2 Chapter 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. 4. Identify the environmental impacts associated with MIS. 5. Explain the three components of a sustainable MIS infrastructures along with their business benefits. CHAPTER 5: LEARNING OUTCOMES

3 Chapter THE BUSINESS BENEFITS OF A SOLID MIS INFRASTRUCTURE MIS InfrastructureIncludes the plans for how a firm will build, deploy, use, and share its data, processes, and MIS assets Hardware Software Network Client Server Enterprise ArchitectIs a person grounded in technology, fluent in business, and able to provide the important bridge between MIS and the business

4 Chapter Backup and Recovery Plan BackupAn exact copy of a systems information RecoveryThe 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

5 Chapter SUPPORTING OPERATIONS: INFORMATION MIS INFRASTRUCTURE Disaster Recovery Plan Hot SiteA separate and fully equipped facility where the company can move immediately after a disaster and resume business Cold SiteA separate facility that does not have any computer equipment, but is a place where employees can move after a disaster Warm SiteA separate facility with computer equipment that requires installation and configuration

6 Chapter Disaster Recovery Plan Disaster Recovery PlanA 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 CurveCharts (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 SUPPORTING OPERATIONS: INFORMATION MIS INFRASTRUCTURE

7 Chapter 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 ServiceAn infrastructure built for notifying people in the event of an emergency SUPPORTING OPERATIONS: INFORMATION MIS INFRASTRUCTURE

8 Chapter SUPPORTING CHANGE: AGILE MIS INFRASTRUCTURE AccessibilityRefers to the varying levels that define what a user can access, view, or perform when operating a system Administrator AccessUnrestricted access to the entire system. AvailabilityTime frames when the system is operational UnavailableTime frames when a system is not operating and cannot be used High availabilitySystem is continuously operational at all times MaintainabilityHow quickly a system can transform to support environmental changes

9 Chapter SUPPORTING CHANGE: AGILE MIS INFRASTRUCTURE PortabilityThe ability of an application to operate on different devices or software platforms ReliabilityEnsures a system is functioning correctly and providing accurate information ScalabilityHow well a system can scale up, or adapt to the increased demands of growth

10 Chapter SUPPORTING CHANGE: AGILE MIS INFRASTRUCTURE PerformanceMeasures how quickly a system performs a process or transaction Capacity planningDetermines future environmental infrastructure requirements to ensure high-quality system performance UsabilityThe degree to which a system is easy to learn and efficient and satisfying to use

11 Chapter Moores LawRefers to how the computer chip performance per dollar doubles every 18 months Sustainable, or Green, MISDescribes the production, management, use, and disposal of technology in a way that minimizes damage to the environment Corporate Social ResponsibilityCompanies acknowledged responsibility to society MIS AND THE ENVIRONMENT

12 Chapter Increased Electronic Waste EwasteRefers to discarded, obsolete, or broken electronic devices Sustainable MIS DisposalRefers 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

13 Chapter 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

14 Chapter SUPPORTING THE ENVIRONMENT: SUSTAINABLE MIS INFRASTRUCTURE Grid ComputingA collection of computers, often geographically dispersed, that are coordinated to solve a common problem Cloud ComputingRefers 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)

15 Chapter VirtualizationCreates multiple virtual machines on a single computing device Data CenterA 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 SUPPORTING THE ENVIRONMENT: SUSTAINABLE MIS INFRASTRUCTURE
