That&#x27;s very interesting in hindsight!<p>I don&#x27;t think those so called AWS zombies ever were zombies or made a dent in AWS&#x27; adoption or success, it&#x27;s more like the other way around.<p>He may have been on to something, but I think Jim just wanted to promote his own &quot;open standards&quot; and company.<p>Eucalyptus&#x27; CEO (Mårten Mickos) moved on to HP Cloud (big Openstack deployment) which closed a year after that because they were not competitive.<p>HP currently (try to) also sell Eucalyptus to enteprises precisely because of its AWS compatibility, so they&#x27;re trying to make money off AWS basically.<p>Rackspace is nowadays also managing AWS for customers, so making money off AWS as well.<p>Openstack continues to be the under-used and over-developed darling of all big virt players; at least it appears to be building some standards of sorts so there&#x27;s that.<p>Cloudstack&#x27;s users were never big on AWS, in fact the API compat module was almost deprecated and it&#x27;s now a separate project that gets little attention and usage; along with other 3rd party API implementations.<p>Cloudstack - as well as other private cloud projects out there, are doing just fine, suiting the needs of it&#x27;s users and developers who - shockingly! - do not need or want to use AWS or other public providers, enabling them to run their own infra, whether private or public.<p>My 2 pence.<p>Disclaimer: Cloudstack community member and committer
