Description

usability

- the degree to which a system is easy to learn and efficient and satisfying to use serviceability

- how quickly a third party 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

- computer chip performance per dollar doubles every 18 months sustainable or green MIS

- describes the production, management, use, and disposal of technology in a way that minimizes damage to the environment corporate social responsiblity

- companies' acknowledged responsibility to society Ewaste

- refers to discarded, obsolete, or broken electronic devices 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 business processes and systems carbon emissions

- the carbon dioxide and carbon monoxide produced by business processes and systems grid computing

- collection of computers, often geographically dispersed, that are coordinated to solve a common problem smart grid

- delivers electricity using two way digital technology virtualization creates multiple "virtual" machines on a single computing device data center

- facility used to house management information systems and associated components, such as telecommunications and storage systems 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 management effort or service provider interaction multi-tenancy in the cloud

- 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 possible the benefits of cloud computing cloud fabric controller

- individual who monitors and provisions cloud resources, similar to a server administrator at an individual company utility computing

- offers a pay-per-use revenue model similar to a metered service such as gas or electricity Infrastructure as a service (IaaS) - delivers hardware networking capabilities, including the use of servers, networking, and storage, over the cloud using a pay-per-use revenue model dynamic scaling - means the MIS infrastructure can be automatically scaled up or down based on needed requirements software as a service (SaaS) - delivers applications over the cloud using a pay-per-use revenue model Platform as a service (PaaS) - supports the deployment of entire systems including hardware, networking, and applications using a pay-per-use revenue model public cloud - promotes massive, global, and industrywide applications offered to the general public private cloud - serves only one customer or organization and can be located on the customer's premises or off the customer's premises community cloud - serves a specific community with common business models, security requirements, and compliance considerations hybrid cloud - includes two or more private, public, or community clouds, but each cloud remains separate and is only linked by technology that enables data and application portability cloud bursting - when a company uses its own computing infrastructure for normal usage and accesses the cloud when it needs to scale for peak load requirements, ensuring a sudden spike in usage does not result in poor performance or system crashes...
