I am not a "corporate shop" guy but apparently "put up a VM LPAR" is a huge political leap for many z/OS shops. The idea is facilitating "if we could just get one instance of Linux up under z/OS we could show that to senior management and take it from there." Hence zCX.

No extra external tooling is needed; just use out of the box management apps that are already available. Plus, the system programmers have much greater and finer, control over the hardware resources (memory, CPU, etc.) each zLinux guest is allowed to consume. And of course, z/VM and zLinux run very well on the full speed IFL engines, no other specialty engines required. Connect the z/VM and z/OS LPARs together by hyper-sockets and you're good to go. If I was an z/OS shop looking towards Linux, that's how I would proceed. Thought and comments always welcome.
