Definition of Cloud Definition

Cloud Introduction | Ericsson Internal | 2015-12-13 | Page 9

Cloud computing is 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 this cloud model is composed of five essential characteristics, three service models, and four deployment models.
