title: Communication between Microservices: Spring cloud OpenFeign vs WebClient/RestTemplate
body: <p>Any idea please about the best way to use for back to back communication ?</p>
  <p><strong>spring cloud OpenFeign</strong> or <strong>WebClient/RestTemplate</strong> ?</p>
  <p>I think <strong>Feign client</strong> should be used when spring cloud gateway need to</p>
  <p>communicate to other microservices, whereas <strong>WebClient/RestTemplate</strong> should be used for back to back communication.</p>
  <p>Am I wrong ?</p>
