===============================
Object Storage service overview
===============================
The OpenStack Object Storage is a multi-tenant object storage system. It
is highly scalable and can manage large amounts of unstructured data at
low cost through a RESTful HTTP API.
It includes the following components:
Proxy servers (swift-proxy-server)
Accepts OpenStack Object Storage API and raw HTTP requests to upload
files, modify metadata, and create containers. It also serves file
or container listings to web browsers. To improve performance, the
proxy server can use an optional cache that is usually deployed with
memcache.
Account servers (swift-account-server)
Manages accounts defined with Object Storage.
Container servers (swift-container-server)
Manages the mapping of containers or folders, within Object Storage.
Object servers (swift-object-server)
Manages actual objects, such as files, on the storage nodes.
Various periodic processes
Performs housekeeping tasks on the large data store. The replication
services ensure consistency and availability through the cluster.
Other periodic processes include auditors, updaters, and reapers.
WSGI middleware
Handles authentication and is usually OpenStack Identity.
swift client
Enables users to submit commands to the REST API through a
command-line client authorized as either a admin user, reseller
user, or swift user.
swift-init
Script that initializes the building of the ring file, takes daemon
names as parameter and offers commands. Documented in
http://docs.openstack.org/developer/swift/admin_guide.html#managing-services.
swift-recon
A cli tool used to retrieve various metrics and telemetry information
about a cluster that has been collected by the swift-recon middleware.
swift-ring-builder
Storage ring build and rebalance utility. Documented in
http://docs.openstack.org/developer/swift/admin_guide.html#managing-the-rings.
