The IaaS Rush

The IaaS Rush
Why is everybody getting into the IaaS business? For a long time, it was only Amazon, then Rackspace, Savvis etc followed but there were no new significant players for a long time. However, most recently, IaaS has been really hot; the new entrants into this space are Google, Microsoft and HP. While Amazon, Rackspace, Savvis have predominantly been operating in the IaaS space, Google was more of a PaaS and SaaS player. It did a little bit on the IaaS side with Google drive but nothing to the extent of Amazon S3. Microsoft was also a platform player with Azure, but recently introduced an IaaS offering into Azure. For HP, it was a brand new entry into the Cloud Space. While I am not sure about what technology Google is using to power its IaaS (should most probably be something based on Xen or KVM), HP’s IaaS management layer is run on OpenStack with probably Xen as the Virtualization layer.


This week marks the second anniversary of the founding of the OpenStack cloud computing platform, and it will be an occasion for celebration in the open-source community. After all, OpenStack is leading a movement in cloud computing, garnering the label of the "Linux of cloud computing," a reference to the hugely successful open-source operating system.
