Cloud-Computing allows individuals and organizations to purchase virtualized hardware (Infrastructure as a Service, IaaS), software platforms (Platform as a Service, PaaS) or applications/functionality (Software as a Service, SaaS) in a pay-as-you-go manner, comparable to the metered purchase of electricity, gas or water and is most often seen as a solution to improve scalability and reduce costs for IT solutions. Mobile Cloud-Computing (MCC) focuses on using mobile devices to engage cloud-hosted services and is therefore the intersection of cloud-computing and mobile-computing. The main driver for MCC is the decline of the PC and its replacement with the rising number of mobile devices (tablets & smartphones). According to Gartner in 2014 the combined shipments in the PC market (traditional PC, laptops & ultra-mobiles) are expected to reach 316 million units (worldwide). By contrast the worldwide sales of tablets are expected to reach 320 million units (worldwide) and smartphones (66% of mobile handset market) are expected to reach 900 million units. To overcome the apparent lack of computational resources when compared to PCs, Mark Baccue proposed the idea of using cloud-computing which has led to a virtuous cycle in which cloud-computing and mobile devices each are the driver for the growth of the other. It is therefore not surprising that MCC, as the combination of mobile and cloud-computing has establishing itself within IT as a key component/technology.***Current research and development within MCC is aimed at providing users via their mobile device rich experiences that are equivalent to those of traditional PC-based solution. However, as the number of mobile devices increase and their prices drop, more and more users begin to own multiple mobile devices e.g. smartphones and multiple tablets. This, in turn leads to the question of how to support users of multiple devices within MCC.***Since 2001 the long term goal of my research program has focused on the study and development of software infrastructure(s)/middleware to ensure that users of a mobile device are 1st class citizens within IT systems. My current focus on how to support the distributed execution of an app over multiple user owned mobile devices follows naturally in the course of my research program. As users begin to own multiple mobile devices, the question arises how they can be combined to provide more resources when executing an app. If the N devices have the same app instance installed, why not combine these instances to create a distributed app that can access the combined resources resulting in a more engaging MCC experience for the user. The goal of this research is to investigate, develop and evaluate middleware to support app instances on different mobile devices with respect to: Interaction, Coordination & Resource Sharing. ******

云计算允许个人和组织以按需付费的方式购买虚拟化硬件（基础设施即服务，IaaS），软件平台（平台即服务，PaaS）或应用程序/功能（软件即服务，SaaS），与计量购买电力，天然气或水相当，并且通常被视为提高可扩展性和降低IT解决方案成本的解决方案。移动的云计算（MCC）专注于使用移动的设备来参与云托管服务，因此是云计算和移动计算的交叉点。MCC的主要驱动力是PC的衰落及其被越来越多的移动的设备（平板电脑和智能手机）所取代。根据Gartner的数据，2014年PC市场（传统PC、笔记本电脑和超级手机）的总出货量预计将达到3.16亿台（全球）。相比之下，平板电脑的全球销量预计将达到3.2亿台（全球），智能手机（占移动的手机市场的66%）预计将达到9亿台。为了克服与PC相比明显缺乏计算资源的问题，Mark Baccue提出了使用云计算的想法，这导致了一个良性循环，其中云计算和移动的设备都是另一个增长的驱动力。因此，MCC作为移动的和云计算的结合体，在IT中成为关键组件/技术也就不足为奇了。* MCC目前的研究和开发旨在通过移动终端为用户提供与传统PC解决方案相当的丰富体验。然而，随着移动的设备的数量增加以及它们的价格下降，越来越多的用户开始拥有多个移动的设备，例如智能手机和多个平板电脑。这反过来又引出了如何在MCC内支持多个设备的用户的问题。自2001年以来，我的研究计划的长期目标一直集中在软件基础设施/中间件的研究和开发，以确保移动终端的用户是IT系统中的一等公民。我目前关注的是如何支持应用程序在多个用户拥有的移动的设备上的分布式执行，这在我的研究计划中是很自然的。随着用户开始拥有多个移动的设备，出现了一个问题，即在执行应用程序时如何将它们组合起来以提供更多资源。如果N个设备安装了相同的应用程序实例，为什么不将这些实例联合收割机以创建一个分布式应用程序，该应用程序可以访问组合的资源，从而为用户带来更具吸引力的MCC体验。本研究的目标是调查，开发和评估中间件，以支持应用程序实例在不同的移动的设备方面：交互，协调和资源共享。******
