It's no secret that the list of companies backing the OpenStack cloud computing platform is growing mighty long. In fact, most analysts agree that that list has to be whittled down over time. But if you think you have a handle on which companies are the top contributors to OpenStack, you may find some surprises.
OpenStack has a brand new top contributor: Hewlett-Packard, which has pledged to put $1 billion behind its cloud computing efforts and just purchased open source cloud computing firm Eucalyptus Systems. According to the folks at Stackalytics.com, which folows the companies that contribution code to OpenStack, HP has overtaken Red Hat as top contributor.
