Cooking your Ravioli “al dente” with Hexagonal Architecture

June 14, 2021 12:00 - 14:00 CEST

Hexagonal architecture (a.k.a. ports and adapters) is a fancy name for designing your application in a way that the core domain is separated from the outside world by input and output ports. With a little bit of imagination one can visualise this as a hexagon made up of domain objects, use cases that operate on them, and input and output ports that provide an interface to the outside world.

Many projects involve integration or communication with external software systems. Think of databases, 3rd party services, but also application platforms or SDKs. Such integrations and dependencies can quickly get in your way, clutter your core domain and reduce the testability of your core business logic. In this talk, I will demonstrate how a hexagonal architecture helps you to reduce dependencies on external software systems and enables you to apply standard software engineering best practices on the core domain of your application, such as testability, separation of concerns, and reusability.

Join this talk to learn the ins and outs (pun intended) of the hexagonal architecture paradigm and get practical advice and examples to apply to your software projects right away.
