applications /
containers could be delivered Great to start some Linux
applications quickly when running Windows
Easy to migrate to a native Linux system

YYet ... YaST? YOMI! Yet One More Installer
New type of installer – Parallel, unattended – Simple (YAML) and smart (Jinja2)
configuration files – Easy to orchestrate
(single decision point)
– openSUSE Kubic with kubic-control – SUSE Manager (Work in progress)
Benefits Unattended installation on a
cluster with different profiles – Roles like: control plane, storage,
computation (OpenStack, k8s) – Certain nodes needs to wait until other
nodes are installed
Integration with Salt – DevOps oriented (Git, CMS, …) – Easy to integrate and extend
Ready to scale
