Liferay 7 - microservices for the enterprise

This is an overview of microservices characteristics and how those are quite similar to the concept of (micro?) services in OSGi. It then goes one step further to demonstrate how one can benefit form the concept in an enterprise class solutions like Liferay Portal 7.

12. . . . The Deployment Model is a Detail. . . . there is no such thing as a micro-service architecture. Micro-services are a deployment option . . .

Componentization via Services Organized around Business Capabilities Products not Projects Smart endpoints and dumb pipes Decentralized Governance Decentralized Data Management Infrastructure Automation Design for failure Evolutionary Design 50% not strictly software but rather operations related!
