public class S3Storage
extends Object
implements de.iip_ecosphere.platform.deviceMgt.storage.Storage

A S3Storage grants access to the storage through S3. For this purpose it uses an Amazon S3 Client to communicate with the S3 storage. The storage can be set to a fixed prefix, so it is only working with a subset of the bucket.
