Today’s OpenStack announcement has got the cloud computing community talking, and the response is overwhelmingly positive. That’s not too surprising, though, considering that most cloud-infrastructure solutions to date have been proprietary, incomplete or unproven. However, I have to assume the user base will be pretty high-end (enterprises, governments and providers), because smaller businesses might well prefer cloud-in-a-box or familiar VMware solutions for any internal cloud efforts. And OpenStack itself will receive some open source competition later this year from Yahoo’s forthcoming cloud-platform release.
