Why Edge Computing Matters for Modern Enterprises
Most enterprises try to harvest the data they are producing or coming in contact with. Conventionally, data processing and analysis are performed on local or cloud servers. The data collected is sent to the enterprise’s Edge Computing Platform or transmitted to the cloud via broadband, where applications analyze it and generate insights.
However, the transmission of data to and from the site where it is generated leads to high latency, increases the chances of data getting corrupted or breached, and creates dependency on continuous internet connectivity. In many cases, setting up a broadband connection for data transmission is infeasible, such as in remote locations with no internet connectivity or in projects where data is generated at multiple sites with high frequency.
Edge computing platforms are transforming how data from IoT sensors worldwide is processed, stored, and distributed. This approach eliminates the inefficiencies of centralized computing by shifting data processing closer to its source. Azure IoT Edge plays a critical role in enabling real-time processing at the edge, reducing reliance on cloud servers and improving response times for critical applications.
What is Edge Computing?
Edge computing is a distributed computing paradigm in which processing and computation are performed mainly on classified device nodes known as smart devices or edge devices as opposed to processed in a centralized cloud environment or data centers. It helps to provide server resources, data analysis, and artificial intelligence to data collection sources and cyber-physical sources like smart sensors and actuators.
It is a way to streamline the movement of traffic from IoT devices and implement real-time local data analysis. Data produced by Internet of Things devices is processed where it is created instead of taking away the routes to data centers. It also benefits Remote Office/Branch Office (ROBO) environments and organizations that have a dispersed user base geographically.
Edge computing is a broad term that usually connotes using computers and servers behind the firewall or in other remote locations. However, it also refers to technologies that help enterprises drive digital transformation by automating routine processes and handling new workloads more efficiently.
Key Drivers Accelerating Edge Computing Adoption
The development and acceptance of edge systems are motivated by many factors. Here we look at some of the crucial accelerators in its growth:
AI and Machine Learning at the Edge
Edge AI refers to AI algorithms running on Edge Computing Platforms, processing data locally on IoT devices rather than relying on cloud computing. It is also known as on-device AI. This enables faster response times, especially in applications like object counting, robotics, and real-time monitoring.
For consumer devices such as smart speakers, home surveillance cameras, and autonomous robots, privacy concerns drive the need for Edge AI. Accelerated computing in robotics enables quick decision-making in automation by optimizing processing efficiency at the edge.
Growth of IoT and Connected Devices
With IoT, intelligence moves to the edge. In sensor-intensive environments where large volumes of real-time data are generated, traditional cloud-based approaches fall short. Edge Computing Platforms help optimize power, analytics, and real-time responsiveness by reducing dependency on central cloud servers.
In IoT, edge computing offers benefits such as:
-
Lesser Network Load

-
Enhanced Security and Privacy
Real-time Processing and Low Latency Needs
-
Data and Bandwidth: One of edge computing's motivating drivers' prolific production is the desire to transfer data closer to the edge. The data set has only local importance, or a subset has value in an aggregate, a vast amount of data generated and retrieved.
-
Local Interactivity: Particularly for highly competitive systems, there is a high degree of collaboration or chattiness. Such benefits include unparalleled local interactivity, reduced impact from service interruptions, improved privacy and security, and reduced latency.

Edge Computing Architecture and Core Components
Fig 1: Edge Computing ArchitectureEdge Devices and Edge Nodes
An edge device is a piece of equipment that contains computational and data transmission capabilities, for example, internet routers, IoT sensor devices, smartphones, etc. Most edge computing devices contain a processor, memory, storage, input-output outlets, ethernet port, etc.
Edge devices are connected with peripheral input devices such as cameras and sensors to collect the data and do the processing and analysis of data on-site. The application or script for data processing and analysis is deployed on the edge device. The devices are then connected to a cloud platform or output device to deliver the inference and gathered data.
Some well-known examples of edge devices are - Raspberry Pi, the NVIDIA Jetson series, Lenovo ThinkEdge, etc. Several peripheral devices are specifically made to integrate with edge devices. Pi Cameras are cameras made to work with Raspberry Pi providing high-resolution images and video capture. Intel's RealSense Depth cameras measure the depth of surfaces captured by the camera using stereo vision and sensors.
Edge Servers vs. Cloud Servers
In a cloud-based data center, AI processing is achieved with deep learning models that require immense computational power. And latency is one of the most common problems experienced in a cloud environment or cloud-backed IoT devices. Besides, there is always a chance of data theft or leakage during data transmission to the cloud. Before sending it off to a distant location for further analysis, data is curated with Edge.
In edge-based architecture, inference occurs locally on a computer. With the reaction time for IoT devices reduced to a minimum, this reduces the volume of network traffic streaming back to the server, allowing management choices to be available on-site, next to the devices that provide various benefits.

Edge devices are connected to edge gateways via communication systems such as Bluetooth, ethernet, wi-fi, NFC (near-field communication), Zigbee, etc. These systems provide communication in a range from less than 4cm to up to 100m of distance.
Edge gateways are nodes acting as gateways between the edge device and the core network where heavy data processing occurs. Edge gateways are connected to the core network via communications systems such as LTE-A (Long-term Evolution Advanced) for long-distance communication >1km and Z-wave, Bluetooth Low Energy, etc., for shorter distances up to 100 meters.
Hybrid Cloud and Edge Integration
For enterprises that want to adopt a hybrid cloud strategy, edge devices can be essential in driving digital transformation. They can access the public cloud and connect to the internal data lake for increased collaboration and business insight. Edge devices can also be connected to the edge of the internet, allowing them to access content beyond the firewall.
These edge devices can be either built-in or added to an IT infrastructure. The main advantage of edge computing is that it allows for more agility and efficiency because it is closer to the business end users. It also allows for greater flexibility, as organizations can decide which technologies they want to use, where to deploy them, and how to operate them.
Edge Computing in IoT: Powering Smart Devices
With IoT, intelligence moves to the edge. In highly sensor-intensive or data-intensive environments where data is generated at the edge due to IoT data sensing, traditional approaches don't meet the requirements which are needed.
