Introduction
|
|
|
|
|
------------
|
|
|
|
|
|
|
|
|
|
Nova is the software that controls your Infrastructure as as Service (IaaS)
|
|
|
|
|
cloud computing platform. It is similar in scope to Amazon EC2 and Rackspace
|
|
|
|
|
CloudServers. Nova does not include any virtualization software, rather it
|
|
|
|
|
defines drivers that interact with underlying virtualization mechanisms that
|
|
|
|
|
run on your host operating system, and exposes functionality over a web API.
|
|
|
|
|
|
|
|
|
|
This document does not attempt to explain fundamental concepts of cloud
|
|
|
|
|
computing, IaaS, virtualization, or other related technologies. Instead, it
|
|
|
|
|
focues on describing how Nova's implementation of those concepts is achieved.

This page outlines concepts that you will need to understand as a user or
|
|
|
|
|
administrator of an OpenStack installation. Each section links to more more
|
|
|
|
|
detailed information in the `Administration Guide`_, but you'll probably want
|
|
|
|
|
to read this section straight-through before tackling the specifics presented
|
|
|
|
|
in the administration guide.
