History dictates future of virtualization
A technology, not a market
Customer Success Testimonial: Recovery is Everything
First, a bit of history. In the early 1970s, IBM had two separate operating system development teams competing for the future of the mainframe. The establishment - represented by MVS - offered continuity from the age of the 360.
Another group of trendy virtual machine enthusiasts were quietly working on VM/370 - an exciting route away from the unwieldy monolith that MVS had become. The VM team even had stylish enamel button badges made with the legend "VM Bigot".
IBM's VM/370 was not the origin of virtualization - that accolade probably belongs to its precursors CP-40 and CP/CMS (interestingly, an early example of open source).
But it was the first commercial manifestation of virtualization and laid the ground for the bulk of development since - right down to VMWare, VirtualLogix, QEMU and a host of others.
Even in the 1970s anyone with any sense could see the advantages virtualization offered. It separates applications and operating systems from the hardware. With VM/370 you could even run MVS on top - along with other operating systems such as Unix. The irony was it took a long time for VM/370 - now called z/VM - to overtake MVS and take its place in IBM's product range. By the time it did, it was largely hidden from view - as such "deep" technology ought to be.
There is a lesson here for the new breed of "VM Bigots" (badge pictured). Virtualization is not a product - it is an enabling technology and as such it should be hidden from view. One wise commentator has already spotted this. Others who see virtualization as something more than a useful technology would do well to learn from history.®

COMMENTS
How about getting the history right?
VM /370 the first commercial manifestation of virtualization? Sounds rather wrong to me, I seem to recall the both Burroughs and ICL had virtual machines well before VM/370 saw the light of day.
Sooner rather than later
And not on the OS level, but on the hardware level with VMware ESX 3i.
An Inconvenient Truth?
"if virtualization is truly a compelling technology, it will "vanish" in a comparably short time. of course, the idea is something of a late bloomer, considering it was first implemented in the Mainframe Age (late Cretaceous? i am old...); still, i think the commentator is right, and technological ubiquity is indeed imminent."
Strange that you don't realise that it "vanished" years ago, so that its Stealth could become ubiquitous and exclusive before the mainstream "discovered" it.
And yes, there is absolutely no doubt that virtualization is truly a compelling technology which is why it will "vanish" for it is the defacto Control parameter for Real scenarios, putting as it does, ITs Leverage into a Virtual Cloud.
From there, IT can do exactly as ITs Controller[s] wishes/wish.
Virtual Untouchables? You can bet your shirt on that Inconvenient Truth if you Realise IT as AI Global Operating Device Sender.
And although you cannot buy it to own it, you can buy into it to exercise ITs Controls for they reach dDeep into every Market.
