What is "Fog Computing" necessary for IoT?

This is Ohara from the Technical Sales Department

As the title suggests, this time I will write about "Fog Computing"

is not a very familiar term,
fog computing

The origin of the term fog computing

In the IT world, the word "cloud" literally translates to "cloud," but
the word "fog" literally translates to "mist.
" "Fog" is used to indicate a location closer to the user than the "cloud."

Another term similar to fog computing
is "edge computing."

This literally represents the "edge," and,
similar to fog computing, it involves data processing and distribution closer to the user.

Requirements for building IoT

Recently, companies have been making various efforts to introduce IoT systems

Furthermore, as shown in the diagram below,
traditional cloud configurations
have challenges in achieving satisfactory results due to issues with real-time response and transactions.

This is where the concept of "fog computing" comes in.
A configuration that adds fog computing to a conventional cloud configuration
looks like the diagram below.

summary

The concept of fog computing exists in both cloud environments and endpoints.
Furthermore, to implement IoT, building a cloud environment is essential, not just a fog environment.
