What is fog computing?

What is fog computing?

After been using the cloud computing concept in our daily language for several years, it is time to add a new extension to it: the fog computing. However, what does the concept really mean? What benefits can it offer to the end user? Let’s clear up this vague fog about the meaning of fog computing.

Fog computing concept has been recently coined by CISCO. In spite of being a new term, it is a concept that Wattio uses as its technological strategy since the very beginning.

What is it?

The fog computing is a way of processing data. Part of the data that different devices connected to the network emit, is saved within the devices, instead of sending them all to the cloud. That is why it is called “fog”: now, the cloud is not the place where all the data is gathered, it is a “fog” formed by the processed data saved in the cloud and in the intelligent devices.

What benefits does it offer?

Why is it interesting to storage data in the same technological devices instead of in the cloud? This question may surely be in the minds of several readers. It seemed like the cloud computing had solved all our problems of the data accessibility, so, why does the fog computing exist?

  • Less consume of data and the reduction of the Internet congestion.
  • Consequently, less costs and latency.
  • Less bandwidth consumption.
  • Improvement of the security of the encrypted data: the information is closer to the final user, so there is a reduction of the exposition and vulnerability.
  • Improvement of the scalability potential, key in a sector with such a growth potential.
  • Reduction of the reaction time of the system.
  • The system continues working when there is no Internet connection (key factor when selecting a connected home system).
  • Considerable reduction of the risk of suffering breakdowns or blocks, because the intelligence is spread in different core of action. Growth of the balance and equilibrium.


Fog computing and the Smart home

Fog Computing is closely related to the Internet of Things (IoT). These intelligent devices are able to retain data, so they do not need to connect to the internet to respond to the user. Consequently, the answer is quicker, and because of they do not need to connect to the Internet, the security of the user increases.  

One of the moments in which the benefits of the fog computing are more evident is when the system is not able to connect to the network. Imagine what would have happened if Wattio’s automation system hadn’t had this processing… when the user lost Internet connection or there was any problem with the system, the user would not be able to switch on the heating or the camera would stop recording.    

Wattio’s intelligent devices have this system that makes it possible. Among many other things, the correct local functioning of them, even when there is a system error or there is no internet connection. As a result, when there is a problem, the different gadgets of the smart home know how to work because a part of the data about its performance is stored at the devices: they continue working, following the calendars that each user has previously set, and the interaction between the different devices continues working.  

The multiple options that the fog computing enables has become it in a more utilized concept by the citizens; however, the majority does not even know its meaning. Now, we will be able to talk about it with certainty when people refer to the mysterious fog.
