  +It's nice to have an async interface for our service, but it's time to implement it. We are going to implement three
   methods in this service:
   
   * `getPortfolio` to understand how to create `AsyncResult` objects
  
positive.code: 
  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:
  
  [source, java]
  ----
  HttpEndpoint.getClient(discovery, new JsonObject().put("name", "CONSOLIDATION"), // <1>
    client -> {
  
negative.code: <2> The client cannot be retrieved (service not found), report the failure
  <3> We have the client, let's continue...
  
  Here is how `computeEvaluation` method is implemented:
