Mainframe, MVS and zOS Discussion

Hi All,

Though it is possible to develop microservices on Mainframes as well as as400 why is it that customers are wanting to develop microservices outside legacy platforms rather than doing it within IBM i or IBM z

Any answers would help.

I suspect that if you talk to 10 companies, you would get at least 10 different answers to that question. In general, companies that don't develop on legacy systems do so for a variety of reasons: perceived cost of legacy systems, desire to get rid of legacy systems, perception that legacy systems cannot do "modern" development, perceived cost of legacy systems development, company inertia, company lack of familiarity with micro service development and so forth. Your question cannot really be answered without referencing a specific situation since the answer can vary so much.

May you are right that there is a lot of misperception about it. In our company they waned to develop microservices outside legacy platforms, that's the only statement we hear.
