Node red is a really nice framework that lets you build IoTs workflows. It is in fact far more interesting than that because you can use it in order to create small workflow integrations as you would do with a product like Mule or Camel. Of course you should not use it if you want to handle critical financial messages using a MQ Series transaction but it can handle most of the less critical cases.

Docker is the best tool to quickly check new technologies without the hassles of installations.
