Reading Time: 4 minutes What is Lagom? Lagom is not in disguise anymore. Everyone who’s following on micro-service architecture knows about Lagom framework. Lagom is an open source framework built with the shifting from monoliths to micro-services-driven application architecture in mind. It abstracts the complexity of building, running and monitoring micro-services driven applications. The Lagom framework includes Java and Scala APIs to simplify development of microservices. Lagom helps us Continue Reading
