Compute
OpenStack Compute is a compute service that provides server capacity in the cloud. Compute Servers come in different flavors of memory, disk space, and CPU, and can be provisioned in minutes. Interactions with Compute Servers can occur programmatically via the OpenStack Compute API or the Dashboard.
Nova
Project name for the Compute service that provisions and manages large networks of virtual machines, creating a redundant and scalable cloud computing platform.
Swift
Project name for the Object Storage software that creates redundant, scalable object storage using clusters of standardized servers to store petabytes of accessible data. Swift is used as an inexpensive bulk storage system for programmatic object storage.
Glance
Project name for the Image Service software, which is the main image repository piece of OpenStack, it is the place where you will be uploading your images as well as the place from which they will be consumed by the rest of the OpenStack system.
Keystone
Project name for the Identity service software, which offers an integrated identity management system for OpenStack. Initially using token-based authentication, but eventually supporting plug-in modules for identity storage (LDAP, DB, file, PAM, Active Directory, etc...), protocols (SAML, OAUTH, OpenID, etc...)
Server
A server is a virtual machine instance in the compute system. Flavor and image are requisite elements when creating a server.
Flavor
Flavor is an available hardware configuration for a server. Each flavor has a unique combination of disk space, memory capacity and priority for CPU time.
Image
Images are your templates for creating new VMs. The project under OpenStack that stores the available images is called Glance.
Rabbit MQ
Provides robust messaging for applications. It is completely open source and based on open standard protocols.
MySQL
Datastore that stores build-time and run-time state for a cloud infrastructure.
Swift Storage Node
The node that runs Account, Container, and Object services.
Swift Proxy Node
The Swift node that runs Proxy services and accepts incoming API requests.
Swift Ring
The Swift Ring is a set of mappings of OpenStack Object Storage data to physical devices.
Keypairs
These are simple ssh keys and are your credentials for accessing any running instances. Keypairs are added and managed using the Keypairs section of the user dashboard.
Security Groups
Security groups at this time exist mostly as tags for the servers and can be consumed via the meta-data API via a simple curl command. Security groups can be specified as part of the "personality" of an instance.
