Frank DeGilio, Distinguished Engineer and self proclaimed CTO for Mainframe “Declunkification”, introduces the topic of Z Modernization.

Cloud Application Developers don’t need to learn z/OS, they can use the languages they are already familiar with and in doing so, make the mainframe an important player in their CI/CD pipeline. Z Modernization: Maintains all the things that make z/OS enterprise grade while exposing them to a whole new community of users.
