Capacity Planning
Determines future environmental infrastructure requirements to ensure high quality system performance
Reliability
Ensures a system is functioning correctly and providing accurate information
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
MIS Infrastructure
Includes the plans for how a firm will build, deploy, use, and share its data, processes, and MIS assets
Failover

Cloud Computing
Refers to the use of resources and applications hosted remotely on the internet
High Availability
System is continuously operational at all times
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
Portability
The ability of an application to operate on different devices or software platforms
Recovery
The ability to get a system up an running in the even of a system crash of failure
Moore's Law
The computer chip performance per dollar doubles every 18 months
Usability
The degree to which a system is easy to learn and efficient and satisfying to use
Unavailable
Time frames when a system is not operating and cannot be used
Availability
Time frames when the system is operational
Backup
An exact copy of a systems information
Administrator Access
Unrestricted access to the entire system
Performance
Measures how quickly a system preforms a process or transaction
Grid Computing

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
Platform as a Service (PaaS)
A service that supports the deployment of entire systems including hardware, networking, and applications using a pay-per-use revenue model
Disaster Recovery Cost Curve
Charts the cost to the organization of the unavailability of information and technology and the cost to the organization of recovering from a disaster over time
Failback
Occurs when the primary machine recovers and resumes operations, taking over from the secondary server
Ewaste
Refers to discarded, obsolete or broken electronic devices
Accessibility
Refers to the varying levels that define what a user can access, view, or preform when operating a system
