Definition

“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. There is a bare minimum of centralized management of these services, which may be written in different programming languages and use different data storage technologies.” (Martin Fowler & James Lewis 2014)

Starte da wo du stehst (Reifegrad)

Übe was weh tut (Katas)

Nimm dir Zeit für Infrastruktur

Automatisiere ALLES (build, release, configure, test)

Betrachte Infrastruktur als Code

Verwende die Cloud wenn möglich (PaaS, Container)

KISS (right technology for the problem on hand)

Liefere mehrmals täglich aus (Feature switches, A/B Testing)
