This document discusses DevOps and SUSE's solutions to enable DevOps. It provides an overview of key components for DevOps success like good habits, lean development, and automating everything. It then describes how SUSE solutions like Open Build Service, KIWI, Jenkins, and SUSE Manager can help plan, build, test, release, operate and monitor applications. The document also discusses SUSE's approach to containers and orchestration with MicroOS, Kubernetes, and SUSE CaaS Platform.

The SUSE Approach
SUSE design principles:
• Open source and open
development
• APIs
• Standards based (protocols,
languages, etc.)
• Enterprise focus

7. 8
SUSE Components– Open Build Service
• Supports all major Linux distributions and
software packaging formats (rpm, deb,
containers, installation media, images)
• Support multiple architectures (i586,
x86_64, aarch64, ppc64, ppc64le, s390x)
• Web client and a CLI (osc)
• Allows for simple package creation
• Add external software repositories
• Build packages locally or on source server
• Collaboration via
branching/merging/review/commit -
request tracking

8. 9
Open Build Service (OBS)

video
https://en.opensuse.org/openSUSE:OpenQA

15. 17
• Yearly Release
• Deliver new compiler and toolchain

Containers module
Enterprise Ready
• Pre-build and signed images from a trusted source
• Full control over your data: On-premise registry, authentication
• Application Runtime for SUSE Linux Enterprise 11 and 12
Integration and management of Containers
• Integration with SUSE Manager and SUSE OpenStack Cloud

What is SUSE Linux Enterprise MicroOS
SLE MicroOS is a modern Linux
Operating System, designed for
containers and optimized for large
deployments.
MicroOS inherits the SLE knowledge
while redefining the operating system
into a small, efficient and reliable
distribution.

What problems are we trying to solve with
MicroOS?
A small and easy to manage/upgrade OS
Organizations using containers need
Ability to quickly setup/manage a cluster of nodes
Always up-to-date Operating System
Transactional updates

SUSE Linux Enterprise 12 for Raspberry Pi
• 64-bit SUSE Linux Enterprise Server 12 distribution for the Raspberry
Pi 3 Model B (Will not work on earlier, 32-bit Raspberry Pi models)
• Packaged as an image that is ready to copy to an SD Card
• Includes compilers and development tools
• Comes with a free one-year, self-service subscription
• Enabled for Wi-Fi, Bluetooth, HDMI, Ethernet, and GPIO
• Download from https://tinyurl.com/slespi
• Q&A support on https://forums.suse.com/forum.php

40. 42
SUSE Linux Enterprise for Raspberry Pi
Differences Compared to Raspbian
Based on Upstream Kernel
While Raspbian uses a kernel with modifications especially for the Raspberry Pi, SUSE Linux
Enterprise Server for the Raspberry Pi uses the SUSE Linux Enterprise kernel for AArch64.
64-bit ARM AArch64 Instruction Set
SUSE Linux Enterprise Server for the Raspberry Pi is the first commercial distribution for the
Raspberry Pi using the ARM 64-bit AArch64 instruction set.
Boot Process
In Raspbian, the kernel is loaded directly. This is not supported by SUSE Linux Enterprise Server
for the Raspberry Pi, where the U-Boot boot loader is used to provide an EFI boot environment. A
GRUB2 EFI binary is chain loaded to provide a graphical boot screen.
Root Filesystem
SUSE Linux Enterprise Server for the Raspberry Pi uses btrfs as the file system for the root
partition. Compression is enabled by default for better SD-Card performance.
