Fog and Cloud Computing
• Fog computing or fog networking, also known
as fogging, is an architecture that uses edge devices to
carry out a substantial amount of computation, storage,
and communication locally and routed over the internet
backbone.
• Cloud computing is the on-demand availability
of computer system resources, especially data storage
(cloud storage) and computing power, without direct
active management by the user. The term is generally
used to describe data centers available to many users
over the Internet. Large clouds, predominant today,
often have functions distributed over multiple locations
from central servers. If the connection to the user is
relatively close, it may be designated an edge server.

Fog Computing
• Fog computing, also called fog networking or
fogging
• It describes a decentralized computing structure
located between the cloud and devices that
produce data.
• This flexible structure enables users to place
resources, including applications and the data
they produce, in logical locations to enhance
performance.
How does fog computing work?
• The fogging (Fog Computing) is to improve
efficiency and reduce the amount of data
transported to the cloud for processing,
analysis and storage.
• This is often done to improve efficiency,
though it may also be used for security and
compliance reasons.
How fog computing can be used with
IoT?
• Fog nodes at the network edge nearby acquire
the data generated by IoT devices such as
sensors and devices, process and store data by
network edge devices in local area network.
• It considerably reduces data movement across
the Internet and provides speedy high-quality
localized services sustained by endpoints .
