Definition of Cloud Computing Cloud computing is a model for enabling 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. This cloud model promotes availability and is composed of: Source: NIST Definition of Cloud Computing v15NIST Definition of Cloud Computing v15 3 Service Models 4 Deployment Models 5 Essential Characteristics
