MIS AND THE ENVIRONMENT
 The general trend in MIS is toward smaller, faster, and
cheaper devices.
 Gordon Moore: that continued advances in technological
innovation made it possible to reduce the size of a
computer chip (the brains of a computer, or even a cell
phone now) while doubling its capacity every two years
Three Primary Side Effects Of Businesses’
Expanded Use Of Technology
E-waste: Refers to discarded, obsolete or
broken electronic devices
E-waste includes CDs, DVDs, thumb drives,
printer cartridges, cell phones, iPods,
external hard drives, TVs, VCRs, DVD
players, microwaves, and so on
Three Primary Side Effects Of Businesses’
Expanded Use Of Technology
The energy
consumed by a
computer is
estimated to
produce as much as
10 percent of the
amount of carbon
dioxide produced by
an automobile
Three primary areas where enterprise
architects focus while maintaining a firm’s MIS
Infrastructure.
SUPPORTING THE ENVIRONMENT:
SUSTAINABLE MIS INFRASTRUCTURE

The components of a
sustainable MIS
infrastructure include
1) Grow in computing
power
2) Become less dependent
on hardware and energy
consumption.
Grid Computing

Grid computing - A collection of computers,
often geographically dispersed, that are
coordinated to solve a common problem
 Computers typically use less than 25
percent of their processing power,
leaving more than 75 percent
available for other tasks.
 Innovatively, grid computing takes advantage of this
unused processing power by linking thousands of
individual computers around the world to create a
“virtual supercomputer” that can process intensive
tasks

Virtualized Computing
Video #8: Virtualization

Virtualization - Creates multiple “virtual” machines on a single
computing device
 Through the use of virtualization, computers can run
multiple operating systems along with multiple software
applications—all at the same time.
By increasing energy efficiency by requiring less hardware to run multiple systems or
applications.
By increasing hardware usability by running multiple operating systems on a single
computer.
Cloud Computing
Stores, manages, and processes data and applications over
the Internet rather than on a personal computer or server.
To these individual users, the cloud appears as their personal
application, device, or document
It is like storing all of your software and
documents “in the cloud,” and all you need is a
device to access the cloud.
No more hard drives, software, or
The best part is that even if your
processing power—that is all located
in the cloud, transparent to the users. machine crashes, is lost, or is stolen,
the information hosted in the cloud is
safe and always available.
Cloud Computing
With cloud computing, an individual or business pays only for the
services they need, when they need them and where, much as we use
and pay for electricity.
In the past, a company would have to pay millions of
dollars for the hardware, software, and networking
equipment required to implement a large system such as
payroll or sales management.
A cloud computing user can simply access the cloud and request a single license
to a payroll application. The user does not have to incur any hardware,
software, or networking expenses.
As the business grows and the user requires more
pay-per-use revenue
employees to have access to the system, the
model similar to a
business simply purchases additional licenses.
metered service such as
