Thanks Will, I remember having the discussion with Pierre-Luc on his use of Swift for templates. I was curious about the differences on S3 vs Swift for SS since looking at the CS UI when it comes to setting up an S3 image store... the NFS staging is optional. And this make sense to me if your object storage is fast and accessible locally, why the need for staging/caching. The documentation could mention if it is possible to use S3 secondary and nothing else, starting with if SSVM templates can be uploaded to a bucket. I will certainly ask Syed later today :)
