One of the TODO entries was to provide a more comprehensive overview of Object Storage/Swift than was already written. This is a first attempt at making it better. This patch also uncomments a line within the 'admin-guide-cloud' book that doesn't reference the common 'about-object-storage' page like others do. I've reverted this and tested thoroughly, not sure why this was there. In addition, I updated a few other pages where they lacked certain clarity. For example- the 'Getting Started' page provided only a very basic overview of the components and without going into too much detail I added further information. There were also a few English syntax changes throughout some of the other pages. Change-Id: I1952d9e1882fc962320304759110a2ccbc50de82 backport: havana

<title>Introduction to Object Storage</title>
|
|
<para>Object Storage is a robust, highly scalable and
|
|
fault tolerant storage platform for unstructured data
|
|
such as objects. Objects are stored bits, accessed
|
|
through a RESTful, HTTP-based interface. You cannot access
|
|
data at the block or file level. Object Storage is commonly
|
|
used to archive and back up data, with use cases in
|
|
virtual machine image, photo, video and music storage.</para>
|
|
<para>Object Storage provides a high degree of availability, throughput,
|
|
and performance with its scale out architecture. Each object is
|
|
replicated across multiple servers, residing within the
|
|
same data center or across data centers, which mitigates the risk
|
|
of network and hardware failure. In the event of hardware failure,
|
|
Object Storage will automatically copy objects to a new location
|
|
to ensure that there are always three copies available.
|
|
Object Storage is an eventually consistent distributed storage
|
|
platform; it sacrifices consistency for maximum
|
|
availability and partition tolerance. Object Storage enables you to
|
|
create a reliable platform by using commodity hardware and
|
|
inexpensive storage.</para>
