Re: How companies are moving on from Cobol?
And no one explains the cost of still needing to run about 20% of your workload on a mainframe after the easy 80% has been replatformed. Mainframe pricing is all about scale. After that, the customer gets frustrated and no longer has the skills in house so they wind up spending more to let someone else run the environment and all the consultants walk away with some nice profits. I've watched the process repeat itself many times, and it always seems to end the same way. Now if you start with the harder 20% (re-write or buy a commercial off the shelf (COTS) replacement) for the service while accepting your new cost structures On Tue, May 11, 2021 at 9:04 AM Ramsey Hallman wrote: > About 10 years ago I was working at a firm in Southern California.

Re: How companies are moving on from Cobol?
About 10 years ago I was working at a firm in Southern California. They hired a new VP over the technology area. His goal in life was to get off the mainframe. He convinced the powers above that he could run the entire workload currently on a S/390 on a quad processor running Windows, saving the company tons of money. One of the many things people who suggest migration off of mainframes fail to realize is that you can run big iron at 100% all day long with no real impact. You can run a Windows or Unix box at only about 50% max, maybe 60%. 128 quad processors later, and an increase in the budget of almost $2M over the mainframe, they still could not handle the workload. I have no idea where the insanity ended (I left the firm for another job, having no interest becoming a Windows admin as opposed to an IBM s/p). The last I heard some years ago, they were still running z/OS on a small box because one of the major systems written in assembler absolutely could not be replaced/reproduced in any software that provided the response times required for that application. Wonder where they are now and what the IT budget is.

Re: How companies are moving on from Cobol?
It would be interesting to see the true cost after migrating to the new systems. 20 years ago I remember seeing a comparison which showed going off the main frame was going to save Mega bucks for someone. When you dug into it little things like 1. They had configured a top of the range z/OS box and it ran at 10% The mid range boxes were spec'ed just right. 2. With the mainframe the costs included backing up data, and taking tapes off site etc. The midrange did no backups. And so on... But let's not look at the facts too closely ... the director said "let us look Strategically!"I met people from the company a few years later. They were not happy bunnies - "with z/OS it just worked" they sighed into their beer.

Re: How companies are moving on from Cobol?
Now it's popular "how to survive in cloud environment". I used to ask "why do you want to go there?" Answers? From nothing to aggression. BTW: Last few years I had to learn about banking system and Windows. It's not piece of sh*t. It is much worse. They really lack of obvious and basic features like DFSMS, HSM, JES, etc. -- Radoslaw Skorupka (looking for new job) Lodz, Poland W dniu 11.05.2021 o 13:18, Bill Johnson pisze: I love when they call or insinuate that the mainframe isn’t modern.
