Private Cloud and Server Virtualization, What's the Difference?
Last week I was sitting at the Louisville VMUG listening to some vendors speak. Even when he was gauging the crowd, he asked the question "what type of cloud is everyone running today?" Everyone responded with the same answer "Private Cloud". That got me fired up enough to send out this tweet that read "I want to express this very important point. Server Virtualization != Private Cloud"
Of course, everyone is going to have their own opinions on this topic because the term "cloud" is always open for debate. Let me give you a take on what I think. I've had this conversation with Chris Colotti and some other folks a few times so I would consider myself somewhat educated on the topic.
Server virtualization (or a virtualized datacenter) is what we have been doing for years now. Get a couple of servers, some switches, a storage array, make it all talk, then use VMware Converter or PlateSpin to do some P2Vs. Consolidation, simplifying DR efforts, simplifying administration, and achieving a lower TCO are the main goals of server virtualization. At the heart of all this was running a multitude of virtualized operatiing systems on a hypervisor that virtualized the underlying hardware. Pretty fascinating stuff. Is that cloud? Of course not. It's just a cool technology.
