How to build microservices

776 views

Published on

We hadden webservices, wcf services en rest services, maar die waren het allemaal net niet. Gelukkig zijn er nu microservices. En iedereen leefde nog lang en gelukkig. Of toch niet? In deze sessie kijken we hoe we kunnen falen en slagen met microservices. Waarom er door verstokte oude mannen wordt gezegd dat microservices zijn hoe ze een service geörienteerde architectuur altijd bedoeld hadden. Waarom het definiëren van je bounded context zo ontzettend belangrijk is. Omdat je dan het verschil kunt maken tussen het opnieuw bouwen van een monolith vol microservices of een goede architectuur.
