PayPal is moving its 15,000 nodes off on VMware, the proprietary cloud
platform, to the relatively unstable OpenStack, the anti-Amazon open source
cloud platform backed by IBM, HP, Dell, Red Hat and Rackspace.
If the migration is successful, then eBay, PayPal’s parent company, is likely
to follow suit and move its 65,000 physical nodes to OpenStack, retaining
some sort of VMware reserve if VMware is lucky.
