What is Edge Computing and Why does it matter in IoT?

Definition, Vision, Opportunities, Challenges and Case Study
THE ROLE OF EDGE COMPUTING IN IOT
- Sameer Ahmed

Edge computing is a “mesh network of micro data centers
that process or store critical data locally and push all
received data to a central data center or cloud storage
repository, in a footprint of less than 100 square feet,”
according to research firm IDC.
Edge computing is a distributed, open IT architecture that
features decentralized processing power, enabling mobile
computing and Internet of Things (IoT) technologies. In
edge computing, data is processed by the device itself or by
a local computer or server, rather than being transmitted to
a data centre
DEFINATION - WHAT IS EDGE COMPUTING?

Edge Computing helps enterprises address cost,
bandwidth and latency issues across a broad range of IoT
applications. Here are three key reasons why you need
Edge Computing:
 Reduce the Amount of Data Transmitted and Stored in
the Cloud
 Reduce the Lag Time in Data Transmission/Processing
 Reduce the Signal to Noise Ratio
WHY DO WE NEED EDGE COMPUTING?

CHALLENGES AND OPPORTUNITIES
Challenges
General purpose computing on edge
nodes
Discovering edge nodes
Partitioning and offloading tasks
Uncompromising Quality-of-service
and experience
Using edge nodes publicly and
securely
Opportunities
Standards, benchmarking and
marketplace
Frameworks and languages
Lightweight libraries and algorithms
Micro operating systems and
virtualization
Industry-academic collaborations

EDGE COMPUTING ARCHITECTURE
Let’s see the big picture below to understand the main components of this architecture.
The diagram above shows the edge side and cloud side. In the edge side the things could be sensors, actuators,
devices and a crucial thing called gateway. This gateway has the responsibility to establish communications between
things and cloud services and also orchestrate the actions between the things.

EDGE COMPUTING BENEFITS - KEY DRIVERS FOR SMART MANUFACTURING
There are many advantages to organizations when they adopt the edge
platform, so let’s see how edge computing is proving to be beneficial for
enterprises:
 Quick responses – Due to high computational power at the edge of a
device, the time taken to process data and send back to the host is
very quick. There is no trip to the cloud for analysis which makes the
process faster and highly responsive.
 Low operating cost – There are almost no costs involved due to
smaller operations and very low data management expenses.
 Security of the highest level This technology also allows filtering of
sensitive information and transfers only the important data, which
provides an adequate amount of security.
 A pocket-friendly solution –Edge computing performs data
analytics at the device location which saves the final costs of an
overall IT solution.
 A true connection between legacy and modern

FMCG – CPG Line Monitoring:
As packaging lines carry variety of old and new machines, many aren’t designed to share data. The solution demanded retrofitting of
hardware and custom dashboards to visualize multiple lines and machines. Altizon, along with the hardware partner, designed an
integrated IoT solution. It deployed high quality wireless object detection sensors on case sealers, wrapping machines, and box printers to
capture real-time operating pulse. The 24/7 real-time machine data at Datonis Edge helped analyze equipment failure & generate alerts.
The business intelligence reports with machine idle time, breakdown reason codes, and overall productivity/OEE data helped management
in better planning and addressing issues..

Deployment of Enterprise & Campus Networks:
A reliable network that’s readily available is crucial for
large enterprises or campus networks. Numerous
individuals using the same network can result in high
latency for the end users. MEC resolves that issue of high
latency. MEC in an enterprise network will allow copious
employees simultaneous access to a company’s intranet,
in order to complete mass training without halting
network speed.
USE CASES OF EDGE COMPUTING

Edge computing has been implemented in a variety of IIoT deployments; however, the need to modernize
edge architectures became apparent with the emergence of cloud computing. The rapid decline in processor
and memory cost enables more advanced decision-logic closer to where the data is created, at the edge. The
industry has learned that a “one-size-fits-all” approach has never been adequate for IIoT.
The next phase of the work will be to address these concerns in the Technical Report. While we have tried to
lay out the significance of edge computing of future IIoT systems, we know it is a never-ending task as new IIoT
applications and new considerations appear every day. We intend this paper to trigger more in-depth
conversations and invite your participation.
This is not the end; rather, a beginning.
