Virtualization, in spite of its unfortunate naming, is one hot technology beat to follow.
The software has revolutionized the data center and enabled the cloud, not to mention what it has done to (and for) industry economics and software licensing.
I am departing at just the right moment: the debut of new class of cloud application hypervisors for multi-VM apps. Trying to conceptualize all of the pieces running in harmony -- the hypervisors, virtual machines, management and monitoring tools, development tools, the hybrid cloud and public cloud-- is making this lay person downright dizzy.
But I do have a few random thoughts to share, which I hope may amuse those bleary-eyed techies trying to get through the mid-winter morning blues:
Why didn't Microsoft purchase VMware? The NEED was obvious even to the hordes of reporters following the OS beats. Did Microsoft really try to lowball this beauty? It was perhaps the most catastrophic decision for the company ever. I pushed former VMware chief Diane Greene, but she never told me the story.
Why did VMware allow itself to be purchased by EMC? $685 million (and change). Really?
Another acquisition puzzled me: XenSource was practical in trying to make its open source hypervisor hum with Microsoft's ubiquitous software.But why sell to Citrix -- which is, or was, just another arm of Microsoft? The payoff was nice, but Xen execs should have seen that the manuevering could lead to Xen's diminishment, at least by open source backers.
Okay, okay, enough of the Monday morning quarterbacking. Aside from these purported missteps, the level of innovation on this technology front -- from all players -- is staggering. I hope I do retain what knowledge I have, but have a sense that it will be virtually obsolete within six months.
At least I know what the cloud is -- should I be asked at a party or by my five-year-old daughter, who is running a multi-level farming enterprise as part of a game called HayDay on her iPad mini. She may have to move her virtual crops to AWS -- that is if she remembers to water them.
From Wikipedia, there are several implementations but start with the basics : Infrastructure-as-a-Service.
"In the most basic cloud-service model, providers of IaaS offer computers - physical or (more often) virtual machines - and other resources. (A hypervisor, such as Xen or KVM, runs the virtual machines as guests. Pools of hypervisors within the cloud operational support-system can support large numbers of virtual machines and the ability to scale services up and down according to customers' varying requirements.) IaaS clouds often offer additional resources such as images in a virtual-machine image-library ..."
Good luck on the next phase of the not-so-virtual journey. The only clouds I'll be concerned with in the imminent future are those floating over my daughter Abigail (shown above with her pink iPad) and me in the Southern Caribbean in a few weeks time....
