1 CHAPTER FIVE INFRASTRUCTURES SUSTAINABLE TECHNOLOGIES

2 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

3 SECTION 5.1 MIS Infrastructures

4 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

5 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

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

7 SUPPORTING OPERATIONS: INFORMATION MIS INFRASTRUCTURE
Backup and recovery plan Disaster recovery plan Business continuity plan

8 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

9 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

10 Backup and Recovery Plan

11 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

12 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

13 Business Continuity Plan
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

14 Business Continuity Plan

15 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

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

17 Accessibility 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

18 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

19 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

20 Portability Portability – The ability of an application to operate on different devices or software platforms

21 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 Vulnerability – a system weakness that can be exploited by a threat

22 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

23 Usability 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

24 SECTION 5.2 Building Sustainable MIS Infrastructures

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

26 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

27 MIS AND THE ENVIRONMENT
Three Primary Side Effects Of Businesses’ Expanded Use Of Technology

28 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

29 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

30 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 watts of power per hour

31 SUPPORTING THE ENVIRONMENT: SUSTAINABLE MIS INFRASTRUCTURE
The components of a sustainable MIS infrastructure include

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

33 Virtualized Computing
Virtualization - Creates multiple “virtual” machines on a single computing device

34 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

35 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

36 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

37 Cloud Computing

38 Cloud Computing

39 Cloud Computing
