Move the introductory sections one level up, removing the separate section for them. This reads much nicer in HTML now. There's also no need to name the first paragraphs of a chapter "Introduction", this is implied. Change-Id: Ife4275807561dae2ca57dc71b7602240efa94663

<para>Cloud storage is a model of data storage where digital data
|
|
is stored 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
|
|
has extended to include other types of data storage that are
|
|
available as a service, for example block storage.</para>
|
|
<para>Cloud storage is based on virtualized infrastructure and
|
|
resembles broader cloud computing in terms of accessible
|
|
interfaces, elasticity, scalability, multi-tenancy, and
|
|
metered resources. Cloud storage services can be utilized from
|
|
an off-premises service or deployed on-premises.</para>
|
|
<para>Cloud storage is made up of many distributed, yet still
|
|
synonymous resources, and is 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 a certain scale, management of data operations can become
|
|
a resource intensive process to an organization. Hierarchical
|
|
storage management (HSM) systems and data grids can help
|
|
annotate and report a baseline data valuation to make
|
|
intelligent decisions and automate data decisions. HSM allows
|
|
for automating 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 allowing users to manage large data sets.</para>
|
|
<para>Examples of applications that can be deployed with cloud
|
|
storage characteristics are:</para>
