I was pleasantly surprised today when a compadre of mine sent along a message from Rich Wolski, a professor in the Computer Science Department at the University of California, Santa Barbara. It turns out that Rich and a group he works with have recently released an open-source (under a FreeBSD-style license) infrastructure for cloud computing on clusters that duplicates the functionality of Amazon's EC2, using the Amazon command-line tools directly.? The system is called
Eucalyptus, and it's available for you to use. What's really surprising is that although this has been demonstrated publicly, it looks like absolutely nobody has written about it.
