  TIP: The ``service`` part is used to discrimintate aginst the services but if not provided it acks like a wildcard so each non named service will be returned whatever the service name is. This is useful if you ahve a single service so the service name is redundant.
  
  NOTE: this implementation is provided by ``camel-core`` artifact.
  
  
negative.code: === Load Balancer
  
  The Service Call EIP comes with its own Load Balancer which is istantiated by default if a custom is not configured and
  glues Service Discovery, Service Filer, Service Chooser and Service Expression together to load balance requests among the available services.
  
  If you need a more sophisticate load balancer you can use Ribbon by adding camel-ribbon to the mix,
