Description
In Grid systems, a core resource being shared among geographically-dispersed
communities of users is the storage. For this resource, a standard interface
specification (Storage Resource Management or SRM) was defined and is being evolved
in the context of the Open Grid Forum. By implementing this interface, all storage
resources part of a Grid could be managed in an homogenous fashion. In this work, we
consider the extension of StoRM (STOrage Resource Manager, an implementation of SRM
v2.2) in order to integrate a new type of storage resource: the Amazon Simple Storage
Service (S3). Amazon S3 is a simple Web services interface offering access to the
same highly scalable, reliable, fast, inexpensive data storage infrastructure that
Amazon uses to run its own global network of Web sites. By performing this
integration, we offer to the Grid community the capability to manage and access an
incredible amount of storage resources freeing them from considering the costs
associated with server maintenance, or whether they have enough storage available.
The characteristics of StoRM are suitable for a smooth integration with Amazon S3. In
particular, StoRM is designed to be easily adapted to the underlying storage resource
via a plug-in mechanism, therefore a new plugin for integration with the Amazon S3
Web Service will be written. As regards the access policies, StoRM translates the
Grid authorization rules into the Amazon S3 ones and applies them to the Amazon Web
Services identity.
