Fog & Cloud Computing

What is Fog Computing  ?

  • Fog computing or fog networking, also known as fogging.
  • Architecture that uses one or more collaborative end-user clients or near-user edge devices.
  • Carry out a substantial amount of storage (rather than stored primarily in cloud data centers), communication (rather than routed over the internet backbone), control, configuration, measurement and management (rather than controlled primarily by network gateways such as those in the Cellular network.
  • Eliminae bandwidth bottlenecks and latency Issues

What is Edge Computing?

  • Edge computingis a method of optimizingcloud computing systems by performing data processing at the edge of the network near the source of the data.
  • Reduces the communications bandwidth needed between sensors and the central datacenter by performing analytics and knowledge generation at or near the source of the data.
  • This approach requires leveraging resources that may not be continuously connected to a network such as laptops, smartphones, tablets and sensors.
  • Edge Computing covers a wide range of technologies including wireless sensor networks, mobile data acquisition, mobile signature analysis, cooperative distributed peer-to-peer and more.

Fog VS. Edge Computing Differences

  • The key difference between the two architectures is exactly where that intelligence and computing power is placed.
  • Fog computing pushes intelligence down to the local area network level of network architecture, processing data in a fog node or IoT gateway.
  • Edge computing pushes the intelligence, processing power and communication capabilities of an edge gateway or appliance directly into devices like programmable automation controllers (PACs).
