Ultra-low latency and real-time processing are now essential for modern enterprises, surpassing the capabilities of centralized cloud solutions. As AI, predictive maintenance, and smart devices grow, CIOs shift to edge-first infrastructure. Gartner forecasts that by 2025, three-quarters of enterprise data will be handled at the edge.
Industries like manufacturing, healthcare, and retail use edge nodes as mini data centers for faster decisions, better data sovereignty, and cost savings. IDC predicts global edge spending will reach $317 billion by 2026. While challenges remain, the benefits, such as secure distributed systems and large-scale data handling are clear. With 5G and IoT spreading, edge computing is not optional. CIOs must balance cloud and edge to keep key data and decisions close.

What Does Edge Computing Refer to?
Edge computing enables data processing and storage closer to its source, allowing immediate processing rather than distant handling. This includes micro data centres in retail and AI-driven equipment in factories. The aim is to accelerate data movement for faster decision-making and improved customer service.
Why is this Shift Happening?
CIOs still depend on the cloud but seek alternative solutions that address its limitations. Cloud systems often experience delays in real-time tasks, while edge computing offers rapid responses in milliseconds. Regularly sharing large data volumes with the cloud can be impractical and costly. Many industries must adhere to strict data processing and storage regulations, which edge computing supports. In the event of network issues, edge infrastructure ensures essential functions continue. Gartner predicts that, by 2025, 75% of companies’ data will be managed at the edge, up from 10% in 2018.
Improving the Experience for Customers
Edge computing enables smart retail by processing data from various sensors and devices. Imagine shelves that automatically update counts or checkout counters that recognise regular shoppers.
Walmart has established edge computing hubs at many stores to improve in-store operations. These hubs monitor everything from cooling systems to price changes without a central data centre.
This technology enhances smart devices and creates personalised experiences. Near-instant processing of customer behaviour and successful sales allows companies to improve stock control and customer service.
Real-time Optimisation in Manufacturing
Edge computing’s role is vital in manufacturing in terms of automation, checking for faults, and quality control. With edge-powered robotics and sensors, performance data is analysed promptly, any problems are noticed as soon as possible, and the systems can react without depending on the cloud’s response time.
Using edge devices in its equipment, Siemens has improved machine availability and reduced upkeep expenses. When a machine starts to wear out, sensors immediately notice it and make repairs before it fails.
With this local insight, manufacturers can work more efficiently and minimise delays, which matters greatly in just-in-time production, where even a little delay can cause huge issues.
Thanks to Edge in Telecom, Technologies Like 5G are Possible
Telecom companies depend on edge computing to successfully introduce and increase their 5G services. Real-time uses, such as augmented reality, self-driving vehicles, and city infrastructure, operate best when edge computing is applied.
Verizon and Vodafone are putting mini data centres at the bottom of cell towers to bring computing and data closer to end users. Decentralisation increases the network’s performance, providing new services to companies.
Edge also plays a key role in network function virtualisation (NFV) and software-defined networking (SDN), where operators need real-time orchestration and provisioning.
What is Changing for the CIO
As businesses embrace more dynamic IT environments, hybrid infrastructure has emerged as the backbone—seamlessly blending cloud, edge, and on-premise systems to meet the growing need for speed, flexibility, and localized processing. But with this interconnectedness comes complexity. Edge devices, while powerful, also expand the attack surface, making them attractive targets for cyber threats. That’s why CIOs are now placing stronger emphasis on endpoint security, robust encryption, and zero-trust frameworks to safeguard their digital ecosystems. At the same time, data lifecycle management becomes critical—deciding what data should be processed on the edge, what must be sent to the cloud, and what can simply be discarded. Given the diversity of edge environments and hardware, interoperability across vendors and platforms is no longer a nice-to-have; it’s essential for building resilient, future-ready tech foundations.
McKinsey & Company emphasize that choosing edge-first strategies allows CIOs to improve their operations by 30% and make noticeable advances in customer service.
Issues that Affect the Realm
Nevertheless, using edge computing involves dealing with various complexities. Management of many edge nodes spread across the network requires much effort and resources. Additionally, there is a lack of skilled professionals who are experts in edge architectures, mainly in AI and IoT. On the other side, initial hardware, protection, and tools costs for running applications may be very high.
Even so, most CIOs consider these setbacks as only temporary changes in the long-term progress of IT infrastructure. The results of being agile, performing well, and coping well are greater than any teething challenges.
Edge is Inevitable
Edge computing has staying power and will not disappear. It plays a key role in modern growth and operation. CIOs must lead the way by outlining a plan that follows business goals, necessary industry changes, and technological progress.
Edge is taking on the role of becoming the new cloud by providing what the cloud didn’t have. Using edge-first architectures, businesses can enhance real-time intelligence, run more efficiently, and prepare for future changes.
Modernising IT activities and preparing for the upcoming digital transformation are what forward-thinking CIOs can achieve by accepting this trend.
