Where do I fit a Restful API in this kind of architecture?

Hopefully once the services are well defined, we’ll have the Source of Truth for each of them, this allows data to be mutated by that service, and only that given service. This means this service can do the data change, propagate an event and move forward. Ideally without dual-writes The read APIs can be done on the same service on even another one, it’ll depends on the system throughput and separation of those two concerns. If you’d like more details on this please ask

Thanks for your response. Do you have a Restful API example of your own?

I can bring one during the webinar next week 😄

That would be great. When is this webinar and where can I find it?
