在本文中，我们分析和研究在交互式移动的云应用程序的影响的云。为了研究这种影响，我们提出了云网络和服务架构的设计。我们的研究重点是文件编辑，视频流和协同聊天，这是代表性的企业应用场景。初步仿真结果表明，使用云的数据传输延迟和系统吞吐量方面的性能增益。当使用不超过两个cloudlet无线跳来传输数据时，基于cloudlet的方法在所有三个应用场景中都优于基于云的方法。在移动性下有更多的微云无线跳数，基于云的方法可以为一些数据传输提供更好的性能，即使基于微云的方法可以为大多数流提供更好的性能。在这种情况下，我们建议，应使用自适应方案。例如，可以使用在微云网络或云网络上做出智能决策的方案，无论哪个给出最小延迟。
In this paper we analyze and study the impact of cloudlets in interactive mobile cloud applications. To study the impact we propose the design of cloudlet network and service architectures. Our study focuses on file editing, video streaming and collaborative chatting which are representative enterprise application scenarios. Initial simulation results show the performance gains of using cloudlets over using clouds in terms of data transfer delay and system throughput. When not more than two cloudlet wireless hops are used to transfer data, the cloudlet-based approach outperforms the cloud-based approach for all three application scenarios. With more cloudlet wireless hops under mobility, the cloud-based approach can give a better performance for some of the data transfers even though the cloudlet-based can outperform the cloud-based approach for most of the flows. In such scenarios, we suggest that an adaptive scheme should be used. For example, a scheme making an intelligent decision on either the cloudlet network or the cloud network, whichever gives minimum delay, can be used.
