About Glance
The Image service (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 (VM) 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
