| Cloud storage is a service model in which data is maintained, managed, backed up remotely and made available to users over a network (typically the Internet).

As of this writing, the most common use cases are cloud backup, disaster recovery and archiving infrequently accessed data. There are three main cloud-based storage architecture models: public, private and hybrid: Public cloud storage services provide a multi-tenant storage environment that is most suited for unstructured data. Data is stored in global data centers with storage data spread across multiple regions or continents. Private cloud, or on-premises, storage services provide a dedicated environment protected behind an organization's firewall. Private clouds are appropriate for users who need customization and more control over their data. Hybrid cloud is a mix of private cloud and third-party public cloud services with orchestration between the platforms for management. The model offers businesses flexibility and more data deployment options.
