This talk covers the challenges customers have faced with obtaining and deploying tooling for their mainframe developers and system programmers over the last 50 years. The Zowe Community and Open Mainframe Project are working with ISVs and customers to address this and create modern platforms and frameworks by bringing open source languages and tooling to the mainframe. Co-presented with Broadcom and Rocket Software, attendees will learn how a blend of open source tools together with Zowe, the new open source framework, empowers mainframe developers.

1. IBM Z – To Open Source
and Beyond
Joe Winchester – IBM
2. The traditional mainframe
• 55 years ago the mainframe was created
– Code written then still runs now
unmodified
• s360 was named after 360 degrees – full
compass orientation coverage
• Mainframes helped the Apollo program
put humans onto the moon in 1969
3. The modern mainframe
• 70% of the world data is stored in
mainframes
• Used by 25 of the world’s top banks and
70% of Fortune 500 companies
• Mainframes process 30 billion business
transactions per day around the world
– 68,542 google searches every second
globally vs 1,200,000 on mainframe
– 68% of world’s production workload
capacity, 6.2% of total server spend
• Mainframes have pervasive encryption
at rest and in flight.
4. Open source and mainframe
• Multi language server with
older languages (COBOL,
PL/1) side by side with newer
languages (Java, node, Swift,
Pytho, …)
• z/LINUX and z/OX
Container Extensions
8. We are building more than just technology
We are building a community
