Yes, and if you were doing anything with the recently killed (or soon to be) RemoteApp, billing there was a disaster. Absolute horrible disaster. Overbilled to my employer because their websites did not equal to what they quoted us. They also refuse to honor enterprise contract regarding transfer (Internet2 peer). Just horrible terrible bad no good.
And their MQTT service (IoT) pricing is a joke. $50/month for 400k messages a day (!second, typo) with a cap of 4k? Seriously? That's just 4.6 messages a second, WITH a data restriction that MQTT itself doesn't have.
I routinely load pictures with motion to "house/frontdoor/motion/" topic in the form of a jpg. MQTT specifies nothing about said data ~ I could even store a dvd VOB for video in a topic.
And this offering is for a max data of 48GB/month. To put this in perspective, a dialup modem(!) Gets a top speed of 5.2KB/s , which sustained across a 30 day month = 43.2GB
I can (and have!) bought a cheap-shit VPS server and installed Mosquitto on it. I can use MQTT as the spec indicates, including Websockets and storing picture data. And it's more on the price range of $40/year, not $600/yr
