David, I have been in mainframes since 1970 and started my own company in 1998 dealing with mainframe modernization. A lot has to do with languages, databases and interfaces to non-mainframe environments along with the zCloud capabilities currently available. While I am a 1,000% proponent of mainframe environments, I do see where some smaller applications make it possible to have more readily support and services by moving off the mainframe. Almost without question, one of the issues is the aging of mainframe staff. But on the flip side, converting to a more "modern" language, migrating from a non-relational DBMS to DB2 and improving the containerization of mainframe applications vastly improves the ability to interface to other environments, support, access to adequate staff and all the IBM and 3rd party tools that also improve the longevity of the applications. Lastly, modernization can also involve the replacement of tools and utilities that don't perform adequately, are too costly or are not kept up to date to match the capabilities of the current zOS systems.
All I do with my current employer is analyzing mainframes for modernization opportunities. Very, VERY few mainframe shops want to lose their mainframe. And, all the mainframe TBTF environments can't move to a non-mainframe infrastructure just because they are so large. Just my thoughts....

It seems to be catching on with the Bobs but when you ask exactly how they propose to modernize their systems all you get is silence. As in if you don"know we shouldn't even be talking about it. Any ideas ? Or is it just more BS like 'cloud' or 'devops'? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
