Description: OpenStack Compute - compute node base
OpenStack is a reliable cloud infrastructure. Its mission is to produce
the ubiquitous cloud computing platform that will meet the needs of public
and private cloud providers regardless of size, by being simple to implement
and massively scalable.
.
OpenStack Compute, codenamed Nova, is a cloud computing fabric controller. In
addition to its "native" API (the OpenStack API), it also supports the Amazon
EC2 API.
.
Nova is intended to be modular and easy to extend and adapt. It supports many
different hypervisors (KVM and Xen to name a few), different database backends
(SQLite, MySQL, and PostgreSQL, for instance), different types of user
databases (LDAP or SQL), etc.
.
This is the package you will install on the nodes that will run your
virtual machines.
