I've been researching a lot on Akka for the past few weeks and understand the obvious benefits of using Akka in Scala & Java applications. But there are too many simple examples on building Chat, Greeting & Ping-Pong applications and I can't find anything on implementation of good practices or architecture to build real world business applications using Akka Actors.
Question: How can businesses today build lean applications exposing their business RESTFul web services with just Akka & Akka-http (spray.io) instead of using the most commonly used 3 tier layer architecture in Java today
ReactJS (FLUX) will be used for front end development. So I'm trying to find the answer on how to architect just the Business and Database layer using Akka and Akka-http without using Play or Lift or any other framework to keep things lean and simple ?
