FP influenced architectures

Let’s discuss a few popular architectures that borrow ideas from FP.

• Domain driven design (DDD)
• Event based architectures
• CQRS
• Functional reactive architecture

Let’s start with DDD.

Note

Other names for DDD include Hexagonal Architecture, Clean Architecture, Ports and Adapters, Onion Architecture and Applicative-Style-Architecture. We'll call it DDD or layered architecture.
