We used Azure SQL for our RDBMS requirements, and blob/table storage for our NoSQL stuff. Sure there's a server behind it, but it's transparent to us and it's geo-redundant and replicated. When i say "no servers" what I mean is, we don't need any system admins and very little ops folks. In fact at the moment, devs are pretty much ops since we need very little of it.

I also forgot to mention we have a build server, but thats just a virtual machine that we backup regularly. It's our only piece of static infrastructure. Everything else, except storage which is, again, transparent to us, is destroyed on a weekly, if not daily, basis for new releases.
