public class PingUrl
extends java.lang.Object
implements com.netflix.loadbalancer.IPing

Ping implementation if you want to do a "health check" kind of Ping. This will be a "real" ping. As in a real http/s call is made to this url e.g. http://ec2-75-101-231-85.compute-1.amazonaws.com:7101/cs/hostRunning Some services/clients choose PingDiscovery - which is quick but is not a real ping. i.e It just asks discovery (eureka) in-memory cache if the server is present in its Roster PingUrl on the other hand, makes an actual call. This is more expensive - but its the "standard" way most VIPs and other services perform HealthChecks. Choose your Ping based on your needs.
