In this extended blog, Joachim van Collenburg (VP Enabling Services at nLighten) and the BDIA address the advantages of implementing a hybrid data center strategy into your organization.
Mid-market tech companies are at the heart of digital innovation but face growing demands for computing power as they scale. Many begin with an on-premises IT infrastructure, which serves well in the early stages. However, as operations expand, relying solely on on-site hardware and software limits agility and performance. At this point, businesses often transition their IT infrastructure to external providers.
Before edge computing, companies traditionally relied on one large, centralised hyperscale data center, typically located in one of the FLAP-D core hubs (Frankfurt, London, Amsterdam, Paris, and Dublin). If additional data centers were used, it would mainly be for fallback or disaster recovery. However, the traditional model reveals its limits as the need for real-time processing increases. Centralised infrastructure struggles with latency and scalability, while the OPEX-driven cost structure comes from using cloud services, where operational expenses rise in line with growth, has become a significant bottleneck, prompting a shift in strategy.
Scalable IT environment
Although hyperscale data centers and cloud infrastructure continue to offer reliability and connectivity, they are no longer sufficient in a world that increasingly relies on low-latency applications and the efficient processing of data near its source. The rise of edge data centers enables a more flexible, hybrid approach, balancing the strengths of centralised hubs with the advantages of infrastructure located closer to end users. Incorporating edge data centers into the IT mix allows companies to improve performance for latency-sensitive applications, especially in sectors like financial services, healthcare, and AI, where milliseconds matter. Instead of choosing between centralised or distributed infrastructure, mid-market companies can create a scalable IT environment that allocates workloads dynamically based on performance, cost, and sustainability needs.
This shift toward more scalability is not only strategic—it’s being mirrored in the evolution of national markets. For example, Belgium’s data center market is rapidly growing into a key European hub, thanks to a combination of geographic advantages, regulatory pressures, and a wave of AI-driven infrastructure investment. This makes Belgium increasingly relevant for mid-market firms looking to leverage both local and regional infrastructure in a hybrid setup.
Advantages of a hybrid data center strategy
One of the key advantages of a hybrid data center strategy is its ability to support growth with agility. While centralised data centers provide scale, combining them with edge facilities enables smarter resource distribution. Core workloads remain in central hubs, while latency-sensitive or localised tasks are handled at the edge. Facilities like nLighten allow workloads that do not require continuous operation to run under metered power regimes—reducing energy costs and supporting sustainability goals. In contrast, many hyperscale data centers do not offer such flexible power models, making hybrid approaches increasingly valuable.
The importance of sector coupling
Beyond operational efficiency, a hybrid strategy supports long-term environmental goals—a key factor in modern IT decision-making. A well-designed model enhances energy performance by minimising transmission losses and leveraging localised power strategies. Edge data centers can tap into regional energy markets, align with local grid conditions, and benefit from time-based or metered pricing. Sector coupling initiatives go further by integrating with municipal systems, enabling energy recovery—for example, redirecting excess heat to nearby communities to replace carbon-intensive heating like natural gas. Moreover, on-site renewable sources such as solar, wind, biogas, or hydrogen reduce emissions and support grid resilience. Collectively, these practices contribute to corporate sustainability while improving operational resilience.
Related to that, Belgium is aligning with these goals through proactive sustainability regulation. The new European Energy Efficiency Directive (EED) now requires mandatory reporting for data centers over 500 kW, pushing transparency in energy usage, water consumption, and heat reuse. Many operators in Belgium have joined the Climate Neutral Data Centre Pact, showing industry-wide commitment to greener operations.
Hybrid infrastructure offers the flexibility to deploy workloads
Finally, as AI becomes central to business operations, hybrid infrastructure offers the flexibility to deploy workloads where they are most effective. AI inference, which requires low latency and real-time processing, benefits from edge data centers close to end users. Meanwhile, AI training—demanding vast computing resources—is better suited to centralised data centers. This strategic distribution helps mid-market companies manage costs, maximise performance, and scale AI capabilities effectively.
For mid-sized tech firms aiming to grow, a hybrid infrastructure—combining centralised and edge data centers—offers the flexibility, efficiency, and scalability to thrive. As digital transformation continues and new European markets like Belgium open up new hybrid possibilities, this balanced strategy positions companies to adapt to shifting demands and remain competitive in a fast-evolving, data-driven world.
