Meh. As long as you’ve got a good, typed interface for passing messages between them and for having a common understanding of (and versioning system for) key data structures, that’s fine for this sort of thing where it’s largely processing steams of small messages and events. … but it’s probably JSON and some JSON-Schema-based “now you have two problems” junk instead of what I described. In which case, yeah, ew, gross. Unless they’ve made some unusually good choices.
