AWS Elastic File System is go

Amazon Web Services has taken its Elastic File System (EFS) storage service live in three regions after over a year in preview testing.

The EFS system was rolled out as a preview a year ago April, and the firm said it's now live in the US East (Northern Virginia), US West (Oregon), and Europe (Ireland) regions. The service gives AWS users the chance to store files in four types of SAN-style block storage.

"The file system grows and shrinks as necessary (there's no fixed upper limit and you can grow to petabyte scale) and you don't pre-provision storage space or bandwidth," said the company in a statement.

"You pay only for the storage that you use. EFS protects your data by storing copies of your files, directories, links, and metadata in multiple Availability Zones."

The US regions will charge $0.30 per GB per month, with European data costing $0.33 for the same amount and period. ®
