We are a small company with very limit funds. In order to improve our server reliability, we are studying to migrate to CLOUD. We seen some CLOUD provider, they would charge by resources such as, CPU, RAM.....Disk space....High Availability....etc. We have server team, so we also consider to built the private CLOUD, we seen the Windows 8 server, it does need license fee. So we looking at Linux side, we look at Ubuntu and OpenStack. What is the different between Ubuntu and OpenStack solutions? Is it both free on software license? and only to pay the technical support.

What ubuntu provides for cloud setup is Eucalyptus.
Eucalyptus has extensive AMAZON EC2 API, good to have if you are thinking of setting up Hybrid setup lateron. It also has Web Admin console which lacks in Openstack. Openstack is opensource spinoff from RackSpace.
