WHAT IS A MICROSERVICE?TITLE PRESENTATIONMay 16, 2017
WHAT IS A MICROSERVICE?TITLE PRESENTATIONMay 16, 2017
WHAT IS A MICROSERVICE? “Microservices are a thing these days.”Phil Calçado, former Director of Engineering, SoundCloudTITLE PRESENTATIONMay 16, 2017
WHAT IS A MICROSERVICE? “Microservices are small, autonomous services that worktogether.”Sam Newman, ThoughtworksTITLE PRESENTATIONMay 16, 2017
WHAT IS A MICROSERVICE? “Loosely coupled service-oriented architecture with boundedcontexts.”Adrian Cockcroft, Battery VenturesTITLE PRESENTATIONMay 16, 2017
WHAT IS A MICROSERVICE? “A microservice is an independently deployable component ofbounded scope that supports interoperability throughmessage-based communication.”“Microservice Architecture-Aligning Principles, Practices, and Culture”TITLE PRESENTATIONMay 16, 2017

SUMMARY Building complex applications is not an easy task.The Monolithic Architecture pattern only makes sense forsimple, lightweight applications.The Microservices Architecture pattern is the better choice forcomplex, evolving applications, despite the drawbacks andimplementation challenges.Probably the best way to define boundaries for microservicesis by using Bounded Context from DDD (Domain DrivenDesign)5/16/2017
