   That's a bit more tricky, so let's do it step by step. First, in the `evaluate`, we need to retrieve the HTTP
   endpoint (service) provided by the quote generator. This service is named `CONSOLIDATION`, and will be imported by
  -Docker. We are going to see this in details in 5 minutes. So, let's start to get this service:

  Let's now implement the `computeEvaluation` method:

negative.code: === Data objects
  
  The `Portfolio` object is a data object. Event bus proxies support a limited set of types, and for non-supported types,
  it must use _data objects_ (please check the http://vertx.io/docs/vertx-service-proxy/java/[documentation] for the whole list
   of supported types). Data objects are Java classes obeying to a set of constraints:
  
  * It must be annotated with `DataObject`
