Both cloud computing and fog computing are a part of computing technologies.
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.
