And CP-40 before that. See http://www.leeandmelindavarian.com/Melinda/neuvm.pdf 
for the real scoop!

There were giants in those days...

VM's roots are in CP-67, which goes back to 1968 or so.

When we think of cloud computing, we think of situations, products and ideas
that started in the 21st century. This is not exactly the whole truth. Cloud
concepts have existed for many years. Here, I will take you back to that
time.

It was a gradual evolution that started in the 1950s with mainframe
computing.

Multiple users were capable of accessing a central computer through dumb
terminals, whose only function was to provide access to the mainframe.
Because of the costs to buy and maintain mainframe computers, it was not
practical for an organization to buy and maintain one for every employee.
Nor did the typical user need the large (at the time) storage capacity and
processing power that a mainframe provided. Providing shared access to a
single resource was the solution that made economical sense for this
sophisticated piece of technology.

After some time, around 1970, the concept of virtual machines (VMs) was
created.

Using virtualization software like VMware, it became possible to execute one
or more operating systems simultaneously in an isolated environment.
Complete computers (virtual) could be executed inside one physical hardware
which in turn can run a completely different operating system.

The VM operating system took the 1950s' shared access mainframe to the next
level, permitting multiple distinct computing environments to reside on one
physical environment. Virtualization came to drive the technology, and was
an important catalyst in the communication and information evolution.

In the 1990s, telecommunications companies started offering virtualized
private network connections.

Historically, telecommunications companies only offered single dedicated
point-to-point data connections. The newly offered virtualized private
network connections had the same service quality as their dedicated services
at a reduced cost. Instead of building out physical infrastructure to allow
for more users to have their own connections, telecommunications companies
were now able to provide users with shared access to the same physical
infrastructure.

The following list briefly explains the evolution of cloud computing:

. Grid computing: Solving large problems with parallel computing

. Utility computing: Offering computing resources as a metered service

. SaaS: Network-based subscriptions to applications

. Cloud computing: Anytime, anywhere access to IT resources delivered
dynamically as a service

Now, let's talk a bit about the present.

http://www.softlayer.com/ is one of the largest global providers of cloud
computing infrastructure.

IBM already has platforms in its portfolio that include private, public and
hybrid cloud solutions. The purchase of SoftLayer guarantees an even more

vice-iaas/ solution. While many companies look to maintain some applications
in data centers, many others are moving to public clouds.

Even now, the purchase of bare metal can be modeled in commercial cloud (for
example, billing by usage or put another way, physical server billing by the
hour). The result of this is that a bare metal server request with all the
resources needed, and nothing more, can be delivered with a matter of hours.

In the end, the story is not finished here. The evolution of cloud computing
has only begun.
