3. For the last 20 years, The Linux Foundation has provided unparalleled support for open source communities
through financial and intellectual resources, governance structure, IT infrastructure, services, events, and
training.
Dedicated to building sustainable ecosystems around open source projects, The Linux Foundation is working with the global technology
community to solve the world’s hardest problems through open source and creating the largest shared technology investment in
history.
The Linux Foundation is the umbrella organization for more than 300 open source projects accelerating open technology
development and commercial adoption. Some of the game-changing initiatives hosted by The Linux Foundation include:

Open Mainframe Project - part of The Linux Foundation
ecosystem of sustainable open source

4. Mission of the Open Mainframe Project:
Build community and adoption of Open Source
on the mainframe
• Eliminating barriers to Open Source adoption on the
mainframe
• Demonstrating value of the mainframe on technical and
business levels
• Strengthening collaboration points and resources for the
community to thrive

7. Supporting a strong open
source ecosystem on
mainframe is crucial to
sustainability. The Open
Mainframe Landscape is
key to identifying and
understanding the
dynamics.

8. Ambitus
Joe Bostian, Open Source and Analytics
Architect for IBM z Systems and co-lead of
OMP’s Ambitus project

9. https://www.openmainframeproject.org/projects/ambitus
Mission:
To build a community of users who want to better understand how their existing open source environment
can be implemented and operated on a mainframe. This is a community of architects, developers, and users with
experience in enterprise environments who need to use their z/OS or Linux on Z platforms more effectively through
cross-platform open source frameworks and interfaces.
Benefits:
● Understand the set of common open source environments that exist on the modern mainframe
● Gain access to examples and best practices that illustrate how mainframes excel in open environments
● Discover how to to eliminate inefficiencies in enterprise open source deployments by applying the unique
functional strengths of IBM Z
What’s next:
We will continue to build out our portfolio of open source configurations and library of how-to information to assist
new users in bringing their workloads to IBM Z. We will also be providing assistance to open source maintainers
and committers who are thinking about supporting IBM Z through their projects.

10. Feilong
Mike Friesenegger, Solution Architect for the
SUSE Alliances team and co-lead of OMP’s
Feilong Project
James Vincent, Senior Systems Architect for
Velocity Software and co-lead of OMP’s Feilong
Project

11. https://www.openmainframeproject.org/projects/feilong
Mission:
• Contribute and further develop the RESTful API server that simplfies interaction with the IBM z/VM hypervisor.
Benefits:
• The RESTful API server makes using z/VM easier especially for developers without deep knowledge of z/VM.
• Develop self-service Infrastructure-as-a-Service automation of VMs, networking and storage used by z/VM.
• The z/VM Cloud Connector is included in an IBM product and can be integrated with VMware and OpenStack.
• An implementation of the RESTful API is available in a third-commercial z/VM cloud management product.
What’s next:
• Already have a strong codebase to contribute and further develop thanks to the IBM contribution to the project.
• Move CI/CD infrastructure under Linux Foundation and connect to Z resources from Feilong partners.
• Provide Feilong contributors access to z/VM resources to develop, test and document features.
• Support OMP summer mentorship project - Feilong - Ansible Module.
• Increase the Feilong membership and bi-weekly project meeting attendance.

13. Polycephaly
Jerry Edgington, Senior Systems Analyst at
Western & Southern Financial Group and lead
for OMP’s Polycephaly project

14. https://www.openmainframeproject.org/projects/polycephaly
Mission:
- To allow developers to be just developers, regardless of what platform the application is being developed for
- Minimal knowledge for z/OS system programmer to support
- Reuse existing Jenkins and Git knowledge to support the zSeries platform
Benefits:
- Requires minimal z/OS system programming experience
- Treats z/OS just any other platform
- Reuses technology most likely already running, with expertise to use it
- Quickly allows non-z/OS developers to develop on z/OS
What’s next:
- Expansion of the current code to base to allow for more features, functions and subsystems, like DB2
- Improved integration with Jenkins and its code, and exploiting more of its features
- Improve documentation to allow for easier installation and transition to Polycephaly

15. Zorow
Hiren Shah, Senior Technical Staff Member, IBM

16. https://www.openmainframeproject.org/projects/zorow
Mission:
● Provides a repository for z/OS systems programmers and product vendors to contribute and share z/OSMF
workflows
● Build community of z/OS System programmers to collaborate around z/OSMF workflow technology
● Modernize z/OS System management via use of z/OSMF and workflows
Benefits:
● We can centralize workflows from clients and numerous IBM offerings, for common systems management tasks
● Systems programmers can collaborate on various workflows to reduce complexities by using familiar templates
that integrate seamlessly with their respective enterprise operations.
● Tenured systems programmers can be energized to transfer their systems management skills to the early
tenured systems programmers
What’s next:
● Continue to build portfolio of various system management and configuration workflows
● Encourage customers to participate and contribute to the zorow community
● Provide educational materials such as videos to help customers to build their own z/OSMF workflows

17. https://www.openmainframeproject.org/projects/zorow
What is a z/OSMF Workflow:
The z/OSMF Workflow is a framework that supports z/OS System Programmers (Workflow provider) to define a
guided flow (workflow) through steps to accomplish a system management or configuration task.
The z/OSMF Workflow is useful to:
● Assist people unfamiliar with how to perform a given task, or a task that they perform rarely
● Ensure that all tasks are performed in the right order and only when their dependencies have been met
● Ensure that all steps are completed, even if many of the tasks have been delegated to a number of different
colleagues
● Monitor and track progress toward the completion of the task
● Provide a history (audit trail) of the steps performed for a task
● Perform the same tasks on multiple systems
z/OSMF workflow Examples:
● Provision z/OS middleware
● Expand zFS file system
● Upgrade z/OS version

18. Zowe

Broadcom and member of OMP’s Zowe
Leadership Committee

19. zowe.org
Mission:
● Reduce the learning curve
● Attract new people to z/OS
● Simplify architecture
Benefits:
Zowe is an integrated and extensible open source software for z/OS with a coherent and curated set of user and programmatic interfaces
that:
● Provide consistent access to z/OS systems and services
● Leverage industry standard methodologies and standards familiar to the vast majority of today’s developers and IT staff
● Are commonly accepted as a standard within the mainframe community
What’s next:
● SSO experience for all users of z/OS
● SDKs for popular languages/runtimes like Python and Node.JS enabling developers to easily with z/OS services
● Mobile Framework for z/OS Services

26. Zowe
Conformance
Joe Winchester, IBM Senior Technical Staff
Member and member of OMP’s Zowe
Leadership Committee and Zowe architect

27. https://www.openmainframeproject.org/projects/zowe/conformance
Mission:
● Zowe is designed and architected to be software platform for z/OS products to build plugins, apps and
extensions.
Benefits:
● Give users the confidence that when they use a product, app, or distribution that leverages Zowe they can
expect a high level of common functionality, interoperability and user experience.
● Conformance provides Independent Software Vendors (ISVs), System Integrators (SIs) and end users greater
confidence that their software will behave as expected.
● The Zowe Conformance Program is administered by the Open Mainframe Project
