这是一个大数据的时代,尤其是物联网将成万上亿计的网络传感器嵌入到现实世界的各种设备中,如移动电话、智能电表、汽车和工业机器等,用来感知、创造并交换数据,无处不在的传感网络带来了大量的数据,这些数据正日益成为与实物资本和人力资源同等重要的生产要素。与此同时,云计算为物联网所产生的海量数据提供了很好的存储空间,并使得实时在线处理成为可能。特别是云计算概 This is an era of big data. In particular, the Internet of Things embeds billions of network sensors in real-world devices such as mobile phones, smart meters, automobiles and industrial machines to sense, create and exchange Data, ubiquitous sensor networks, bring a wealth of data that is increasingly becoming an equally important factor of production as physical and human resources. At the same time, cloud computing provides great storage for massive data generated by the Internet of Things and makes real-time online processing possible. In particular, cloud computing
