Hello there. I think the presentation is about hosting Moodle sites "in the cloud" in general (as opposed to in a box in your office) and not specifically about the HQ-managed MoodleCloud package. MoodleCloud from Moodle HQ is already set up for you so you don't need developers or any special tech support. (Note there are certain restrictions that come with that, such as adding new themes or plugins, but on the plus side, you don't need to be an IT specialist to have a MoodleCloud site.)
Thank you. This is reassuring.
