c# - How to deal with multiple NServiceBus instances -

first let me give context. i'm working on project company a. company part of bigger organisation z. both companies have own nservicebus solutions sql server transport , persistence. need somehow make possible both companies able talk each other via nsb - how do that?

one solution proposed intermediate database messages -> z stored. 2 handlers:

• first receive message a's nsb , store in db
• second read db , place z nsb

other solution more have relay handler receives messages , z.bus.send(message_from_a)

you can use gateway send messages on http.

what kind of interaction want achieve?

take @ introduction gateway

and he gateway , multi-site distribution
