<para>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.</para>
|
|
<para>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.</para>
|
|
<para>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.</para>
|
|
<para>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.</para>
