Hi Cristiano,
how frequent do your service endpoints change? Due to its excessive
caching, DNS is not a good fit if your endpoints change permanently. On
the other hand, if your services are fairly stable and you need almost
linear scalability, then DNS is perfect.
Obviously, DNS is passive. It does not push changes to the service
consumers, which e.g. the Zookeeper ECF discovery provider does.

PS: Note, that the current org.xbill.dns bundle apparently has problems
with Java9. But with Java9 being pretty much in flux, it's possible that
the issues will have disappeared in the final Java9 release.
