Cloud computing Abstract During the last decade, the Information and Communication Technol -ogy (ICT) industry has been transformed by innovations that fundamentally

the cloud computing, which will be investigated in details in this Chapter 2. 1 Introduction The development of cloud computing started years ago with the emergence of grid

computing. Grid computing can be explained as the allocation of several computer systems in a parallel structure to solve one problem 1. Cloud computing is

similar to Grid but differs in the sense it aims to provide on demand access to a

Service Models Dhar 4 defines cloud computing as the structure that provides the ability to the

users to utilize the hardware, software, and networking infrastructure over the Internet. From this definition, three levels of cloud computing can be defined (see

Fig. 2. 1). The first level is the Software as Service (Saas). In this layer, the

In addition to these, a new abstraction level in cloud computing has emerged recently and called Network as a Service (Naas.

The first example is Amazon EC2 which allows users to rent virtual computers on which to run their own computer applications.

value of cloud computing and are increasingly transitioning to the cloud. However despite all these trends, there are many challenges that face the research and
