Virtualization An umbrella term
describing how a
computer can enhance
the ability to do work.

Service Can be any kind of software
with a demand for resources

So what about a Service
orientated Cloud approach?

Service A Service B
e.g. Sun Grid Engine Cluster e.g. Globus Toolkit
Resource
assignment
based on
need
Spare Pool
- Public Cloud
Private Cloud

More things which are demanded
(by users e.g. to prevent vendor
lock-in)...

Interoperability ability to let different

Portability ability to move services
and port them as easy
as possible

So Services have a demand for
Resources...Smells like
'Infrastructure as a Service'

“If you think of standardization as
the best that you know today, but
which is to be improved tomorrow; you
get somewhere.”
