THE BUSINESS BENEFITS OF A SOLID

MIS INFRASTRUCTURE• MIS Infrastructure—Includes the plans for

how a firm will build, deploy, use, and share its data, processes, and MIS assets Hardware Software Network Client Server

• Enterprise Architect—Is a person grounded in technology, fluent in business, and able to provide the important bridge between MIS and the business

• 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

• Companies should choose a backup and recovery strategy in line with their goals and operational needs

SUPPORTING OPERATIONS: INFORMATION MIS INFRASTRUCTURE

Chapter 5

5-5-55

SUPPORTING OPERATIONS: INFORMATION MIS INFRASTRUCTURE

• Disaster 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

Chapter 5

• Disaster 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 info and technology and (2) the cost to the organization of recovering from a disaster over time

• 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

Emergency Notification Service—An infrastructure built for notifying people in the event of an emergency

SUPPORTING OPERATIONS: INFORMATION MIS INFRASTRUCTURE

Chapter 5

5-5-88

SUPPORTING CHANGE: AGILE MIS INFRASTRUCTURE

• Accessibility—Refers to the varying levels that define what a user can access, view, or perform when operating a system 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

Chapter 5

5-5-99

SUPPORTING CHANGE: AGILE MIS INFRASTRUCTURE

• 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

• Scalability—How well a system can scale up, or adapt to the increased demands of growth

Chapter 5

5-5-1010

SUPPORTING CHANGE: AGILE MIS INFRASTRUCTURE

• 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

Chapter 5

5-5-1111

• Moore’s Law—Refers to how 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

Chapter 5

5-5-1212

• 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 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

MIS AND THE ENVIRONMENT

Chapter 5

5-5-1313

MIS AND THE ENVIRONMENT

• Increased Carbon Emissions

The major human-generated greenhouse gases, such as carbon emissions from energy use, are very likely responsible for the increases in climatic temperature over the past half a century

When left on continuously, a single desktop computer and monitor can consume at least 100 watts of power per hour

Chapter 5

5-5-1414

SUPPORTING THE ENVIRONMENT: SUSTAINABLE MIS INFRASTRUCTURE

• Grid Computing—A collection of computers, often geographically dispersed, that are coordinated to solve a common problem

• Cloud Computing—Refers to the use of resources and applications hosted remotely on the Internet

Infrastructure as a Service (IaaS)

Software as a Service (SaaS)

Platform as a Service (PaaS)

Chapter 5

5-5-1515

• Virtualization—Creates multiple “virtual” machines on a single computing device

• 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
