There's a trick called "Domain fronting" (ab)using CDN's like that which is useful.

Tor's "meek" pluggable transport uses it, but only supports a couple of cdns as you need to run infra behind the CDN which costs money.

As for Iodine, I used to run a few public DNS tunnel servers with it for people. Its a pain in the ass to get working reliably.
