I always have to smile that the whole microservices, isn't much different from "The network is the computer", Taligent, CORBA/DCOM, WebServices, SOA,.... with iPaaS products being another go at BPEL.
Maybe Microsoft should bring back Biztalk for agentic workflows.
(To your point...having knocked out CORBA and DCOM, perhaps we may next look forward to SOAP.)
