摘要:

全世界安装了数以亿计的网络摄像机。每个都能提供大量的实时数据。分析这些摄像机生成的大量数据需要大量的计算资源,并且需求可能会随着时间的推移而变化。云计算最有希望按需提供所需的资源。在这篇文章中,我们研究了在分析来自网络摄像机的实时数据流时如何分配云资源。资源管理器会考虑许多影响其决策的因素,包括分析类型、数据流的数量和摄像机的位置。然后,管理器选择最具成本效益的云实例类型(例如CPU与GPGPU),以满足分析流的计算需求。我们使用Amazon Web Services评估我们方法的有效性。实验表明,实际工作负载的成本降低了50%以上。

英文摘要:

Hundreds of millions of network cameras have been installed throughout the world. Each is capable of providing a vast amount of real-time data. Analyzing the massive data generated by these cameras requires significant computational resources and the demands may vary over time. Cloud computing shows the most promise to provide the needed resources on demand. In this article, we investigate how to allocate cloud resources when analyzing real-time data streams from network cameras. A resource manager considers many factors that affect its decisions, including the types of analysis, the number of data streams, and the locations of the cameras. The manager then selects the most cost-efficient types of cloud instances (e.g. CPU vs. GPGPU) to meet the computational demands for analyzing streams. We evaluate the effectiveness of our approach using Amazon Web Services. Experiments demonstrate more than 50% cost reduction for real workloads.
