The Open Mainframe Project Zowe technology is celebrating its 7th year since it was first launched with the mission to make z/OS easier and more familiar to operate to folks who hadn’t grown up with the platform. This talk will show the scenarios that have gotten market traction with customers and will be co-presented with Emma Skovgard from Dank Bank. These range from ad-hoc scripting, automation, DevOps pipelines and CI/CD with or without Ansible and source code management repositories, as well Visual Studio and IntelliJ extensions opening the aperture on mainframe file access by bringing these powerful IDEs into the field of play. By leveraging VS Code alongside other open source tooling it’s possible to build a modern intuitive software stack that not only opens up the world of JCL, REXX and CICS to rich GUI development, but brings into play python, GoLang, node.js and newer unix based languages and runtimes.
