What is Rackspace Private Cloud?

Rackspace offers a tool set that enables users to quickly deploy a private cloud OpenStack cluster configured according to the recommendations of Rackspace OpenStack specialists.

Previous versions of Rackspace Private Cloud were packaged in an ISO that contained a full Ubuntu OS and a Chef server running on a virtual machine. Although the ISO was a convenient and simple package, it did not allow large deployments. The user also had no choice of host operating system and Chef server running on a virtual machine was resource-intensive.

Rackspace Private Cloud v4.0.0 and later can now be deployed with a Chef-based approach that enables users to create an OpenStack cluster on Ubuntu, CentOS, or Red Hat Enterprise Linux. This version uses installation scripts, which creates a more traditional application experience for the Linux system administrator. It also offers a framework that is capable of being updated without downloading and deploying a whole new ISO.
