There are a variety of other players in this cloud storage market. Nirvanix, for example, is a cloud storage vendor that offers storage in three flavors: public, hybrid and private. Its public cloud service, which is hosted by the company in its data centers, can be accessed directly by end users, or resold through reseller agreements with vendors. A hybrid model includes an on-premise box that is supported for increased capacity with the public cloud, while the private edition sits all on the customer's site. "Customers really like this idea of flexible provisioning, delivering on-demand services on a per-GB per month pricing model," says Dru Borden, CEO of Nirvanix.
NetApp is another vendor that offers a variety of on-premise appliances. That company has been touting its relationship with Amazon Web Services, to allow connectivity between an on-premise NetApp system with AWS's public cloud.
Then there are a range of other cloud storage gateway providers, which provide an interface for customers to access public cloud resources for easier on-boarding and management, sometimes including on-premise appliances as well. These vendors include Twin Strata, Panzura, Nasuni StorSimple, Riverbed and others.
