SUSE Linux Enterprise 197 197

The Operating System Challenge Do you need an Enterprise Operating System? “Linux is free as long as your time is worth nothing.” - Jay Ashford • Buy support and services, not software • Extensive IHV/ISV partner ecosystem • Fully tested software upgrades and updates • Technical support from the developers • Thirteen year support lifecycle 198 1 9

SUSE Linux Enterprise Server is the Platform to Support YOUR IT Transformation... Mode 1 Mode 2 19 9

SUSE Linux Enterprise Server 15 Bridge traditional & Create efficiency with Provide transition software-defined Modular+ architecture to enterprise Linux infrastructure 203

Simplify Multimodal IT • Bridge traditional and software-defined infrastructure • Using common code base • Enable easy migration of workloads • Improve management • Ease the adoption of container technology 204

Efficiency through Modular+ Architecture • Innovate • Improve efficiency without disruption • Maintain stability, security, and proven standards • Easily deploy and transition across on-premise and public cloud 205

Accelerate deployments • Transition from development to production • Use OpenSUSE Leap • Simple transition to SUSE Linux Enterprise • Achieve faster time-to-market 206

SUSE Linux Enterprise 15 – Themes Multimodal – address traditional & containerized infrastructure Provide a common code base for traditional and software defined data center. Unified Installer Install all SUSE Linux Enterprise 15 products starting from a single medium. Modular+ Everything is a module: A stable base, progressive options, flexible delivery. Ease of use – hassle-free use of modules & extensions Easily search, install, and use packages across the SUSE universe. 208 2 0

What's New in SUSE Linux Enterprise 15 217 2 1

What’s New SUSE Linux Enterprise Server 15 • Unified installer • Support for migrating from OpenSUSE Leap 15 • Integrated SDK • RMT replaces SMT • SALT • Python 3 • 389 directory server 218

Significant Changes SUSE Linux Enterprise Server 15 • Kernel 4.12 • Firewalld replaced SUSE Firewall2 • cryptconfig is removed! • Support for floppy disks removed • NGINX is fully supported • Chrony replaces ntpd • OpenJDK 10 219

Migration Scenarios SUSE Linux Enterprise Server 15 • For offline migrations the following is supported: • SUSE Linux Enterprise Server 11 SP4 • SUSE Linux Enterprise Server 12 SP2 • SUSE Linux Enterprise Server 12 SP3 • SUSE Linux Enterprise Server 12 SP4 • openSUSE Leap 15 220

SUSE & openSUSE – Working Together Stable code and contributions Mutual collaboration Upstream innovations 22 1

The New openSUSE Distributions openSUSE Leap openSUSE Tumbleweed • Regular release • Rolling Release • Shared core with SUSE Linux • Continuously Updated & Tested Enterprise • Perfect for Upstream Developers & • Perfect for SysAdmins, Enterprise Power Users Developers and Users 22 2

Long Future Ahead openSUSE Tumbleweed Leap Leap Leap 42.3 42.2 15 Core Core Core 12.3 12.2 15 SLE SLE SLE 12 SP2 12 SP3 15 22 3

For example... A Transactional Update is an update that is: • Atomic. It is either fully applied, or not at all. Also the update is accomplished as a single transaction, that does not influence the running system. • Easily reverted. If an update fails, or if the successful update is deemed to be incompatible or otherwise incorrect, it can be quickly discarded to immediately return the system to its previously functioning state. Developed as part of the Kubic project for use in SUSE CaaSP, transactional- update is available now in openSUSE Leap 15. Also available as a technology preview in SLE 15 SP1. 2 2
