Enterprise cloud storage is public storage purchased from a cloud service provider (CSP) for all or most of an organization. Enterprise cloud storage can be contrasted with consumer cloud storage, which is often free or purchased at a low price for an individual user's needs.
Common use cases for enterprise cloud storage are archiving, primary storage of application data, content distribution, backup and disaster recovery. Organizations may turn to an enterprise cloud to solve a number of problems, including high on-premise storage costs, complex management and the need to upgrade on-site infrastructure.
Cloud storage prices vary, depending on how much data is stored, data protection requirements, and sometimes the type of data. Retrieving data from the cloud, for example, can come with added costs. Pricing models differ between providers, so enterprises looking into the cloud may shop around for the cloud host best suited to their needs.
Amazon Simple Storage Service (S3) is for the most popular public e-enterprise storage cloud. Google, Microsoft, HP, IBM and Rackspace also offer public clouds. There are also many smaller providers who maintain their own cloud infrastructure. CSPs vary by offering different prices, connection options, service-level agreements (SLA) and data center locations.
Cloud gateway vendors such as Panzura are also utilized in enterprise cloud storage, providing a familiar interface to the user, caching data locally and encrypting the data. Cloud gateways can also use deduplication and compression to reduce the data footprint and conserve storage capacity.
