Fog Computing Now?

Fog Computing Has Solid Use Cases but with Real Challenges

In a nutshell Fog Computing is a compute layer between the Cloud and the Edge. Where Edge Computing could send huge streams of data directly to the Cloud, Fog Computing can receive the data from the edge layer before it reaches the Cloud and decide what is relevant.

IoT applications are good uses of Fog Computing. Imagine sensors connected to an edge server that takes measurements every single second. Instead of sending huge amounts of data to the Cloud, a fog layer over a localized network can receive this data and decide what subset (e.g., exceptions) is worth sending on.

The impact on bandwidth and latency could be massive depending on the application.

Here is our monthly curated list of thought-provoking articles, blog posts, and videos on Fog and Edge Computing:

What Is Fog Computing: Components, Examples, and Best Practices

By Ramya Mohanakrishnan

This article explains in a straight-forward manner how fog computing introduces a layer between Edge devices and the Cloud.

This layer relies on many small computing servers that reside near the edge devices and not necessarily on the device itself. The servers are connected to each other and to centralized cloud servers, enabling the intelligent flow of information.

Fog Computing: Concepts, Frameworks and Applications

By Dr. Ravi Tomar

This book is a good reference for distributed computing professionals looking to improve their understanding of security and connectivity for Internet of Things (IoT) or other applications that require low latency.

Understanding Fog Computing vs. Edge Computing

By Andrew Overheid

Fog Computing and Edge Computing are both enablers of data traffic to the Cloud. Unfortunately, the Cloud has its limits in terms of capacity, security and efficiency when connected directly to edge devices.

Learn how Fog Computing solves this problem in this article/video.

Video: What Is Edge Computing?

By IDG TECHtalk

Edge computing is computing that takes place at the edge of of the Cloud or corporate networks, with “the edge” being defined as the place where end devices access the rest of the cloud/network.

These devices could be phones, laptops, industrial robots, and sensors. Learn more about how this process works with this short 3-minute video.
