CLOUD COMPUTING (NIST)CLOUD COMPUTING (NIST)

• Cloud computing is a pay-per-use model Cloud computing is a pay-per-use model for enabling available, convenient, on-for enabling available, convenient, on-demand network access to a shared pool demand network access to a shared pool of configurable computing resources (e.g., of configurable computing resources (e.g., networks, servers, storage, applications, networks, servers, storage, applications, services) that can be rapidly provisioned services) that can be rapidly provisioned and released with minimal management and released with minimal management effort or service provider interaction. This effort or service provider interaction. This cloud model promotes availability and is cloud model promotes availability and is comprised of five comprised of five key characteristics,key characteristics, three three delivery modelsdelivery models, and four , and four deployment modelsdeployment models. .

The customer generally to consumer demand. The customer generally has no control or knowledge over the exact has no control or knowledge over the exact location of the provided resources. Examples of location of the provided resources. Examples of resources include storage, processing, memory, resources include storage, processing, memory, network bandwidth, and virtual machines. network bandwidth, and virtual machines.
