A File Storage Service on a Cloud Computing Environment for Digital Libraries	2012-12-12	12	.pdf	application/pdf	4963	265	50	Currently, it is possible to find several examples of public cloud storage, such as Amazon S3 (http://aws.amazon.com/en/s3), RackSpace (http://www.rackspace.com/cloud/public/files), and Google Storage (https://developers.google.com/storage), each of which provide high availability, fault tolerance, and services and administration at low cost. Data availability relates to the replication technique the Amazon infrastructure uses.10 There also are solutions that take advantage of public cloud storage using replication techniques based on RAID, for example Redundant Array of Cloud Storage (RACS), a proxy located between multiple cloud storage providers and customers.11 RACS distributes data in a way that provides an opportunity for clients to tolerate interruptions in a public cloud storage service or when the price for using such services gets too high.	cache/ital-1844.pdf	txt/ital-1844.txt
