Rumours of private cloud’s demise have been greatly exaggerated. In this blog we’ll share six reasons why private cloud is still relevant in 2025 – and explain why Six Degrees’ Private Cloud is best placed to sit at the heart of your business’ hybrid cloud strategy.
With the significant growth public cloud is experiencing, some would be forgiven for assuming private cloud is being edged out of businesses’ infrastructure journeys. The benefits of public cloud are certainly compelling, but the reality we see on the ground is that private cloud is actually experiencing a renaissance in 2025.
Why is this? Well, to understand why private cloud is still relevant in 2025 we need to start by defining what a private cloud is – and how it can combine with public cloud to form the hybrid clouds that we believe will be the preferred infrastructure choice for many if not most moving forward.
Private vs Public vs Hybrid Cloud – What’s the Difference?
When we talk about the different cloud types, here’s how we define them at a high level:
- Private clouds like Six Degrees’ Enterprise Cloud provide hosting through either a virtual model, with shared infrastructure and a defined contention ratio, or a dedicated model, with dedicated infrastructure, compute, storage and uncontended options.
- Public clouds like Microsoft Azure provide hosting with all hardware, software, and supporting infrastructure owned and managed by the cloud provider. All resources are shared and businesses – often called ‘tenants’ – access services through a web browser.
- Hybrid clouds combine private and public cloud services, enabling businesses to leverage the benefits of both. Hybrid cloud is distinct from multi-cloud, which is the combination of multiple public cloud platforms (for example Microsoft Azure, Amazon Web Services, and Google Cloud Platform).
Six Reasons Private Cloud is Still Relevant in 2025
At Six Degrees we work with businesses across many industries who are re-evaluating their cloud strategies to ensure security, compliance, and cost control. Here are six reasons why private cloud is still relevant in 2025:
- Regulatory Compliance and Data Sovereignty
Many industries have strict regulatory requirements that public cloud alone cannot always meet. Regulations like GDPR, FCA guidelines, and industry-specific compliance mandates make data sovereignty a top priority for UK businesses. Where your data resides isn’t just a technical detail, it’s a legal and regulatory requirement.
At Six Degrees our UK sovereign Enterprise Cloud means you retain full control over data location and access and compliance with UK and EU data protection laws, ensuring no risk of foreign jurisdiction interference.
- Performance and Uptime
Private cloud offers dedicated resources with guaranteed performance, reducing latency issues in multi-tenant public environments. It’s an unfortunate fixture of public cloud environments that given their scale and complexity outages can happen – and those outages can be significant.
Six Degrees’ Enterprise Cloud is fully owned and managed by us, and we give our tenants complete control over their contention ratio, compute, and storage. When you host in the Enterprise Cloud you benefit from performance and predictability that aligns to your business’ needs.
- Cost Control and Predictability
With rising public cloud costs, many businesses are seeking cost-efficient alternatives that provide fixed pricing models. We’ve seen businesses stung by unexpected costs after moving to public cloud – private cloud offers the cost control and predictability that gives confidence that the risk of unexpected costs will be mitigated.
The Six Degrees Enterprise Cloud offers cost predictability relative to other cloud platforms, and our flexible commercial models open up the cloud to CAPEX-centric organisations.
- Hybrid Cloud Integration
When it comes to cloud there’s never a simple a one size fits all. Many businesses choosing between public and private cloud platforms feel the need to compromise with trade-offs in experience, simplicity, and quality of service.
Fortunately, there is another way. Hybrid Cloud services from Six Degrees remove the trade-offs of choosing between public and private cloud services, delivering the best of both worlds while offering a single, unified experience.
- Security and Risk Mitigation
Private cloud provides greater control over security, data governance, and infrastructure customisation than standardised public cloud offerings. As a result, security is often the most significant deciding factor when choosing private cloud.
However, technology alone isn’t enough; businesses need the right security expertise and operational support to protect their data effectively. At Six Degrees our end-to-end cyber security services ensure your private cloud forms part of a robust, holistic cyber security posture.
- Cloud Readiness
For many cloud-native workloads, public cloud is an optimal location – but what about traditional non-cloud native workloads that aren’t ready for public cloud?
The Six Degrees Enterprise Cloud enables you to virtualise traditional non-cloud native workloads either permanently or as part of a phased transition to public cloud.
Private Cloud Isn’t Just Relevant in 2025 – It’s Essential
At Six Degrees we believe the future of cloud is hybrid – and that business’ focus should be on hosting each workload in the optimal cloud, with a unified management wrap to ensure control, security, and compliance.
In a hybrid cloud world, private cloud isn’t just relevant in 2025 – it’s essential. Six Degrees is well placed to deliver private cloud hosting as part of a holistic offering that includes:
- UK-sovereign Enterprise Cloud – keeping data safe, compliant, and in UK jurisdiction.
- Cyber security consultancy – providing expert guidance on securing cloud environments.
