Both cloud computing and fog computing are a part of computing technologies. Where lies the difference?

There is a lot about cloud computing as the most prominent form of IoT data management. Along with cloud computing, fog computing is becoming popular as well. Fog and cloud both computing technologies serve the company to govern their communication effectively and efficiently.

Fog computing is an addition to cloud computing that imitates an instant connection on data centers with its multiple edge nodes over the physical devices. It establishes a missing connection between cloud computing as to what data needs to be sent to the cloud and the internet of things. 

Cloud Computing vs Fog computing 

Latency

Cloud computing has high latency compared to fog computing.

Fog computing has low latency.

Magnitude

Cloud Computing does not provide any reduction in data while sending or transforming data. Fog Computing reduces the amount of data sent to cloud computing.

Responsiveness

The response time of the cloud computing system is low.

The response time of the fog computing system is high.

Security

Cloud computing has less security compared to Fog Computing

Fog computing has high Security.

Speed

Access speed is high depending on the VM connectivity.

High even more compared to Cloud Computing.
