After the success of the first edition of this workshop, held on 11-12 November 2012 in Agadir, we have the great pleasure to launch its second version in Agadir. Cloud computing comes into focus for IT needs as a way to increase capacity or add capabilities, on the fly, without investing in new infrastructure, training new personnel, or licensing new software. Cloud computing encompasses any subscription-based or pay-per-use service that, in real time over the Internet, extends IT's existing capabilities. Therefore, Cloud computing has gained great attention from both academia and Industry. On the other hand, Mobile Computing is dedicated to addressing the challenges in the areas of mobile computing networks, systems, algorithms and applications that support the symbiosis of mobile computers. On the other hand, the theme of cloud security turns out to be a subject of the actuality and continues to attract interest from various actors involved in this type of network. The Mobile Cloud Computing Technologies and Security session will address topics related to cloud and Mobile computing, including computing and data centers, the cloud network and its security, and its end-user services. The challenges facing architecture, performance, reliability, security, maintainability and the virtualization of the cloud will be included.
