FOG COMPUTING研究中的初级概念

”Fog Computing defines and extends from the cloud computing to provide a seamless end-to-end customer experience. Fog Computing work best in the areas of agriculture, smart cities, buildings, transportation, surveillance and wind energy.”

雾计算的定义主要是云的拓展,为使用者提供一个与云无缝衔接的体验。雾计算只要在农业、智慧城市、智慧建筑、智能交通、监控和风力发电等领域。

  • Edge and Fog are also the same thing
  • Fog is a replacement also for cloud
  • A Fog is new name also for existing architectures
  • Fog nodes are also in constrained devices
  • The Fog computing applicable to wireless environments
  • Fog creates new silos and also eliminate some physical silos
    • 注释
      • 边缘计算和雾计算指代的基本是同一件事
      • 雾计算也包含云计算
      • 雾计算涵盖很多已经存在的架构
      • 雾计算在无线通信中也适用
      • 雾计算在使用新设备的同时取代了很多旧的物理设备

云计算的主要限制(边缘计算之惯例,不一定准确!)

  • -Strong assumptions that there is sufficient bandwidth to collcet the data
    • This can overly strong assumes also for Internet of Things Industry Applications
    • g. Energy Utility 0.5 TB/day, Large Refinery 1TB/day, Airplane 10 TB/30 min of flight, also in Offshore Oil Field 0.75 TB/Week.
      •   云计算假设有足够的带宽来传输数据
        •   但是在物联网工业应用中数据量和数据量的增速很快
          •   举例来说,发电厂 0.5TB/天;大型炼油厂 1TB/天,飞机 10TB/半小时航程,海上油井 0.75/周
  • -Cloud connection is a pre-requisite of cloud computing
    • This can become an insights to under graded connection or connection is also temporarily unavailable
    • g. Driver Assistance Applications
      •   云计算必须与云相连接
        •   但是在一些场景下未建立连接或者链接会是不是中断
          •   比如无人驾驶
  • -Cloud computing analytics centralises-Defining the lower bound reaction time of the system
    • Some IoT systems need to also be able to wait for the data to get to the cloud
      •   云计算的数据分析依赖云数据中心,这样带来了响应时间与带宽的权衡问题
        •   比如一些物联网系统必须要等待数据传输到云端进行处理。
  • -Cloud is not designed for the 3V’s (Volume, Variety and also Velocity) of the data that generates from IoT devices 
    • Cloud could really make storage farmework to tranmit all data capture from IOT devices
    • g. Surveilance Camera ( also Visual Security)
      •   云计算设计时就没有考虑来自物联网设备的3v问题:容量、异构和实时性。
        •   云端很难胜任所有来自物联网设备采集数据的存储
          •   比如监控摄像机和视频安保心疼
