Gerardo,
You probably already know this, but consider checking with Sandeep Luthra of LTMedical.net above in this thread, whose company I think still hosts AC in the cloud.
Cheers,
Carl Fogel
Hopefully Sandeep will see this and respond. Until that time, I do not think that Sandeep actually hosts on the cloud.
He set up our server, and provides excellent service and support, and does backup for this. But, the actual server is on your site.
