Public cloud was once considered the go-to option for modernising IT, but unpredictable costs and a lack of clarity on data sovereignty call for new approaches. Modern hyper-converged infrastructures (HCI) now enable a hybrid strategy that radically reduces computing power and offers the control over workloads that organisations need to achieve a balance between operational simplicity, predictable costs and resilience – without sacrificing the cloud’s convenience. And while this challenge has been widely addressed for corporates, this is also an issue that SMEs should pay careful attention to.
A recent survey estimated that up to 80% of the UK’s SMEs faced unexpected cloud costs. While this figure does not break down cloud type, it is widely known that hyperscalers excel at global scaling and reach, but often disappoint with spiralling costs and data sovereignty provision. So for a small law firm wanting to assure data residency and compliance for its clients, or an education establishment under pressure to manage costs, hyperscale services may not be best suited.
A solution to this lies not in a complete retreat from the cloud, but in technological precision. Thanks to 3nm chips and modern HCI, the power of entire server rooms can now be condensed to the size of a milk carton. This ‘invisible’ infrastructure affords the choice of both cloud and on-premise options, allowing SMEs to place workloads exactly where they make the most technical and commercial sense.
The shrinking enterprise data centre
Whilst cloud data centres are becoming ever more colossal in terms of both space and power – in the UK, the Next Generation Data Centre provides 250MW of customer power over 750,000 square feet of space, for example – data centres directly belonging to the individual enterprise are shrinking.
The process started with server virtualisation, which consolidated a large proportion of the hardware. Next came the cloud and hybrid cloud wave, which offloaded mass storage and non-critical computing power to hyperscalers, effectively halving the on-premises footprint. The third wave, hyperconverged infrastructure (HCI), completed the process by dissolving the traditional silos of SAN storage, networking and computing power into a single, unified enclosure.
This sets the context for what is happening today; the miniaturisation of the business data centre.
Convenience at a cost?
In recent years, many SMEs have relied heavily on cloud computing, often trading sheer convenience with autonomy. Now SMEs are now painfully realising that pure cloud strategies do not always deliver the predictability they were promised, nor do costs always stay manageable, especially with the need for infrastructure flexibility.
For example, a regional outage affecting a hyperscaler can completely paralyse a company with 100 employees. And beyond availability, the financial reality is becoming clear: the costs of cloud computing are rising continuously and are often unpredictable. For an SME this could feel like a ransom demand for its very own data.
At the same time, the lack of assurance on data sovereignty is making it increasingly difficult to meet strict compliance and data protection requirements in Europe. The answer is not retreat, but technological precision: a new generation of mini-HCI systems restores the sovereignty lost in the first phase of cloud adoption as they are able to provide precision on data residency at a local and more granular level.
Public cloud still needs hardware
Public cloud was once sold – and purchased – as the ultimate modernisation measure: a clear, logical step away from owning hardware. This led to misunderstanding at board-level that a cloud-only strategy meant that no infrastructure purchase was required at all. But this is not the case. Even the most ambitious cloud strategy has a minimal requirement for on-premises hardware to bridge the gap between the user and the hyperscaler.
To maintain high-availability connectivity and security, an SME must continue to manage a 6U to 12U rack containing WAN gateways for VPN and firewalls, PoE switches to power the office, and a fleet of Wi-Fi 6E access points for more than 200 simultaneously connected devices. This shadow infrastructure must then be supported by cooling, power protection and active management.
Why Broadcom is driving change
Whilst hardware has become more compact, the software stacks powering these devices have matured and become more diverse. For years, VMware was the undisputed standard for the virtualisation layer in HCI, by providing a reliable, albeit increasingly expensive, foundation.
Following the takeover by Broadcom, sharply rising licence costs and changing business models have prompted a reassessment. SMEs in particular are now looking beyond the established providers for alternatives that not only offer better value for money, but also a more stable and trustworthy long-term partnership.
In the UK, many SMEs rely on managed service providers (MSPs) to advise on and run distributed IT environments for them. And no matter what the industry sector, MSPs play a crucial partnership role in recommending the most effective infrastructure choice to suit individual business needs.
Whether it is the rise of KVM-based open-source hypervisors or lightweight, specialised stacks for edge orchestration, the focus has shifted to software that is just as agile and cost-effective as the palm-sized hardware on which it runs.
A turning point for SMEs
The miniaturisation of the data centre marks a pivotal opportunity for SMEs. Technological developments in 3nm chips and NVMe storage have finally banished the former spectre of the ‘humming server room’, and have opened up a broader choice of infrastructure options that previously were more accessible to corporates.
For SMEs, HCI today means liberation from the binary choice between cloud dependency and infrastructure chaos. By replacing the ‘shadow infrastructure’ on their office shelves with intelligent, software-defined systems, companies can regain control over their data and costs.
In an era of unpredictable cloud pricing and pressure to comply with data residency legislation, SMEs must harness their IT infrastructure to deliver on the business outcomes they need most. Whether this is cost control, data compliance, simplifying operations or resilience, the 2026 state-of-the-art data centre is no longer an anonymous server farm in the distance – it is compact, quiet, controlled and highly versatile, and all based right from the office.
