Fog Machine: A Fault-Tolerant System and Programming Framework for Cloud of Moving Things

在过去几年中，云计算和移动计算一直是计算趋势的两个主要驱动力。使用云计算为移动应用程序提供动力的挑战之一是服务器资源和客户端之间的巨大网络距离，以及随之而来的在提供有保证的服务质量方面的问题。为了解决这些问题，“边缘”计算范式，如雾，使云更接近客户端已经被提出。随着联网汽车和智能家居等物联网的蓬勃发展，边缘计算将在未来的任何计算基础设施中发挥更大的作用。这种云雾设备系统形成的三层分布式计算架构带来了许多新的挑战。其中最主要的是系统的可编程性。

Cloud computing and mobile computing have been two dominant drivers of computing trends in the last few years. One of the challenges of using cloud computing to power mobile applications is the significant network distance between the server resources and the clients and the consequent problems in delivering guaranteed qualities of services. To address these problems “edge” computing paradigms such as fogs that bring clouds closer to the clients have been proposed. With the impending boom of Internet of Things such as connected cars and smart homes, edge computing is poised to play a larger role in any computing infrastructure of the future. The three-layered distributed computing architecture formed by such a cloud-fog-device system introduces many new challenges. Chief among them is the programmability of the system.
