fault tolerance
a general concept that a system has the ability to respond to unexpected failures or system crashed as the backup system immediately and automatically takes over with no loss of service
failover
a specific type of fault tolerance, occurs when a redundant storage server offers an exact replica of 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 resumers operations, taking over from the secondary server

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 curve
charts (1) the cost to the company of the unavailability of information and technology. (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
Details how a company recovers and restores critical business operations and systems after a disaster or extended disruption
business impact analysis
a process that identifies all critical business functions and the effect that a specific disaster may have upon them
emergency notification service
an infrastructure built for notifying people in the 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
incident
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 correected
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
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
means that people with disabilities including visual, auditory, physical, speech, cognitive and neurological can use the web
web accessibility initiative
bring together people from industry, disability organization, government and research labs from around the world to develop guidelines and resources to help make the web accessible to people with disabilities including auditory, cognitive, neurological, physical, speech and visual disabilities.
availability
refers to the time frames when the system is operational
unavailable
when a system is not operating or cannot be used
high availability
occurs when a system is continuously operational at al times
maintainability
reders 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 system
reliability
ensures a system is functioning correctly and providing accurate information
vulnerability
a system weakness that can be exploited by a threat; for example, a password that is never changed or a system left on while an employee goes to lunch
scalability
describes how well a system can scale up or adapt to the increased demands of growth
performance
measure how quickly a system performs a process or transaction
capacity
represents the maximum throughput a system can deliver; for example the capacity of a hard drive represents the size or volume
capacity planning
determines future environmental infrastructure requirements to ensure high quality system performance
usability
the degree to which a system is easy to learn and efficient and satisfying to use
serviceability
how quickly a third party or vendor can change a system to ensure it meets users needs and the terms of any congrats including agreed levels of reliability maintainability and availability.
Moore’s law
refers to the computer chip performance per dollar doubling every 18 months
sustainable or green
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
clean computing
a subset of sustainable MIS, refers to the environmentally responsible use, manufacture, and disposal of technology products and computer equipment
green personal computer
built using environment friendly materials and designed to save energy
ewaste
refers to discarded, obsolete or broken electronic devices
upcycle
reuses or refurbishes ewaste and creates a new product
sustainable MIS disposal
refers to the safe disposal of mis assets at the end of their life cycle
energy consumption
the amount of energy consumed by a business process and system
carbon emission
includes the carbon dioxide and carbon monoxide in the atmosphere, produces by business process and system
grid computing
a collection of computer often geographically dispersed that are coordinated to solve common problems
smart grid
delivers electricity using two way digital technology
virtualization
creates multiple “virtual” machines on a single computing device
storage virtualization
combines multiple network storage devices so they appear to be a single storage device
network virtualization
combines network by spelling the available bandwidth into independent channels that can be assigned in real time to a specific device
server virtualization
combines the physical resources, such as servers, processors, and operating system, from the applications
system virtualization
the ability to present the resource of a single computer as if it is a collection of separate computes, each with its own CPU, network interfaces, storage and operating system
data center
a facility used to house management information system and associated components, such a telecommunications and storage system
cloud computing
stores, manages, and processes data and applications over the internet rather than on a personal computer or server
multi tenancy
a single instance of a system serves multiple customers
single tenancy
each customer or tenant must purchase and maintain and individual system
cloud fabric
the software that makes the benefit of clouds computing possible, such as multiple tenancy
cloud fabric controller
an individual who monitors and provisions cloud resource similar to a server administrator at an individual company
public cloud
promotes massive, global, industrywide applications offered to the general public
private cloud
serves only one customer or organization and can be located on the customers premises or off the customers premises
community cloud
serves a specific community with common business models, security requirements, and compliance consideration
hybrid cloud
includes two or more private, public, or community clouds but each cloud remains separate and is only linked by technology that enable data and application protability
cloud bursting
when a company uses its own computing infrastructure for normal usage and accesses the cloud when it needs to scale for high/peak load requirements ensuring a sudden spike in usage does not result in poor performance or system crashes
utility computing
offers a pay-per-use revenue model similar to a metered service such as gas or electricity
infrastructure as a service
the delivery of computer hardware capability, including the use of servers, networking and storage as a service
dynamic scaling
means that the mis infrastructure can be automatically scaled up or down based on needed requirements
disaster recovery as a service
