I did have an interesting conversation with a customer recently where given ESG they wanted to move relevant workload to zLinux because the power / VM / container ratio was lower than an x86 farm to lower their carbon footprint; I’m not sure if this is an edge case or not.
For many Z customers they do want their supporting software on their platform to ensure that they have control over those services. Again, its a personal choice. My strategy is to move all functions that do not need to run in z/OS available in containers on any platform the customer chooses to optimize their cost on Z. Exciting times.
