MAIN MODELS FOR PROVIDING CLOUD COMPUTING SERVICES

Abstract

This paper provides a systematic analysis of the deployment and implementation models of cloud computing infrastructure. Specifically, it explores the distinctive features, advantages, and limitations of private, public, and hybrid cloud systems through a comparative lens. Drawing upon the criteria established by the Gartner analytical company and NIST (National Institute of Standards and Technology), the study delineates the conceptual differences between cloud computing and mere virtualization. Furthermore, it thoroughly examines the five fundamental characteristics of cloud computing: on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service. The research insights serve as a methodological framework for enterprises and organizations to select the most appropriate cloud architecture.
