Architecture Microservices


PARIS - FRANCE

• Martin Flower & James Lewis (http://martinfowler.com/articles/microservices.html)« The microservice architectural style is an approach to developing a single application as a suite of small services, each running in its own process and communicating with lightweight mechanisms, often an HTTP resource API. These services are built around business capabilities and independently deployable by fully automated deployment machinery »

• Objectif : construire des Applications / Systèmes…– Plus robustes– Plus scalables– Plus évolutifs– Plus denses
