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.
