If I had to build an app, here are some architectures I'd consider:

1 Monolith

↳ Run everything together as a single service.

2 Modular Monolith

↳ Deploying loosely coupled modules together.

3 Microservices

↳ Loosely coupled, independently deployable services.

4 Serverless

↳ Running code without provisioning servers.

5 Event-Driven Architecture

↳ Services that emit and react to events.

Remember, every architecture has tradeoffs.

What else should make this list?
