di6erent cities. The ASP itself contracts with a cycle provider for additional
"oomph" during particularly demanding scenarios, requiring of course that
cycles meet desired security and performance requirements.
An industrial consortium formed to develop a feasibility study for a
next-generation supersonic aircraft undertakes a highly accurate
multidisciplinary simulation of the entire aircraft. This simulation
integrates proprietary software components developed by different
participants, with each component operating on that participant’s
computers and having access to appropriate design databases and other
data made available to the consortium by its members.
A crisis management team responds to a chemical spill by using local
weather and soil models to estimate the spread of the spill, determining
the impact based on population location as well as geographic features
such as rivers and water supplies, creating a shortterm mitigation plan
(perhaps based on chemical reaction models), and tasking emergency
response personnel by planning and coordinating evacuation, notifying
hospitals, and so forth.
Thousands of physicists at hundreds of laboratories and universities
worldwide come together to design, create, operate, and analyze the
products of a major detector at CERN, the European high energy physics
laboratory. During the analysis phase, they pool their computing, storage,
and networking resources to create a "Data Grid" capable of analyzing
petabytes of data.
CLASSROOM EXERCISE
Intel and Apple
Ask your students if they use an Intel based Apple (Macintosh). If they raise
their hands, they have the ability to use virtualization. Parallels Desktop and
VMware Fusion make it possible to run Windows and other PC-based
operating systems on a Mac. Until the release of Mac OS X 10.5 Leopard
Server, Apple's software license agreement explicitly forbade running
multiple copies of Mac OS X Server on a single Mac, preventing Parallels and
VMware from including Mac OS X Server among the operating systems that
could be virtualized legally.
CLASSROOM EXERCISE
Understanding SOA
Tell your students to imagine for a moment that they have a goal to get from
their house in Cleveland, Ohio, to a hotel in Denver, Colorado. How might
they accomplish this?
A few responses might be… You will drive in your car to o6-site parking near
an airport. You’ll park your car and ride a shuttle bus to the airport where (if
you successfully get through security) you board an airplane for Denver.
When you get o6, you walk to the taxi stand and take a taxi to the hotel.
