MIS 180 Chapter 5

Chief information officers (CIO)-Backup & Recovery Plan

should have enough confidence in their backup and recovery systems that they could walk around and randomly pull out cables to prove that the systems are safe. The CIO should also be secure enough to perform this test during peak business hours.

Incident Management

the process responsible for managing how incidents are identified and corrected

Grid Computing

A collection of computers, often geographically dispersed, that are coordinated to solve a common problem

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

Infrastructure as a Service

A service that delivers hardware networking capabilities, including the use of servers, networking, and storage over the cloud using a pay-per-use revenue model.

Failover-Backup & Recovery Plan

A specific type of fault tolerance, 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.

Characteristics of an Agile MIS Infrastructure

Accessibility, Availability, Maintainability, Portability, Reliability, Scalability, Usability

Backup

An exact copy of a system's information

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

Hardware

Consists of the physical devices associated with a computer system

Virtualized Computing

Creates multiple "virtual" machines on a single computing device

Smart Grid

Delivers electricity using two-way digital technology

Single-Tenancy

Each customer or tenant must purchase and maintain an individual system

Reliability

Ensures a system is functioning correctly and providing accurate information

Failback-Backup & Recovery Plan

Occurs when the primary machine recovers and resumes operations taking over from the secondary server.

Accesibility

Refers to the varying levels that define what a user can access, view, or perform when operating a system

Software

The set of instructions the hardware executes to carry out specific tasks

Cloud Frabic

The software that makes possible the benefits of cloud computing, such as multi-tenancy

Availability

Time frames when the system is operational

Incident

Unplanned interruption of a service

Technology Failure

occurs when the ability of a company to operate is impaired because of a hardware, software, or data outage

Hot Site

A separate and fully equipped facility where the company can move immediately after a disaster and resume business

Network

A communications system created by linking two or more devices and establishing a standard methodology in which they can communicate

Server

A computer dedicated to providing information in response to requests.

Client

A computer designed to request information from a server

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

Data Center

A facility used to house management information systems and associated components, such as telecommunications and storage systems

Fault tolerance-Backup & Recovery Plan

A general concept that a system has the ability to respond to unexpected failures or system crashes as the backup system immediately and automatically takes over with no loss of service.

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

Enterprise Architect

A person grounded in technology, fluent in business, and able to provide the important bridge between MIS and the business

Business Continuity Plan

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

Maintainability

How quickly a system can transform to support environmental changes

Scalability

How well a system can scale up, or adapt to the increased demands of growth

Business Impact Analysis

Identifies all critical business functions and the effect that a specific disaster may have upon them

MIS Infrastructure

Includes the plans for how a firm will build, deploy, use, and share its data, processes, and MIS assets

Utility Computing

Offers a pay-per-use revenue model similar to a metered service such as gas or electricity.

Business Continuity Plan

Technology Recovery Strategies, Disaster Recovery Plan, Business Impact Analysis, Emergency Notification Services

Portability

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

Recovery

The ability to get a system up and running in the event of a system crash or failure

Multi-Tenancy

The cloud means that a single instance of a system serves multiple customers

Usability

The degree to which a system is easy to learn and efficient and satisfying to use
