	* Helps to avoid cascading failure into Micro Services		Helps to avoid cascading failure into Micro Services
			===== Pattern =====
			* By creating a GateKeeper wich is an Interceptor that intercept all the requests going through
			* it can be configured and it has to keeps track of the lasts N successfull and failed requests
			* Whenever there is an issue with the associated service, the interceptor will stop
			* So the interceptor will not allowed any subsequent requests, instead it will immediatly send back a default response
			* A time is configured to allow the requests to go through after the service has recovered
			** it can be configured as allow partial to test the service with few request before to allow all the request again
