  1. CHAPTER OVERVIEW • SECTION 5.1 – MIS INFRASTRUCTURE • The Business Benefits of a Solid MIS Infrastructure • Supporting Operations: Information MIS Infrastructure • Supporting Change: Agile MIS Infrastructure • SECTION 5.2 – BUILDING SUSTAINABLE MIS INFRASTRUCTURES • MIS and the Environment • Supporting the Environment: Sustainable MIS Infrastructure

  2. SECTION 5.1 MIS Infrastructures

  3. LEARNING OUTCOMES • Explain MIS infrastructure and its three primary types • Identify the three primary areas associated with an information MIS infrastructure • Describe the characteristics of an agile MIS infrastructure

  4. 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

  5. THE BUSINESS BENEFITS OF A SOLID MIS INFRASTRUCTURE • Supporting operations • Information MIS infrastructure • Supporting change • Agile MIS Infrastructure • Supporting the environment • Sustainable MIS infrastructure

  6. SUPPORTING OPERATIONS: INFORMATION MIS INFRASTRUCTURE • Backup and recovery plan • Disaster recovery plan • Business continuity plan

  7. 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

  8. 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

  9. Backup and Recovery Plan

  10. 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

  11. 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 services

  12. SUPPORTING CHANGE: AGILE MIS INFRASTRUCTURE • Characteristics of an agile MIS infrastructure • Accessibility • Availability • Maintainability • Portability • Reliability • Scalability • Usability

  13. Accessibility • 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

  14. Availability • 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

  15. Maintainability • 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

  16. Portability • Portability – The ability of an application to operate on different devices or software platforms

  17. Reliability • 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

  18. Scalability • 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

  19. Usability • Usability – The degree to which a system is easy to learn and efficient and satisfying to use

  20. SECTION 5.2 Building Sustainable MIS Infrastructures

  21. LEARNING OUTCOMES • Identify the environmental impacts associated with MIS • Explain the three components of a sustainable MIS infrastructures along with their business benefits

  22. MIS AND THE ENVIRONMENT • 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

  23. MIS AND THE ENVIRONMENT Three Primary Side Effects of Businesses’ Expanded Use of Technology

  24. 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

  25. Increased Energy Consumption • 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

  26. 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

  27. SUPPORTING THE ENVIRONMENT: SUSTAINABLE MIS INFRASTRUCTURE • The components of a sustainable MIS infrastructure include • Grid computing • Cloud computing • Virtualized computing

  28. Grid Computing • Grid computing - A collection of computers, often geographically dispersed, that are coordinated to solve a common problem

  29. Cloud Computing • Cloud computing - Refers to the use of resources and applications hosted remotely on the Internet

  30. Cloud Computing • Infrastructure as a Service (IaaS) • Software as a Service (SaaS) • Platform as a Service (PaaS)

  31. Virtualized Computing • Virtualization - Creates multiple “virtual” machines on a single computing device

  32. 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
