Fog computing: A brief note

You might have hearing the term fog computing.But confused on what it really is.It is actually a computing concept forwarded by Cisco.It can be considered as an advancement or development to cloud computing environment.

‘Internet of things’ is providing each and every object an IP address.This idea will lead to great confusions.According to analysts by the end of 2020 about 50-75 billion devices will be connected.This will make the data warehouses full.And it is said that the future computing is on cloud.This demands processing and storing of huge data in cloud storages which requires high bandwidth.Otherwise it affects the quality and time of processing.To prevent this,Cisco introduced a concept called fog.

Basically Fog is a computing model designed for internet of things.The difference between the two models is same as the difference between the real cloud and fog.Cloud is far away from the people.But fog is near to people.While Cloud stores data somewhere in it’s server where in which data have to travel long distance,fog stores the data near the user.ie in routers,set top boxes or access points.Thi s reduces the requirement of high bandwidth.

Here data is processed locally.This make it possible for small computing tasks to be done without fetching data from the server.Instead of batch processing,fog make use of real time interactions.

Iox architecture

It is an application enablement framework presented by Cisco to give life to fog computing model.This is a joint infrastructure combining elements of open source software linux and Cisco’s operating system ios(internetworking operating system).

Applications:

According to cisco the following are the main applications of fog computing.

a.Connected cars

by 2017,most of the cars on the streets will be connected.Cisco tells that the real time interaction of fog help car’s access points and traffic lights get connected

b.Smart grids

Intelligent electrical grids can make use of fog model.Here the energy sources are being shifted considering the availability and requirement of energy load balancing in smart energy distribution’s network edge demands such a model.

c.Smart traffic lights

This enables an ambulance to pass through traffic smoothly by sensing the flashing lights of ambulance.

d.Self maintaining trains

Here the senser to monitor the ball bearings of train will give you the environmental conditions and can give alert to control room if it find anything wrong.

There are many more applications to fog computing.We can say that upto a limit fog can change the future of computi ng.especially internet of things.
