Abstract

This chapter explores emerging technologies centered around cloud computing. From the technological point of view, cloud computing was born as a result of the emergence and the convergence of contemporary technologies. This chapter regards technological aspects of cloud. In the software area, Virtualization Technology and Web Services; in the hardware area, shared compute components (i.e., multicore processors); in networking, security, network virtualization, Virtual Private Network (VPN), virtual firewalls, and network overlay are the promising technologies for the future complex computing infrastructures. In this chapter, the authors review these technologies and describe how they contribute to the anatomy and the characteristics of cloud computing. These technologies constitute the building blocks of cloud computing technologies and infrastructures.

1. Introduction

From the technological perspective, cloud computing was born as a result of the emergence and the convergence of contemporary technologies. These technologies came from advances in software, hardware and networking.

Virtualization technology and Web services from the software domain, shared compute components such as symmetric multiprocessing (SMP), multicore processors and Non-Uniform Memory Access (NUMA) from the hardware domain, network virtualization, and network overlay from the networking domain, virtual firewalls, and virtual private network (VPN) from network security are a few technologies that constitute the building blocks of cloud computing technologies and infrastructures.

In this chapter, we will review these technologies and describe how they contribute to the anatomy and the characteristics of cloud computing.
