The mainframe environment has fundamental specificities that conflict with the conventional DevOps approach as conceptualized in the technical literature. This traditional view of DevOps is a dead end for mainframe systems. In this presentation, I propose to rethink the DevOps cycle in order to reconcile the apparent contradictions between current methods and the inherent requirements of the mainframe development cycle. Above all, why not change our approach to the problem?
