The glib answer is that a cloud provider understands the need for a private network.
But, in that is a deeper truth: a VPS is a cheaper machine. It becomes "cloud" when you use many machines together. If you're using many machines, you really want intercommunication between those machines to be easy, fast and - yes - reasonably secure.
I lived there for a few months. The structures are extremely sturdy, with some fantastic views from the upper levels. The base of the Gasometers have been cleverly fashioned into a shopping complex, with adjacent cinema and gym. No need to ever venture outside! (Even the underground train station can be reached under cover.)
My apartment overlooked one of the hollow central 'cylinders': not much sunlight reached the interior, and - without net curtains - not much privacy (since neighbors opposite had a clear view across the space).
After seeing a huge crowd queuing in the lobby one evening, I realized the basement was used for rock concerts! And yet, not a sound (or vibration) reached the residential areas above.
Yep top tip, always say it's because I'm moving country, only way not to get passed to the customer retention department and it's usually processed immediately with no hassle.
