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 that includes restoring the information backup
fault tolerance the ability for a system to respond to unexpected failures or system crashes as the backup system immediately and automatically takes over with no loss of service
failover a type of fault tolerance that occurs when a redundant storage server offers an exact replica of the real-time data, and if the primary server crashes, the users are automatically directed to the secondary server or backup server
failback occurs when the primary machine recovers and resumes operations, taking over from the secondary server
disaster recovery plan a detailed process for recovering information or a system in the event of a catastrophic disaster
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
disaster recovery cost curve charts (1) the cost to the company of the unavailability of information and technology and (2) the cost to the company of recovering from a disaster over time
emergency a sudden, unexpected event requiring immediate action due to potential threat to health and safety, the environment, or property
emergency preparedness ensures a company is ready to respond to an emergency in an organized, timely, and effective manner
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
Disaster Recovery Plan, Business Impact Analysis, Emergency Notification Services, Technology Recovery Strategies Business Continuity Planning Focus Areas
business impact analysis a process that identifies all critical business functions and the effect that a specific disaster may have upon them
emergency notification services an infrastructure built for notifying people int eh event of an emergency
technology failure occurs when the ability of a company to operate is impaired because of a hardware, software, or data outage
incidents unplanned interruption of a service
incident record contains all of the details of an incident
incident management the process responsible for managing how incidents are identified and corrected
technology recovery strategies focus specifically on prioritizing the order for restoring hardware, software, and data across the organization that best meets business recovery requirements
Accessibility, Availability, Maintainability, Portability, Reliability, Scalability, Usability Agile MIS Infrastructures Characteristics
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
web accessibility people with disabilities, including visual, auditory, physical, speech, cognitive, and neurological disabilities, can use the web
web accessibility initiative (WAI) brings together people from industry, disability organizations, government, and research labs from around the world to develop guidelines and resources to help make the web accessible to people with disabilities
availability refers to the time frames when the system is operational
unavailable when a system is not operating and cannot be used
high availability occurs when a system is continuously operational at all times
maintainability / flexibility refers to how quickly a system can transform to support environmental changes
portability refers to the ability of an application to operate on different devices or software platforms, such as different operating systems
reliability / accuracy ensures all systems are functioning correctly and providing accurate information
vulnerability a system weakness that can be exploited by a threat
scalability refers to how well a system can adapt to increased demands
performance measures how quickly a system performs a certain process or transaction
capacity represents the maximum throughput a system can deliver
capacity planning determine the future IT infrastructure requirement for new equipment and additional network capacity
usability the degree to which a system is easy to learn, efficient, and satisfying to use
serviceability how quickly a third party or vendor can change a system to ensure it meets user needs and the terms of any contracts, including agreed levels of reliability, maintainability, or availability
Moore's Law refers to the computer chip performance per dollar doubles every 18 months
sustainable, or "green", MIS describes the manufacture, management, use, and disposal of information technology in a way that minimizes damage to the environment, which is a critical part of a corporation's responsibility
corporate social responsibility companies' acknowledged responsibility to society
increased electronic waste, increase energy consumption, increase carbon emissions Pressures Driving Sustainable MIS Infrastructures
ewaste old computer equipment, does not end up in a landfill, where the toxic substances it contains can leach into groundwater, among other problems
sustainable MIS disposal refers to the safe disposal of IT assets at the end of their life cycle
energy consumption the amount of energy consumed by business processes and systems
carbon emissions includes the carbon dioxide and carbon monoxide in the atmosphere, produced by business processes and systems
Grid Computing, Virtualized Computing, Cloud Computing Sustainable MIS Infrastructure Components
grid computing an aggregation of geographically dispersed computing, storage, and network resources, coordinated to deliver improved performance, higher quality of service, better utilization, and easier access to data
smart grid delivers electricity using two-way digital technology
virtualization protected memory space created by the CPU allowing the computer to create virtual machines
system virtualization the ability to present the resources of a single computer as if it is a collection of separate computers ("virtual machines"), each with its own virtual CPUs, network interfaces, storage, and operating system
data center a facility used to house management information systems and associated components, such as telecommunications and storage systems
cloud computing refers to resources and applications hosted remotely as a shared service over the Internet
multi-tenancy 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 the benefits of cloud computing possible, such as multi-tenancy
cloud fabric controller an individual who monitors and provisions cloud resources, similar to server administrator at an individual company
on-demand self-service, broad network access, multi-tenancy, rapid elasticity, measured service Benefits of Cloud Computing
utility computing offers a pay-per-use revenue model similar to a metered service such as gas or electricity
service oriented architecture (SOA) supports organizational computing needs with utility-based computing concepts; a collection of services that communicate with each other, for example, passing data from one service to another
