Amazon S3 has a limit of 100 buckets per account: http://docs.aws.amazon.com/AmazonS3/latest/dev/BucketRestrictions.html
Does Google Cloud Storage have any such limits? I cannot find any mention of them... but wanted to know before I made a design decision
There are no limits on the number of buckets you can create in Google Cloud Storage.
Keep in mind, though, that bucket names are a global namespace, so if you create them programmatically, make sure the names won't conflict with others.
There is, however, a rate limit on how quickly you can create buckets. See the Quotas & limits page.
