      Description

      Distributed Shell works as an example, but it's not the right architecture for something you'd want in production -instead its design runs a risk of setting a bad example for others to follow.

      Instead it should

      • be decomposed into a set of services each with their own responsibilities
      • split the 'model' of its cluster into its own classes, a model that can then be unit tested outside of the AM
      • factor out all container launching into its own service -and use a thread pool to avoid scalability limits
      • provide a demonstration (classic) RPC service to show how to implement this
      • tests
