According to today’s announcement, Lightbend is changing Akka’s licensing to “Business Source License (BSL)”. This is not an Open Source, or a Free Software license. This is a proprietary license.
It’s a prominent framework for basically implementing distributed applications in JVM languages (Java, Scala, Kotlin etc.).
It contains an implementation of the actor pattern (a more sophisticated, but long-term simpler way of doing multi-threading), clustering of distributed applications, data streaming and more.
Basically, if you want to write a production-ready distributed application, you currently use either Akka or Erlang (which is a whole separate programming language).
