Abstract
Cloud Computing has changed the paradigm of traditional computing, freeing end users and companies from having their own computing resources. Instead, users have access to seemingly unlimited resources, with great availability and reliability, in a transparent and ubiquitous way, using thin clients through the internet. In this article, the NIST Cloud Computing definition is presented, describing its characteristics, services and implementation models. Some considerations are made regarding traditional computing and the advantages of Cloud Computing, which was made possible with the development of technologies such as Grid Computing and Virtualization. Economies of scale, transparent engineering and user focus are the key features of Cloud Computing success.
Keywords
Cloud Computing, Grid Computing, Virtualization.

Abstract
The emergence of the smartphone as a highly complex technology was accompanied by mobile operating systems (OS), large developer communities, content providers and complex networks, forming together digital infrastructures. These smartphones have become powerful devices being basically miniature versions of personal computers. Multiple factors have had a significant effect on the evolution of these platforms including graphical user interfaces, development platforms, business models and value extraction principles. However, the growing popularity and sophistication of smartphones has also heightened concern about the privacy of users using these devices.
