Mainframe, MVS and zOS Discussion

How is scope of mainframe in market ? Friends and cousins are asking me to move out of mainframe and move in to latest technologies like Java , please suggest what should we do?

Why not learn to use Java on the mainframe? Java has been supported on z/OS since something like 1998. The mainframe also supports most of the current "hot" development tools including Perl, Python, and Ruby on Rails.

That's a good idea, but I'll still remain a mainframe resource that way, right?

I think the question is more what YOU want to do and how you want to be categorized. IT executives repeatedly say in surveys that their company use of mainframes will continue for 10 ... 15 ... 20 years or more so moving away from mainframes may, at some point, limit your career. A December 2022 article from Deloitte https://www2.deloitte.com/us/en/insight ... rends.html said that 90% of business and IT executives expect to EXPAND their mainframe footprint. So a year ago, 90% of business and IT executives think mainframes will continue to be viable in the future.

Have you considered exploring Java and other modern technologies on the mainframe, allowing you to leverage both worlds?
