Sustainable MIS infrastructure
- supports sustainability
Grid computing
Cloud computing
Virtualization
Backup
An exact copy of a systems information
Recovery
The ability to get a system or systems up and running in the event of a system crash or failure
- fail back
- failover
- fault tolerance
Hot site
A separate and fully equipped facility where the company can move immediately after a disaster and resume business
Cold site
A delegate facility that does not have any computer equipment, but is a place where employees can move after a disaster
Warm site
A delegate facility with computer equipment that requires installation and configuration
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 the cost to the organization of the un availability of info and technology and the cost to the organization of recovering from a disaster over time
Business continuity planning
A plan for how an organization will recover and restore partially or completely interrupted critical function 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
Emergency
A sudden unexpected event requiring immediate action
Emergency preparedness
Ensures a company is ready to respond to an emergency in an organized, timely, and effective manner
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 (similar to authorization)
Availability
Time frames when the system is operational
- unavailable
- high availability
Maintainability
How quickly a system can transform to support environmental 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
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, efficient and satisfying to use
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 the community society
E waste
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
Increased carbon emissions
The major human generated greenhouse gases, such as carbon emissions from energy use, are very likely responsible for the changes in global climate
- when left on continuously, a single desktop can consume 100 watts of power per hour
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
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
MIS infrastructure
Includes the plans for how a firm will build, deploy, use, share, and refresh its data, processes, and MIS assets
- hardware
- software
- networks
- clients
- servers
