My take is that it depends on how you want to architect your microservices. Do you want to manage services with code (Netflix OSS) or with Istio? I think Netflix has proven that the former works. I think Istio is good too, but I haven’t played with it much. If you’re interested in using Istio with JHipster, see Sendil Kumar’s Hello Istio 
, welcome to JHipster.
