I noticed that Google Cloud's Storage Transfer Service only works when the sink bucket is Google Cloud, not S3. However, I would like to move files from Google Cloud Storage to Amazon S3, and an alternative I can think of is to spin up an instance on Google Cloud, install the AWS CLI, and then transfer the files that way.
My questions are:
1) Is there a better approach than that?
2) If I did the transfer via the instance, is there a clear way of getting the cost for doing that?
