Jerome Dubreuil and his colleagues on the SAMI (Samsung Architecture Multimedia Interactions) team at Samsung saw a number of technical obstacles holding IoT developers back. The SAMI group made some key architecture decisions in the earliest days of building out an innovative ioT data platform, and from day one they knew that they would be building their platform following Reactive principles. Central to their efforts were the Scala and Play Framework for rapid prototyping and developer productivity, and Akka for the data transformation and WebSocket layers. Our case study looks at some of those key decisions that allowed SAMI to ship such an ambitiously scoped platform in less than two years.
