J-Fall 2017 Speaker Lucas Jellema – Event Bus as Backbone for Decoupled Microservice Choreography

Microservices are independent, encapsulated entities that produce meaningful results and business functionality in tentative collaboration. Events and pub/sub are great for allowing such decoupled interaction. Using Apache Kafka as robust, distributed, real-time, high volume event bus, this session demonstrates how microservices packaged with Docker and implemented in Java, Node, Python and SQL collaborate unknowingly.
