JPM isn’t replacing their mainframe either. No banks that want security, 
uptime, and transaction processing AWS can’t match are. Wait til IBM’s 2nm chip

How about JPMorgan Chase who also use AWS in their enterprise

You have obviously been out of the industry for a while. The typical 
enterprise IT system these days is heterogeneous. It's all about 
integration. CICS have recently added support for correlation tokens so 
a transaction can be tracked to the source of origin on distributed 
systems.
