hello. is that possible for bitbucket to rely entirely on S3 storage rather than NAS...

[Emmanuel Salzard]

by a way or another....

thank you very much.

Yes, but I wouldn't recommend it.  Bitbucket really likes fast storage and S3 is anything but fast.  

S3 is not normal block type storage. It's essentially an API web service, so you need a special tool in order to mount it like block storage.  Check out the s3-fuse open source project that allows you to mount S3 storage as a block device on linux. There are a few gotchas to mounting S3 as a volume on linux, so if you are really going to do this, I can give you a couple points to watch out for based on my experience.
