Glance is primarily associated with which function in an OpenStack environment?

Glance is primarily associated with the image service in an OpenStack environment. It is responsible for the discovery, registration, and delivery of disk images for virtual machines. Glance enables users to upload and store virtual machine images and retrieve those images for use by the compute service, Nova. This functionality is crucial for deploying and managing virtual machines, as it allows for a consistent and accessible repository of images that can be utilized in different computing instances.

Other functions like network configuration, compute resource allocation, and storage management are handled by different components of OpenStack, such as Neutron for networking, Nova for compute, and Cinder for block storage. Therefore, the role of Glance is distinctly focused on managing images rather than performing these other functions.
