IoT vs. Edge Computing

Introduction: IoT vs. Edge Computing. I see the terms Internet of Things and Edge Computing everywhere I examine the Internet today. At first glance, these terms seem synonymous because they are often deployed in the same infrastructure. If you look closely, however, you’ll realize they’re worlds apart.

Both IoT and Edge represent a paradigm shift in data collection and analysis. These technologies also transform the objects you use every day into ‘smart’ devices. Clocks watches, and other household devices can transfer data to another device/storage. Of course, this multi-device connection opens up a world of opportunities.

IoT vs. Edge Computing

IoT devices are equipped with sensors that make them “smart.” These sensors collect information resulting in large amounts of data. An Internet of Things (IoT) gateway acts as a router and sends data to the cloud via many data protocols, such as HTTP and MQTT (MQ Telemetry Transport).

Once the data reaches the cloud, analytics tools process the data and extract key insights. This information is then sent back to the end user through an API.

This article will help to understand the differences between IoT and edge computing.

What is IoT (Internet of Things)? 

The Internet of Things (IoT) is a system of corresponding physical, digital, mechanical, and computing devices or “things” that are embedded with unique identifiers (UIDs) that allow them to communicate with each other over the Internet. These devices run the gamut from standard items to sophisticated devices.

What is Edge Computing?

 The growing adoption of IoT is indeed a powerful driver for edge computing. As more and more IoT devices become connected, they will generate a lot more data. But transmitting all this data to the cloud for processing can be harmful.

First, the costs of sending each piece of data to the cloud can be prohibitive. Second, transmitting much data to the cloud can cause latency and bandwidth issues. Edge computing pushes data processing nearer to the actual location (sensor devices) rather than sending it to centralized cloud thousands of miles away.

This is especially important where data is time-sensitive and split-second decisions must be made. Edge devices perform advanced analytics on information available at the network’s edge and provide organizations with much-needed predictions and solutions in real-time.

IoT vs. Edge Computing: Understanding the Differences between IoT and Edge Computing

Rapid technological advancements have given rise to transformative concepts such as the Internet of Things (IoT) and edge computing. While IoT and edge computing play pivotal roles in shaping the future of connected systems, they serve distinct purposes and possess unique characteristics.

IoT and edge computing are different technologies that work together to make our daily lives easier. IoT devices are like physical objects that transmit real-time data to the network, while edge computing brings data or information processing closer to the IoT devices. IoT and the edge symbolize a paradigm modification in data accumulation and examination.

Edge computing works with many other prominent technologies, including the Internet of Things. Therefore, they are complementary technologies that depend on each other to maximize benefits to individuals and businesses.

The Internet of Things (IoT) is an extensive web of interconnected devices, sensors, and objects that can organize and exchange data over the Internet. It enables seamless communication and data sharing among various devices, allowing them to interact and make informed decisions. The primary goal of IoT is to create an innovative and interconnected world by enabling devices to connect, communicate, and collaborate.

On the other side, edge computing is a distributed computing paradigm that brings computing resources and data storage closer to the source of data generation. It aims to minimize latency, bandwidth usage, and reliance on the cloud by processing data locally on edge devices. Edge computing facilitates real-time data analysis, reduces network congestion, and enhances overall system performance.

One fundamental distinction between IoT and edge computing lies in their focus areas. IoT primarily deals with the connectivity and communication aspects of the network, emphasizing the interconnectivity of devices and the seamless flow of data.

In contrast, edge computing focuses on processing and analyzing data at the network’s edge, near the data source, to reduce latency and improve response time.

In terms of architecture, IoT typically involves a centralized structure where data from multiple devices is collected and transmitted to a central server or cloud platform for processing and analysis. This centralized approach enables scalability and easy management of large-scale IoT deployments.

In contrast, edge computing emphasizes a decentralized architecture, where data processing and analysis occur on edge devices, eliminating the need for constant reliance on a central server or cloud infrastructure.

Furthermore, IoT and edge computing differ regarding data processing and storage capabilities. IoT devices are often resource-constrained, with limited processing power and storage capacity. Consequently, they rely on cloud infrastructure to perform complex computations and store large volumes of data.

In contrast, edge devices in an edge computing ecosystem possess more computational power and storage capabilities, enabling them to perform real-time analytics and store critical data locally.

Despite their differences, IoT and edge computing are not mutually exclusive. They complement each other and can be leveraged together to achieve optimal results. Edge computing is a vital component of the IoT ecosystem by enabling real-time data processing and analysis, reducing latency, and ensuring local autonomy. It enhances IoT applications that require real-time decision-making, such as autonomous vehicles, smart cities, and industrial automation.

By leveraging edge computing, IoT systems can offload computationally intensive tasks to edge devices, minimizing the need for constant communication with the cloud.

This approach reduces network congestion and enhances data privacy and security since sensitive information can be processed and stored locally. Furthermore, edge computing allows IoT systems to function even without a stable internet connection, ensuring uninterrupted operations.


In conclusion, IoT and edge computing serve different purposes but are intricately connected and have overlapping benefits. IoT enables seamless connectivity and communication among devices, while edge computing focuses on real-time data processing and analysis at the network’s edge.

The difference between IoT and edge computing leads to improved system performance, reduced latency, and enhanced security, enabling sophisticated IoT applications to be realized. As technology continues to evolve, the collaboration between IoT and edge computing will play a vital role in shaping the future of interconnected systems.
