Arduino Yun Cloud

Does exist an Arduino cloud service to support Yun as an internet-connected thing? or is just a proposal in the forum?

If not, it should be good to have that "Yun Cloud', specially to help the newbies, as a secure environment, during the process of learning/creating their own socket programming over TCP/UDP. regards!

It's just a forum proposal

Hello Federico,
Given that Yun has been hardly released, in the meantime, we can run our tests in our own hosts, but I believe, it would be great if Arduino can provide the cloud service in a near future, rather than have to use Amazon EC2 or Google Cloud to host our java sockets. Regards!
