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".

Since this is a term that you may not be familiar with,
I would like to start with an overview of fog computing.

Origin of fog computing

The literal translation of the word "cloud" in the IT world is "cloud," but
the literal translation of the word "fog" is "fog."
It is expressed as "fog" because it is located closer to users than "cloud".

also a term similar to fog computing,
``edge computing.''

This literally refers to the "end side" and,
like fog computing, it processes and distributes data close to the user side.

Required conditions when building IoT

Recently, companies are making various efforts to introduce IoT mechanisms.

Additionally, as shown in the diagram below,
traditional cloud configurations have issues with real-time response and transactions,
making it difficult to obtain sufficient results.

This is where the concept of "fog computing" comes into play.
A configuration in which fog computing is added to a traditional cloud configuration
is shown in the diagram below.

summary

The concept of fog computing resides in cloud environments and endpoints.
Furthermore, in order to establish IoT, it is essential to build not only a fog environment but also a cloud environment.
