Welcome to Glance's documentation!

The Glance project provides a service where users can upload and discover data assets that are meant to be used with other services. This currently includes images and metadata definitions.

Glance image services include discovering, registering, and retrieving virtual machine images. Glance has a RESTful API that allows querying of VM image metadata as well as retrieval of the actual image.

VM images made available through Glance can be stored in a variety of locations from simple filesystems to object-storage systems like the OpenStack Swift project.

Glance, as with all OpenStack projects, is written with the following design guidelines in mind:

Component based architecture: Quickly add new behaviors
Highly available: Scale to very serious workloads
Fault tolerant: Isolated processes avoid cascading failures
Recoverable: Failures should be easy to diagnose, debug, and rectify
Open standards: Be a reference implementation for a community-driven api

This documentation is generated by the Sphinx toolkit and lives in the source tree. Additional documentation on Glance and other components of OpenStack can be found on the OpenStack wiki.
