<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>
