The term “cloud computing” conjures up different meanings and images to different people. For some, it might mean cloud storage, whether it’s music or documents. For others, it might be processing in the cloud (think Amazon EC2 or RackSpace). For others, it is applications.
However “cloud” is defined, the stakes are big. Mighty forces (i.e. IT vendors large and small) are lined up to deliver the cloud.
If one were to look up to the actual clouds in the sky, you could imagine the various players as Norse gods, ready to do battle. Based on its recent pricing announcement, we might think of VMware as Loki, the evil trickster. As he’s gained power, he threatens his subjects.
Open source is the good guy here, the Thor to VMware’s Loki. The open source KVM hypervisor is gaining strength. The formation of the Open Virtualization Alliance provides a communications medium for the players in the KVM ecosystem to extoll the virtues and capabilities of open source to help win the battle of the cloud. The open source hypervisor Xen, has also been a counterbalance to VMware for several years now. And we would be remiss, of course, if we did not mention that our own ConVirt 2.0 is providing a level of virtualization and cloud management heretofore not possible for Xen and KVM.
Other open source storm clouds are threatening VMware. The recent announcement by Citrix that it acquired open source-based Cloud.com is another potential threat to vendor lock-in.
The truth is that cloud computing is no myth. In its many forms, it is real, it is here and it would be most unfortunate for any single player to dominate the cloud with inflexible and predatory pricing.
May you find your Valhalla in the cloud(s) with open source.
