add hystrix circuit breaker #33

Closed poblin-orange closed 8 years ago

poblin-orange commented 8 years ago

Hystrix circuit breaker offers a good support in spring cloud, to manage backends timeout, avoid overflowing them in case of slow. see

https://github.com/Netflix/Hystrix/wiki/Configuration
http://cloud.spring.io/spring-cloud-netflix/spring-cloud-netflix.html This instrumentation limits the concurrent iaas request (default is 10 concurrent cpi orders, will tune later).
