IntroductionCloud Computing (CC) has been in recent years an excellent platform for the development of computational solutions for multiple fields of knowledge. This new computational approach has introduced a large number of advantages but also entails a number of challenges. The CC was a response to the current scenario where tasks such as sharing, obtaining and handling massive amounts of information are a reality. However, this scenario proves to be extremely demanding in terms of computing resources that have to exist for it is demonstrated feasible to perform these tasks with acceptable performance.The CC has, with regard to computing resources, a vision of unlimited resources. Not because they in fact are, but by a transparently scaling approach. That is, the ability to grow cloud resources (by adding resources to a distributed cluster) shows become invisible to the end user. This just sets and engages resources, scaling this hiring according to their temporal needs without resource scarcity concerns. In fact, this is not the concern of the CC customer, but of the provider of the resources. This way of looking at computing presents to customers (typically organizations) an important advantage. It ceases to be a concern installation, maintenance and processing infrastructure management.
AbstractThis paper presents a review of the main characteristics of cloud computing, where they are exposed, their main components and ways of use. In addition to the technological review that is done, is also carried out. To understand how cloud computing can lead to a powerful ally of SMEs in the context of organizational competitiveness in a world where the role of information systems for a long time proved decisive, it is a reflection that the SMEs, whose core business is not technology, need to be carried out.
