The first cloud server was ..... the mainframe?
This reminds me of the time I told an Amazon exec., "In the cloud, we're trying to solve with commodity components the problems the IBM mainframe solved a long time ago." The response, a look of disbelief followed by: "I never would have thought of it that way."

Re: mainframe
Here is what I wrote a couple of years ago:



Cloud computing is a new style of computing, and in particular a style of computer deployment that differs from racking and stacking lots of x86 servers in company data centers. From a business and management perspective this difference signifies a return of some of the characteristics of mainframe computing, in terms of power, expense, and centralization of operations and expertise.

Mainframe belittlers, beware the Ides of March
Yes, I think JTemple is right. z cores are not Power cores, and original IFLs are based on specially configured z cores to run Linux. Stewart Alsop II at InfoWorld predicted in 1991 that the last mainframe would be unplugged by an InforWorld reader on March 15, 1996. It was a great prediction, given the fact he represented a publication that was drunk on the PC. I once responded on a panel, "Yes, and he'll be fired by a ComputerWorld reader," my employer at the time. What is it about the Ides of March that brings out the aggression in people?

Yes it can.
There is nothing about "Cloud" that dictates a platform.   Z can rock in the cloud because it is a high capacity machine, which is exactly what you want from multi tenant cloud, particularly if there are many small tenants.  Since the machine runs LInux and Java there is very little standing in the way of implementing solutions in a z Cloud.  The larger the number of tenants the better it gets.   On the other hand if your cloud consists of a few very larger throughput oriented guests then a high throughput but medium capacity machine like Power will do better. 

Also, I think you will find that IFLs are specially configured  z cores rather than power cores as stated in the article.  Power makes IFLs now, too.  But they are not the same as z IFLs.

Contact me at  or linkedin if you want to discuss the technical rationale behind what I am saying.

The mainframe is dead, "Long live the mainframe".  This confirms what I have thought for some time. There is a lot of irony here.  (not to mention Big Iron)

IT technology changes at blazing rates but here is a case where the more things change, the more they are the same.  VM is a genius design for a bullet proof platform.
