Implementing an Event-Driven Microservices Architecture

17 May

6:30 pm Hymans Robertson LLP, One London Wall, London EC2Y 5EA



Web services are typically stateless entities that need to operate at scale. Using the functional paradigm offers benefits like scalability, productivity and correctness.

This talk starts introduces Domain-Driven Design to create Microservice boundaries. Using discriminated unions, the domain model can be captured as code eliminating the need for separate documentation. Moreover, using computation expressions (F#’s monads), one can model custom workflows easily.

It then introduces event-driven architecture, where every external action generates an event that the system responds to. Events act as the notification messages for any significant change in state and may generate other event(s) as services invoke each other.
