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
