However, management here has decided to "sunset" the z. Period. No discussion. Even if it ends up costing more money after it is "converted to the cloud", though they insist that it won't. Long term, I think the company wants to "cloud-source" all of IT. Or at least all of the "infrastructure" such as servers. I don't have any idea about desktop support, help desk, et al. Lack of need to know. My dream job would be one where I'm a sysprog-equivalent at a company which has 1+ z13 running z/OS, z/VM, and z/Linux and would allow me to "get my fingers" into each of them, at least a bit.
