@@mauroservienti I really like your diagrams! Are they of some specific type (do they have a name) I can read and learn about? Thanks!

by doing pure events(not orchestrator) nobody know what going on. down the road what will happen. what if there is one more step between finance and shipping for example: fraud detection - now you need to change the shipping to not listen to finance and reservation any more instead listen to fraud detection

Thanks for the comment. Yes, that's correct in a distributed system one of the biggest disadvantages is that it's harder to get an overall picture of what's going on. On the fraud detection part, it really depends on how it's implemented. Fraud detection could be implemented the way you suggest or by changing only finance. Finance "invokes" fraud detection as part of the payment flow and only if everything is fine publishes the event that eventually triggers shipping. In such a way shipping remains unaware of the fraud detection step.
