NAS and SAN on AWS


Network Attached Storage (NAS) file level storage. Storage Area Network (SAN) block level storage.  NAS lends itself to quickly provisioning an exported NFS file system or CIFS share to a user backed by a thinly provisioned physical file system. SANs typically use iSCSI.  AWS does not offer native shared / clustered disk that on premise NAS and SAN offerings. Here are some options for running NAS and SAN environments in AWS:

Here is a good session from reInvent in 2013 (keep in mind this information has changed since over a year old) : http://www.slideshare.net/AmazonWebServices/nfs-and-cifs-options-for-aws-stg401-aws-reinvent-2013

Of course, S3 can always be used but this will require changes to the application or use an emulation software (s3fs) to make S3 look like block/file level storage.
