2. 5-2 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

3. 5-3 SUPPORTING OPERATIONS: INFORMATION MIS INFRASTRUCTURE  Backup and recovery plan  Disaster recovery plan  Business continuity plan

4. 5-4 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

5. 5-5 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

6. 5-6 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

13. 5-13 CLOUD COMPUTING  Cloud computing - Refers to the use of resources and applications hosted remotely on the Internet

14. 5-14 VIRTUALIZED COMPUTING  Virtualization - Creates multiple “virtual” machines on a single computing device

15. 5-15 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
