Lightbend Lagom: Microservices "Just Right"
summary
Lagom is an open source JVM framework that builds reactive microservices using Akka and Play, with an SBT-driven dev environment where a single runAll command starts services plus embedded Cassandra, a service locator and a service Gateway on localhost:9000. It promotes event sourcing/CQRS with persistent entities, generates events for state changes, supports streamed responses via Akka Streams over WebSockets, includes circuit breakers, and targets production via Lightbend Conductor; current release is RC1.
