Eucalyptus
From Consultancy.EdVoncken.NET
EUCALYPTUS is an open-source software infrastructure for implementing "cloud computing" on clusters. The current interface to EUCALYPTUS is compatible with Amazon's EC2 interface.
This makes it interesting for building "Private Clouds", or simply for developing your own AMI's on your laptop ;-)
- Ubuntu 9 Server Edition now comes with Eucalyptus built right in!
