I need some suggestion on mainframe migration project.
I have mainframe application called as 'A' where some of the functionality is moving into another system called as 'B'.
There are scenario where application A perform certain events by means of existing programs. I need to suggest options to pass this events updates to another application 'B' synchronously. I don't expect response on this events from application B. I can see web service call and MQ as an options.
Could you anyone suggest all pros and cons of both approach ? also any other way to reduce cost of development ?
