Introduction to Cloud Computing

In the context of todays p atomic number 18ntage environment, theres a trend that sees reckon resources becoming cheaper, more correctly and more ubiquitously available give thanks to fast-growing development of touch on and storage technologies, along with the viral success of the Internet (Panzieri et al., 2012). This technological progress led to the actualization of a new range of a function called Cloud Computing, which resources are provided as general utilities that can be requested and released on-demand by users finished the Internet (Zhang et al., 2010).\nCloud compute gained an increasing popularity in the figuring world in the finish five years, as education Technology saw in outsourcing and resources decentralization the real telephone circuit success. In fact, the combination of weather vane 2.0 plus Cloud figure allowed the shift from virtual to virtualized organizations, with teams hardened in different locations close to the world, connected by expe ditious technology, netbooks, Web 2.0 tools, and Cloud service (Hwang et al., 2012).\nHowever, although Cloud introduced a comparatively new way of perceiving IT, as it can now be presented as a pay-per-use service, just about of the features were already present in some of the technologies already in use, such as geographically distributed resources, and location and access transparency. In fact, those concepts are already at the base of distributed computing, and Clouds can be considered extensions of Distributed systems, with the additional ability of pathetic storage and computational entropy from physical machines to remote, possibly unknown, locations, which are accessible in a simple and pervasive way.\nOften, the greenback from Distributed computing is perceived as blurred (Adolph, 2009; Foster, 2008), but, theoretically, it is possible to appoint the main difference surrounded by these two concepts: Distributed computing is a field of computer information that\ndeals with those systems that utilizes the power of multiple self-gover...
