Edge Computing: The Next Frontier in Information Technology


Edge computing is a rising computing concept that involves networks and devices located near the user. It focuses on processing data in close proximity to where it is generated. This approach enables faster and larger-scale data processing, resulting in real-time actions and more impactful outcomes. In our fast-paced world, we’re producing an enormous amount of data every day. To keep up with this data overload and the need for quick processing, traditional cloud computing systems are struggling. That’s where edge computing comes in. It’s a new approach that brings computing power closer to where the data is created. By doing this, edge computing can make things faster, reduce delays, and improve security.


Edge computing is an alternative computing infrastructure that moves data processing and analysis closer to where the data is generated, known as the “edge” of the network. Unlike traditional cloud computing approaches that involve sending data to a centralized server, edge computing distributes computational resources near the end-users and devices. This decentralized setup significantly reduces latency and greatly improves real-time capabilities.


The main benefit of edge computing is easy to see: it enhances the user experience by making things more relevant at the edge. Furthermore, edge computing unleashes the potential of valuable data, paving the way for new opportunities and innovations in the future. With an increased number of sensors generating more data, processing that data at the source becomes faster, more reliable, and safer. When combined with insights from the cloud, the system produces improved predictions and more pertinent information, creating a cycle of ongoing enhancement.

By bringing computational power to the edge, edge computing offers several advantages over traditional cloud computing models. The proximity to data sources allows for faster processing and analysis, as there is no longer a need to send data over long distances. This reduction in latency enables real-time responsiveness, making edge computing suitable for time-sensitive applications such as autonomous vehicles, industrial automation, and other systems that require instantaneous decision-making.

Utilizing other technologies


5G technology plays a vital role in enabling seamless edge implementations by ensuring the reliable transmission of crucial control messages. These messages enable devices to make independent decisions, empowering them with autonomy. Acting as a last-mile connection, 5G links the edge to the internet backhaul, guaranteeing that edge devices possess the necessary software-defined network configurations to perform their intended functions.


The Internet of Things (IoT) and connected devices serve as unique data sources that require secure registration in the cloud. The edge, in this context, resides in close proximity or directly on these data sources, facilitating efficient data processing and analysis.

Service and Data Mesh

Service and data mesh provide a mechanism to deploy and access distributed data and services across containers and data stores within the edge infrastructure. These meshes present a unified interface that abstracts the complexities of routing and managing services and data interfaces. This capability allows for bulk queries across the entire edge population, eliminating the need to query each individual device.

Software-defined Networking

Software-defined networking enables users to configure overlay networks and facilitates customizable routing and bandwidth allocation. It streamlines the process of connecting edge devices to one another and to the cloud, providing flexibility and control over network configurations.

Digital Twin Technology

Digital twin technology acts as a crucial facilitator by bridging the physical-to-digital and cloud-to-edge divide. It enables the organization and configuration of data and applications using domain-specific terms related to assets and production lines, rather than relying solely on database tables and message streams. Digital twins empower domain experts to configure applications for sensing, processing information, and taking actions at the edge, without requiring extensive software engineering expertise.


Edge device

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. Few well-known examples of edge devices are – Raspberry Pi, the NVIDIA Jetson series, etc.

Cloud platforms

Most well-known Edge device toolkit providers also integrate cloud services with Edge. Cloud platforms allow developers and users to interact with edge devices, providing user-friendly interfaces. They are used to monitor the edge devices, update applications deployed on Edge, receive the inference or data gathered by Edge, etc.

Edge Network

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.


Lack of a shared architectural foundation: Setting up edge computing requires the right infrastructure, including cloud providers, networks, and devices. However, many enterprises use multiple incompatible technology stacks that need to be aligned for optimal edge performance.

Rapidly changing landscape with a wide variety of technological choices: The landscape of potential partners and technologies for edge computing is vast, making it challenging to make critical decisions. Ongoing innovation in network capabilities like Multi-access Edge Computing (MEC) and 5G further complicates the decision-making process.

Unexploited business opportunities at the edge: Organizations may struggle to fully grasp the business value that can be unlocked through edge solutions. It is essential to move beyond simple use cases with quick returns and instead invest in desirable, feasible, and viable experiences for edge computing that provide sustained Return on Investment (ROI).

Scarcity of cloud talent with the skills and experience to manage edge infrastructure: Leveraging the edge is not about completely retooling, especially for companies already utilizing the cloud. It involves extending existing cloud capabilities to the edge. Organizations can utilize their existing cloud talent to deploy edge solutions, with the hardware connection being the simpler aspect.

Particular security risks posed by edge networks: Security must seamlessly extend from the cloud to all edge instances. However, security in the IoT and edge domain differs significantly from security in the traditional IT domain. Edge environments involve time-critical, safety-critical, and autonomous operations. Security models must consider the long design life and legacy infrastructure of edge devices. Additionally, devices may be located remotely or in untrusted environments, requiring a combination of cyber and physical defenses. The heterogeneity of hardware, software, and network combinations further complicates the rollout of security updates.

Despite these challenges, edge computing is a promising technology with the potential to revolutionize the way we interact with the world around us. As the volume and velocity of data continues to grow, edge computing will become increasingly important for businesses and organizations that need to process data in real time. Overall, the future of edge computing is bright. Edge computing offers a number of advantages over traditional cloud computing models, and it is well-positioned to meet the needs of businesses and organizations in the future.
