SECTION 5.2

BUILDING SUSTAINABLE MIS

INFRASTRUCTURES

The section emphasizes the need to keep business systems up-and-running

24x7x365 while continuing to be exible, scalable, reliable, and available is

no easy task. Organizations today must continually watch new architecture

trends to ensure they can keep up with new and disruptive technologies.

LEARNING OUTCOMES

Learning Outcome 5.4: Identify the environmental impacts

associated with MIS.

Increased energy consumption, increased electronic waste, and increased

carbon emissions are all associated with MIS. Ewaste refers to discarded,

obsolete, or broken electronic devices. Sustainable MIS disposal refers to the

safe disposal of MIS assets at the end of their life cycle.

Learning Outcome 5.5: Explain the three components of a

sustainable MIS infrastructure along with their business benefit.

The components of a sustainable MIS infrastructure include:

Grid computing: A collection of computers, often geographically

dispersed, that are coordinated to solve a common problem.

Cloud computing: The use of resources and applications hosted remotely

on the Internet. The term comes (at least in part) from the image of a

cloud to represent the Internet or some large networked environment.

Virtualized computing: The creation of multiple “virtual” machines on a

single computing device.

CLASSROOM OPENER

Grid Computing

Discuss some real-world examples of grid applications (not mentioned in the

book):

A company needing to reach a decision on the placement of a new factory

invokes a sophisticated financial forecasting model from an Application

Service Provider (ASP), providing the ASP with access to appropriate

proprietary historical data from a corporate database on storage systems

operated by a Storage Service Provider (SSP). During the decision-making

meeting, what-if scenarios are run collaboratively and interactively, even

though the division heads participating in the decision are located in

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.

Each of these modes of transportation — car, the shuttle bus, the airplane,

and the taxi — came together as you needed them. Or, said another way,

when you set out from your home in Cleveland, you had not specified the

entire transportation network from exactly which shuttle bus you would take

to exactly which taxi you would use. In addition, at the intersection of each of

these transportation modes — where one mode stopped and you were not

yet at your goal — there is likely more than one option you can use that will

take you a step closer to your destination. For example, you could have

started from your house with a walk to a light rail station that took you

directly into the airport terminal, thus eliminating the car ride and the shuttle

bus.

In this analogy, one could call the transportation modes “services.” A service

can be defined as “the capability to perform work for another, the

speci4cation of the work offered for another, and the offer to perform work

for another.” The car, airplane, bus, taxi, and light rail are all services used

to reach the end goal.

Here is an excellent short video that you can use to support the analogy

above.

CLASSROOM EXERCISE

Ray Kurzweil Video: How Technology’s Accelerating Power

will Transform Us

Proli4c inventor and outrageous visionary Ray Kurzweil explains in abundant,

grounded detail why -- by the 2020s -- we will have reverse-engineered the

human brain, and nanobots will be operating your consciousness. Kurzweil

draws on years of research to show the speed at which technology is

evolving, and projects forward into an almost unthinkable future to outline

the ways we'll use technology to augment our own capabilities, forever

blurring the lines between human and machine.

CLASSROOM EXERCISE

One Laptop Per Child

Nicholas Negroponte lays out the details of his nonpro4t One Laptop Per

Child project. Speaking just days after relinquishing his post as director of the

MIT Media Lab, he announces that he'll pursue this venture for the rest of his

life. He takes us inside the strategy for building the "$100 laptop," and

explains why and how the project plans to launch "at scale," with millions of

units distributed in the first seven countries. "This is not a laptop project; it's

an education project," he says.

Making Movies that Change

Je6 Skoll made his fortune as the first president of eBay. Now he's spending it

at the movies. His company, Participant Productions, makes entertaining,

issues-driven 4lms that inspire real change -- Murderball, Syriana, An

Inconvenient Truth ... Here, he talks about the people who've inspired him to

do good, and about some upcoming 4lms that will open your eyes.
