Cloud storage is a model of data storage that stores digital data in
|
|
logical pools and physical storage that spans across multiple servers
|
|
and locations. Cloud storage commonly refers to a hosted object storage
|
|
service, however the term also includes other types of data storage that
|
|
are available as a service, for example block storage.
|
|
|
|
Cloud storage runs on virtualized infrastructure and resembles broader
|
|
cloud computing in terms of accessible interfaces, elasticity,
|
|
scalability, multi-tenancy, and metered resources. You can use cloud
|
|
storage services from an off-premises service or deploy on-premises.
|
|
|
|
Cloud storage consists of many distributed, synonymous resources, which
|
|
are often referred to as integrated storage clouds. Cloud storage is
|
|
highly fault tolerant through redundancy and the distribution of data.
|
|
It is highly durable through the creation of versioned copies, and can
|
|
be consistent with regard to data replicas.
|
|
|
|
At large scale, management of data operations is a resource intensive
|
|
process for an organization. Hierarchical storage management (HSM)
|
|
systems and data grids help annotate and report a baseline data
|
|
valuation to make intelligent decisions and automate data decisions. HSM
|
|
enables automated tiering and movement, as well as orchestration of data
|
|
operations. A data grid is an architecture, or set of services evolving
|
|
technology, that brings together sets of services enabling users to
|
|
manage large data sets.
|
|
|
|
Example applications deployed with cloud storage characteristics:
|
|
|
|
* Active archive, backups and hierarchical storage management.
|
|
|
|
* General content storage and synchronization. An example of this is
|
|
private dropbox.
|
|
|
|
* Data analytics with parallel file systems.
|
|
|
|
* Unstructured data store for services. For example, social media
|
|
back-end storage.
|
|
|
|
* Persistent block storage.
|
|
|
|
* Operating system and application image store.
|
|
|
|
* Media streaming.
|
|
|
|
* Databases.
|
|
|
|
* Content distribution.
|
|
|
|
* Cloud storage peering.
