While the mainframe is powering the world's most critical system the words "modern", "open source" or "generative AI" typically don't come to mind. So lets change this!To do that simply tune in to our latest episode where we have Jessielaine (Jelly) Punongbayan, Sr. Technical Support Engineer at Dynatrace, telling us why she is excited about the modern Mainframe and how it brought her from the Philippines via Singapore and Czech Republic to Austria. We learn about all the open-source projects and communities she is involved in such as Open Mainframe or Zowe that make it easy to connect the Mainframe with the modern tooling of today's development environments. Jelly shares her stories about the role of good observability, how it connects the distributed and the mainframe world and how it enables development teams to build more efficient systems. And what about AI? Well - you have to tune in and listen to the end!Here the links discussed in the episodeWriting a COBOL program using VSCode: https://medium.com/modern-mainframe/beginners-guide-cobol-made-easy-introduction-ecf2f611ac76 Using CircleCI to perform automation in Mainframe: https://medium.com/modern-mainframe/beginners-guide-cobol-made-easy-leveraging-open-source-tools-eb4f8dcd7a98 Using OpenTelemetry to capture Mainframe Insights: https://medium.com/@jessielaine.punongbayan/re-imagining-mainframe-insights-through-open-source-tooling-79dd4c937114Dynatrace support for Mainframe: https://www.dynatrace.com/technologies/mainframe-monitoring/
