SECTION 5.1

MIS Infrastructures

LEARNING OUTCOMES

1 Explain MIS infrastructure and its three

primary types

2 Identify the three primary areas associated

with an information MIS infrastructure

3 Describe the characteristics of an agile MIS

infrastructure

SOLID MIS INFRASTRUCTURE

 MIS infrastructure – Includes the plans for how

a firm will build, deploy, use, and share its data,

processes, and MIS assets

SOLID MIS INFRASTRUCTURE

 Supporting operations

• Information MIS infrastructure

 Supporting change

• Agile MIS Infrastructure

 Supporting the environment

• Sustainable MIS infrastructure

INFORMATION MIS INFRASTRUCTURE

 Backup and recovery plan

 Disaster recovery plan

 Business continuity plan

Backup and Recovery Plan

 Backup – An exact copy of a system’s

information

 Recovery – The ability to get a system up and

running in the event of a system crash or failure

• Fault tolerance

• Failover

• Failback

Backup and Recovery Plan

 Disaster recovery plan - A detailed

process for recovering information or an

IT system in the event of a catastrophic

disaster such as a fire or flood

 Disaster recovery cost curve - Charts

(1) the cost to the organization of the

unavailability of information and

technology and (2) the cost to the

organization of recovering from a

disaster over time

Backup and Recovery Plan

Backup and Recovery Plan

 Hot site - A separate and fully equipped

facility where the company can move

immediately after a disaster and resume

business

 Cold site - A separate facility that does not

have any computer equipment, but is a

place where employees can move after a

disaster

 Warm site – A separate facility with

computer equipment that requires

installation and configuration

Business Continuity Plan

 Business continuity

planning (BCP) - A plan for

how an organization will

recover and restore partially

or completely interrupted

critical function(s) within a

predetermined time after a

disaster or extended

disruption

Business Continuity Plan

Business Continuity Plan

Business Continuity Plan

 Business impact analysis – Identifies all critical business

functions and the effect that a specific disaster may have

upon them

 Technology failure – occurs when the ability of a company to

operate is impaired because of a hardware, software, or data outage

 Incident – Unplanned interruption of a service

 Incident management – the process responsible for

managing how incidents are identified and corrected

 Accessibility - Refers to the varying

levels that define what a user can

access, view, or perform when

operating a system

 Web accessibility – Allows people

with disabilities to use the Web

 Administrator access – Unrestricted

access to the entire system

 Availability – Time frames when the

system is operational

 Unavailable – Time frames when a

system is not operating and cannot be

used

 High availability – System is

continuously operational at all times

 Maintainability – How quickly a system

can transform to support environmental

changes

 Organizations must watch today’s

business, as well as tomorrow’s, when

designing and building systems

 Systems must be flexible enough to

meet all types of business changes

 Portability – The ability of an application to

operate on different devices or software

platforms

 Reliability - Ensures a system is

functioning correctly and providing

accurate information

 Reliability is another term for

accuracy when discussing the

correctness of systems within the

context of efficiency IT metrics

 Vulnerability – a system weakness

that can be exploited by a threat

 Scalability - How well a system can

scale up, or adapt to the increased

demands of growth

 Performance - Measures how quickly a

system performs a process or transaction

 Capacity planning - Determines future

environmental infrastructure

requirements to ensure high-quality

system performance

 Usability – The degree to which a

system is easy to learn and efficient

and satisfying to use

 Serviceability – How quickly a

third-party can change a system to

ensure it meets user needs and the

terms of any contracts, including

agreed levels of reliability,

maintainability, or availability

SECTION 5.2

Building

Sustainable

MIS Infrastructures

LEARNING OUTCOMES

4 Identify the environmental impacts associated

with MIS

5 Explain the three components of a sustainable

MIS infrastructures along with their business

benefits

MIS AND THE ENVIRONMENT

 Moore’s Law - Refers to the computer chip

performance per dollar doubles every 18

months

 Sustainable, or “green,” MIS - Describes

the production, management, use, and

disposal of technology in a way that

minimizes damage to the environment

 Corporate social responsibility -

Companies’ acknowledged

responsibility to society

MIS AND THE ENVIRONMENT

Three Primary Side Effects Of Businesses’

Expanded Use Of Technology

Increased Electronic Waste

 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

Increased Energy Consumption

 Energy consumption – The amount of energy

consumed by business processes and systems

 Huge increases in technology use have greatly

amplified energy consumption

 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

Increased Carbon Emissions

 Carbon emissions – Carbon dioxide and carbon monoxide produced by business processes and systems

 When left on continuously, a single desktop computer and monitor can consume at least

100 watts of power per hour

SUSTAINABLE MIS INFRASTRUCTURE

 The components of a

sustainable MIS

infrastructure include

Grid Computing

 Grid computing - A collection of computers,

often geographically dispersed, that are

coordinated to solve a common problem

Virtualized Computing

 Virtualization - Creates multiple “virtual”

machines on a single computing device

Virtualized Computing

 Data center – A facility used to house

management information systems and

associated components, such as

telecommunications and storage systems

 Sustainable data centers

• Reduces carbon emissions

• Reduces required floor Space

• Chooses Geographic location

Cloud Computing

 Cloud computing - A model for enabling ubiquitous,

convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal

management effort or service provider interaction

Cloud Computing

 Multi-tenancy – The cloud means that a single

instance of a system serves multiple customers

 Single-tenancy – Each customer or tenant must

purchase and maintain an individual system

 Cloud fabric – The software that makes possible

the benefits of cloud computing, such as

multi-tenancy
