Cloud computing has opened new horizons in the group work, with the possibility of increasing the quality of the products and/or services, in very short timeframes and with lower costs. Besides, there is a reduction of the costs for the maintenance of servers and/or the updating of the versions of the operative services, special applications, etc., with which the local and international users work daily inside a private, public or mixed institution. The safety and privacy of the data which are in the cloud constitutes a key element in the reliability of the interchange of original ideas for the development of avant-garde projects.The new virtual communities which will be born from these clouds will see the integration and confederation of the diverse models of networks that have existed: intranet, extranet, internet, etc., with the novel micro computing and multimedia mobile phone devices. Here are some of the main goals, which we intend to discuss in this Third International Conference on "Horizons for Information Architecture, Security and Cloud Intelligent Technology (HIASCIT 2015): Programming, Software Quality, Online Communities, Cyber Behaviour and Business".In other words, the current international conference is aimed at all the professionals, experts, students, professors, researchers, businessmen, etc. hailing from the formal sciences and the factual sciences. This is another of the reasons why, when we refer currently to the architecture of information, it is claimed that it is “an art and a science” to find the best possible solutions to the problems posed, from the programming of efficient and intelligent applications down to the management of the online communities. In this sense, cloud computing can increase the business in each one of the environments of the human being, going from ecological tourism, three-dimensional design, etc.
