Regarding synchronous RESTful communication ...

Response to https://twitter.com/jeffreymaxwell/status/705760483391963136 requiring more than the 77 characters left on Twitter.

DISCLAIMER: The quality of writing and thinking here is aligned with a Twitter conversation, not a blog post, presentation, or book ;-)

Synchronous RESTful communication between Microservices is an anti-pattern ... you seem to being saying that the Netflix architecture (hystrix, eureka, ribbon, ..) is broken ... hmm what would @benjchristensen say?
