Hi Mark. Nice one, appreciate it. However, in my opinion event-driven architecture is not kind of architecture itself and just communication method. Can we use event-driven communication in microservices? Yes. And what about using it in modular monoliths? Again, we can use it.
When EDA is used with other styles we form hybrids, such as event-driven microservices or event-driven space-based architecture. Although it is a common pattern to leverage events for parts of a system in other architectures, you can build a software architecture using EDA only (I have build lots of these), thus IMHO making it a separate architectural style.
@@markrichards5014 you mean monetary cost? Can you please elaborate how modularity increases the cost? 🤔 do you mean just cost for development effort to make the system modular or does it increase the cost in any other way, too?
@@mahdi5796 The primary benefits of architectural modularity are found in distributed architectures, which as generally more costly to create and maintain than monolithic ones. That said, modularity can be realized in a modular monolith and microkernel architectures, which increase overall agility but not operational characteristics.

Mark, a preview of Alistair Cockburn's "Hexagonal Architecture Explained" is out now. Where would that sit in your star rating?
Similar to microkernel architecture, where the plug-in components act as ports and adapters.
Thanks Mark. But as you said "Everything is trade-off". So, what are trade-offs of modularity? It can't be all good 😉
Nice! Cost and complexity are some of the tradeoffs of modularity, particularly as you move into the distributed architecture side of things
