Microservices and Modularity - The Difference Between Treatment and Cure

Explore the world of microservices and modularity in this 58-minute Devoxx conference talk. Delve into the complexities of modern software architecture, comparing microservices with modular approaches. Learn why experienced developers might be skeptical of the microservices trend. Follow a live demonstration showcasing various methods to modularize existing Java EE applications, progressing from monolithic Glassfish EJB/JSF structures through SpringBoot and OSGi, culminating in a distributed system with a portal front-end. Gain insights into domain model changes, OSGi implementation, portlet development, and distributed computing. Understand the importance of modularity, the benefits of OSGi, and the role of Liferay in modern software architecture. Conclude with a Q&A session to address your specific concerns about microservices and modular design.
