+summary: "OpenStack Image Registry and Delivery Service"
+description: |
+ The Glance project provides an image registration and discovery service
+ (Parallax) and an image delivery service (Teller). These services are used
+ in conjunction by Nova to deliver images from object stores, such as
+ OpenStack's Swift service, to Nova's compute nodes.
