Foundations of Cloud Computing

Abstract

This is a foundational chapter, looking at the historical evolution of various networking and computing technologies that led to Cloud Computing. This is a must-read chapter for people not familiar with the past trends and progress that led us from large mainframe computers to PCs and now back to large data centers hosting Cloud Computing servers. In parallel, there was a significant progress made in Enterprise IT, Web Services, and service-oriented architecture (SoA). We will review and compare top-down versus bottom-up SoA solution approaches, implementation of Private and hybrid Clouds. At the end, we will look at the Internet security threat models and an open Web application security project.
