Geo Replication in Hybrid Cloud Storage
Hybrid cloud storage uses object storage in the cloud. Data on-premises is uploaded to cloud object storage until it is accessed again. Many people have first hand experience using cloud object storage with file sharing apps/sites like Dropbox, SkyDrive, YouSendIt, etc, but cloud object storage it also done very effectively with enterprise-level hybrid cloud storage (HCS) like the Microsoft HCS solution. In this case, a StorSimple CiS system, which is iSCSI-based, integrates with Windows Azure Storage, which is object based.
Obviously, a data translation process turns block data into objects. This happens during a data deduplication process, when incoming data exits the input queue in a CiS system. The deduped block objects in a CiS system are called fingerprints and have object properties such as being content-addressable and immutable. From that point on, block data is managed as objects, whether it is on-premises or in the cloud. In other words, the Microsoft HCS solution is a hybrid object store for block data. There are a lot of benefits to working this way, including:
When you look at solving the most vexing problems in your storage environment, especially data growth, backup data protection and the inability to test DR plans, the benefits of a hybrid object storage architecture are indeed powerful.
