Definition
A model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.
Alternative Definitions
- Definition 2
A model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provided to users with minimal management effort or service provider interaction. U. S. government’s interagency committee authorized to review certain transactions involv- ing foreign investment in the United States and certain real estate transactions, in order to determine the effect of such transactions on the national security of the United States.
- Definition 3
The practice of using a network of remote servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer. Also called on-line computing. Election technologies are evolving in parallel with other commercial information systems. Election officials may be managing voter and election data, stored on computers, outside of their organization. Cloud computing requires an appropriate security strategy to ensure the protection, availability and integrity of data and programs store in the cloud.
- Definition 4
A model for enabling on-demand network access to a shared pool of configurable computing capabilities or resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.
- Definition 5
A model for enabling on-demand network access to a shared pool of configurable IT capabilities/ resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. It allows users to access technology-based services from the network cloud without knowledge of, expertise with, or control over the technology infrastructure that supports them. This cloud model is composed of five essential characteristics (on-demand selfservice, ubiquitous network access, location independent resource pooling, rapid elasticity, and measured service); three service delivery models (Cloud Software as a Service [SaaS], Cloud Platform as a Service [PaaS], and Cloud Infrastructure as a Service [IaaS]); and four models for enterprise access (Private cloud, Community cloud, Public cloud, and Hybrid cloud).
