Cloud Computing: Fundamentals, Critiques and Challenges

Abstract

Cluod Computing is a broad term that describes a wide range of technological services. To truly understand how the cloud can be valuable to an organization, it’s important to understand what the cloud really is and what its different components are. Since the cloud is a broad set of services, organizations can choose where, when, and how to use cloud computing. This paper explains the different types of cloud computing services called SaaS (Software as a Service), PaaS (Platform as a
Service) and IaaS (Infrastructure as a Service) encompassed under the concept of “Cloud Services
Stack” and presents examples of case studies. The deployment and implementation models of different types of cloud are described, some implementations for disruptive technologies (Machine Learning, IOT, ubiquitous robotics, Blockchain). There are also drawbacks, critical positions and challenges related to this concept
