| Cloud storage model | Store digital data in logical pools |
| physical storage | spans multiple servers (sometimes in multiple locations |
| Cloud environment management done by | cloud storage providers |
| Payper use | storage capacity |
| Cloud storage services accessed using | a web service application programming interface (API) / applications that utilize the API |
| applications that utilize the API | cloud desktop storage / cloud storage gateway / Web-based CMS. |
Cloud Storage Benefits
| Payment | Pay for what you use (Total Cost of Ownership). |
| Time to Deployment | It delivers the storage needed very quickly |
| Information Management | It locks down data in support of requirements. |
Cloud Storage Requirements
| Data Security | Security is provided by encryption, permissions and access controls. |
| Durability | Data is stored redundantly in multiple places whenever there is a data loss due to disasters, human error, or mechanical faults data is recovery using the redundant copy. |
| Availability | Data should be available when needed. |
Cloud Storage Working?
Cloud storage uses data servers for storing and sending data to multiple servers using internet. Users uses web-based interface for storing and sending data to multiple servers by manually / automated.
