Significant, industry-wide investment in edge computing will change the profile of the data centre ecosystem over the next five years, increasing the edge component of total compute by 29 per cent over that time. The magnitude of the industry’s ongoing shift to the edge is among the notable findings from a new global survey of data centre industry professionals from Vertiv, a global provider of critical digital infrastructure and continuity solutions.
Vertiv surveyed 156 industry professionals with insight into their company’s edge computing plans. About a third (34 per cent) of those surveyed are either planning or in the midst of significant edge deployments. A quarter already have deployed new, purpose-built edge sites, and 41 per cent are operating legacy edge sites. All the activity at the edge is striking, but survey participants also anticipate a 150 per cent increase in core sites and increased activity in the cloud. According to the survey, the percentage of IT resources deployed in the public cloud is expected to grow from 19 per cent currently to 25 per cent by 2026. The demand for computing resources is skyrocketing across today’s networks.
Commenting on the study, Martin Olsen, global vice president for edge strategy and transformation, Vertiv, said, “The next five years will reshape the data centre landscape, shifting more and more computing to the edge while buttressing the enterprise facilities at the core of modern hybrid networks. This survey makes clear the urgent demand for computing closer to the end user. The future of computing is about speed and latency, and the only way to meet the need is to build out the edge of the network.”
The survey results arrive on the heels of the release late last year of Edge Archetypes 2.0: Deployment-Ready Edge Infrastructure Models. That report furthered Vertiv’s research into the edge of the network and identified four edge infrastructure models that enable a more intelligent, semi-standardized approach to edge infrastructure deployment. The survey results are consistent with the premise of Edge Archetypes 2.0 – that massive growth at the edge necessitates a more standardized approach to edge architecture.
The survey also revealed the changing profile of the modern edge site. Twenty-nine percent of sites feature between 5 and 20 racks, and 13 per cent have more than 20 racks. More racks mean more power, and the survey results reflect that: 28 per cent say their sites require between 21 and 200 kW, and 14 per cent report power demands in excess of 200 kW. The days of single racks tucked away in rudimentary IT closets are over.
Other significant findings from the survey included:
- Sustainability is playing a major role in new and planned edge deployments. More than three-quarters of sites (77 per cent) are using or planning to use energy-efficient UPS systems. In addition, 40 per cent are planning to use renewable energy; 31 per cent water-efficient cooling; 29 per cent dynamic grid support technologies; and 19 per cent refrigerants with a low global warming potential (GWP).
- While security and availability were top priorities of participants deploying edge sites, the survey exposed some current design and operating practices that could reduce edge computing site’s ability to achieve these objectives as the number of sites expands.
Meanwhile, Dr AS Prasad, general manager, Integrated Rack Solutions – India, Southeast Asia, Australia, Japan and Korea, Vertiv, said, “With the increase in adoption of emerging technologies like Internet of Things, Machine Learning, Artificial Intelligence and 5G networks, the need for data centres to reduce latency and process data real-time has become critical. As a result, bringing computing capabilities closer to the consumer has become essential to help businesses understand their customers and alter their strategies on-the-go. Vertiv’s new global survey highlights the growing focus on edge computing and how businesses are changing their digital strategies to support the future of edge use cases.”
