How does openstack compare to Eucalyptus? http://www.eucalyptus.com/

Eucalyptus tries to match Amazon's APIs, and (from hearsay) it doesn't scale well.

Openstack doesn't match Amazon's APIs. Nova (compute) is used by NASA and will be used by Rackspace Cloud Servers. Swift (storage) is currently used by Rackspace Cloud Files. Swift (my area of expertise) is production-ready code that is scalable to massive levels (think 100-petabyte clusters and 100000 requests per second).

From http://openstack.org/projects/, most open-source cloud solutions don't scale with the exception of the software behind NASA's Nebula cloud, which as of April was Eucalyptus.
