I'm pretty happy with Ubiquity's hardware, but if it has anything to do with their cloud based software it's gonna be a hard pass due to the increased security risk. It's a shame too, since cloud based services make device admin so convenient.
I don’t see how cloud services could make anything easier than just sticking a Linux box with their controller in a rack or closet. It’s your own cloud.
Sure you wouldn't have internet, but you would have a local network that would still work, and could still be administered.
