You are not totally wrong. TestingBot seems to offer their servers as a cloud to their customers. Which means that TestingBot did not move to its own cloud (compare that to the title of the blogpost please), but they moved to their own servers (and build a cloud on them, like you said). Their customer can scale easily, they can not. Their customers don't have to pay for all the hardware needed, they do. Hence they are not using a cloud, they did not move to a cloud - they are using servers, they moved onto their own servers. The title is wrong. Why is that important? Not only because it is a basic misconception, but because saying "we moved to our own cloud" misrepresents their current abilities regarding their ability to scale and their cost structure.
