Keeping up with the pace of change in emerging technology is an ever present challenge for enterprises. Trying to build systems that age and evolve gracefully over time is not a small task. We are all familiar with frameworks that help us implement architectural patterns, especially application architecture. In this session we will investigate Lagom, a new class of framework designed for system building, specifically, Reactive Systems. I will discuss common challenges I’ve encountered implementing large scale Reactive Systems and review Lagom features designed to address these challenges head-on. Though an investigation of this Scala-based framework, we will learn how system-building frameworks help Enterprise Architecture to rise to the challenge of aging like wine.
