Nova is the first computing engine behind OpenStack. it is a “fabric controller,” which is used for deploying and managing a large number of virtual machines and other instances to handle computing tasks.
Swift could also be a storage system for objects and files. Developers can ask a singular identifier concerning the file or piece of knowledge and let OpenStack decide where to store this information.
It may be a block storage component, which is more analogous to the traditional notion of a computer having the power to access specific locations on a disk drive.
It provides networking capability for OpenStack. It helps to form sure that each one among the components of an OpenStack deployment can communicate with one another quickly and efficiently.
It is that the dashboard behind OpenStack. it’s the only graphical interface to OpenStack. The dashboard provides system administrators a look at what’s happening within the cloud, and manage it.
It provides image services to OpenStack. during this case, “images” refers to pictures (or virtual copies) of hard disks. Glance allows these images to used as templates when deploying new virtual machine instances.
It provides telemetry services, which enable the cloud to provide billing services to individual users of the cloud. It also keeps a verifiable count of each user’s system usage of each one among the numerous components of an OpenStack cloud.
