Cloud computing is utilizing the recent large expansion of Internet and network technologies where the increase in the data size and transfer speed made it possible to make the Internet or the cloud a possible host for all or most users’ applications and data. With this new technology, several changes are expected to occur in the information technology fields and systems to adapt to this field or technology. In this chapter, the author focuses on the possible impact on the way software companies will develop their software products. For example, the traditional client server system architecture is expected to be significantly impacted with cloud computing new framework.
