A Tour of Open Source on the Mainframe

Presented by: Elizabeth Joseph, IBM Presented at All Things Open 2020 Abstract: Many enterprises and, as many of us learned during the COVID-19 outbreak, governments, rely on mainframes to do the bulk of their data-driven work and the modern mainframe is very good at what it does. But what if you’re looking to modernize your platform and bring in the DevOps methodologies, tooling, and practice into your organization? Today, there is an entire product line of mainframes that exclusively run Linux (RHEL, SLES, or Ubuntu). With Linux, you get access to the vast ecosystem of open source software that’s already been ported to the mainframe architecture (s390x), with more being ported every month. If your organization is using z/OS, the Open Mainframe Project has a series of open source projects targeted specifically at the mainframe and improving usability. Zowe, for instance, helps create a consolidated API for accessing resources and workload on your system and Feilong is a z/VM connector that allows you to manage your virtual machines with familiar open source tooling like OpenStack. There are even connectors for Jenkins that allow you to integrate CI/CD pipelines with your workloads. In this talk I’ll explore all of this in more to show you how an automated, modern environment can thrive on today’s mainframe.

- 2. $ whoami Elizabeth K. Joseph, @pleia2 I did on-prem things, then cloud things, now I do mainframe things… which are also on-prem and cloud things! ● Author: Official Ubuntu Book & Common OpenStack Deployments ● Linux Systems Administrator ● Developer Advocate for IBM Z 2
- 3. What is a mainframe? 3
- 4. What is a mainframe? 4
- 5. What is a mainframe? 5 Not x86. (it's s390x!) 190 5.2ghz processor units (PUs), with 12 cores per chip But also... • 40TB of RAM • 60 PCIe control units across 12 PCIe I/O drawers • 22 dedicated I/O offload processors (SAPs) pre-allocated per system
- 6. What runs on a mainframe? 6 • Linux! ○ SLES, RHEL, and Ubuntu, plus Debian, ClefOS, openSUSE, Fedora, & Alpine ○ Linux with KVM for virtualization (alternative to z/VM, below) • Several proprietary mainframe operating systems, including: ○ z/OS ○ z/VSE ○ z/TPF ○ Z/VM
- 7. Open Source Legacy: SHARE 7 In 1955, the volunteer-run SHARE Inc was founded by users of the IBM 701. A key resource for this organization was the SHARE library of software that systems programmers would share among their peers, freely. In 1959, SHARE released the SHARE Operating System (SOS), one of the first true "operating systems"1 and Wikipedia says of SOS: "SOS was one of the first instances of "commons-based peer production" now widely used in the development of free and open-source software such as Linux and the GNU project." 1 https://en.wikipedia.org/wiki/SHARE_(computing)
- 8. Open Source Legacy: VM 8 Collaboration between organizations, including companies, universities, and government entities has continued through the decades in communities like VM1. In Melinda Varian’s VM and the “VM Community: Past, Present, and Future”2 paper, she highlights key moments in VM history and the parties involved. Psst, IBM was not always on board with virtualization, but the VM community was, in the 1970s. 1 https://en.wikipedia.org/wiki/VM_(operating_system) 2 http://www.leeandmelindavarian.com/Melinda/
- 9. Open Source Legacy: Linux 9 Started out as the "Bigfoot" (i370) port by several community members in 1998-99. IBM released the first Linux kernel patches to support s390x in December 1999. In October 2000, SUSE Linux Enterprise Server became the first, still in production, enterprise Linux to support s390x. Red Hat quickly followed as the second, still in production, enterprise Linux for the mainframe. Ubuntu support was announced in 2016 and began with Ubuntu 16.04.
- 10. Linux Today 10 In 2015, IBM released the first Linux-only mainframe, the IBM LinuxONE. It was announced at the Linux Foundation’s LinuxCon 2015. Today’s LinuxONE is in its third iteration, with the LinuxONE III released in September 2019. (Don’t worry, I’m not here to sell you one, but I can get you free access… stay tuned!) 2015: LinuxONE Emperor & Rockhopper 2017: LinuxONE Emperor II & Rockhopper II 2019: LinuxONE III

Editor's Notes
- #12: - We have a large and growing ecosystem of open source software for IBM Z & LinuxONE - This slide represents only a partial list of all the open source software available in IBM Z & LinuxONE - No different to other processor architectures like ARM or x86, software for IBM Z & LinuxONE also known as s390x requires Linux distribution compiled in the corresponding processor architecture. - We have a team of IBM upstream engineers that are constantly porting and validating new versions of open source software or adding new open source software. - Outside IBM the open source community has ported and validated hundreds of open source software for s390x. - This open source software for s390x, is available in GitHub, individual software distribution sites or in Docker Hub. * ClefOS (the goose), it is an open source Linux distribution for Z based on RHEL/CentOS
- #13: - Docker Hub is the world’s largest repository of container images with an array of content sources including container community developers, open source projects and independent software vendors (ISV) building and distributing their code in containers - This slides represents Open Source Software for IBM Z and LinuxONE available in Docker Hub as Official Docker Images Docker Official Images are a curated set of open source software and "drop-in software” published by Docker There are many more images available in Docker Hub, more than 4,800 images. Over 70 official Docker images
