I believe the mainframe (and z/OS) will be here for a long time to come. But, I also think the smaller installations like mine are increasingly toast. The z/OS software charging models just don't work with the increasing minimum capacity of z machines.
Sometime within the next 12 months, I am certain we will shut down our z/OS LPARs. When I came here for college in 1976, they were running what was described as loosely coupled 370s. People working here had stories of changing the wires to program the earlier machines and the CE talked about replacing tubes. Amdahl was here for a while, then back to IBM. A 3090-400J was replaced by a Mulitiprise 2003 and then a series of zmachines. The last onsite machine was a 10 year old z7. Late 2017, We migrated via lift'n'shift to a Mainframe as a Service installation. We never ported code to the new systems that have replaced the functions formerly performed on the mainframe. These were in-house developed (Primarily Adabas and Natural) and maintained. Adabas and Natural landed here late 70's/early 80's. Instead, the business functins wee moved to ERP and other "cloud" services. Student Systems moved (Peoplesoft) around 2007/2008. Financials (Workday) 2019/2020. I think discussions about ERPing became early this century, z/OS still runs to provide access to historic data. Most of which has been copied elsewhere for continued query. I've had a good run, but I doubt there are many jack of all z/OS, master of none positions in today's workplace. But, still many opportunities for working on the platform. > -----Original Message----- > From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> On > Behalf Of Enzo D'Amato > Sent: Saturday, June 18, 2022 2:23 PM > To: IBM-MAIN@LISTSERV.UA.EDU > Subject: Re: Modernize Mainframe Applications for Hybrid Cloud with IBM > and AWS > > I also agree, but as a non-insider, I wanted to know what others were > thinking.
