I think you just need to register for the Google cloud and can then use the service as you want it. There is probably an advantage if you upload it directly from a Google VM (no costs for uploading from a Google service/very low latency) but it would surprise me if you have to have a Google VM. I can after all upload files to S3 and googles cloud storage even if I host the application on my hardware.
