Computação em nuvem: uma análise comparativa das plataformas disponibilizadas por Amazon, Google e Microsoft

Abstract

The current scenario indicates a gigantic connection capacity, producing an enormous amount of data constantly, based by the market which calls for increasing efficiency in the treatment of information and in the production of offers and services. Cloud computing gains notoriety precisely because it optimizes the provision of services aimed at this market, generating much cleaner, more efficient and cheaper IT. Cloud computing abstracts from many of the most complex concepts in computing and delivers a simplified and on-demand product, as a service, where users pay exactly and only for what they use. Giant companies in the IT market like Amazon, Google and Microsoft then they take the market and compete in a very interesting way users and companies instigated by the possibilities of cloud computing. Therefore, this research sought to compare the various general aspects and specificities available to each of these three companies with regard to the provision of cloud services (infrastructure, platform and/or software) to assist in a conscious choice. We show from the architectural basis of each infrastructure or platform, through the main services and culminating a comparative study of several points in which there is common between the three offers. We take into account relevant issues such as price, market presence, infrastructure, data processing, security, among many others. Finally, we present our overview and the direction for decision-making.
