Your on-prem cloud integrates with your existing IT environment and can evolve as new workloads emerge and business needs change. This gives you the flexibility to develop your infrastructure at your own pace.
On-prem cloud and housing for large companies
Build a cloud environment with full control over your data and infrastructure
- Keep critical workloads close to your business
- Maintain control over data, security and compliance
- Strengthen your infrastructure with expert operational support
Take charge of your infrastructure strategy
Not every workload belongs in the public cloud. Organisations with business-critical applications often need greater control over security, compliance, performance and data sovereignty. An on-prem cloud approach combines cloud flexibility with dedicated infrastructure, so you can modernize without giving up control.
Why do large companies choose an on-prem cloud?
As data volumes grow and compliance, security, and data sovereignty requirements become more demanding, not every workload belongs in the public cloud. An on-prem cloud platform helps you keep sensitive data close to your business, meet compliance obligations, and reduce dependency on external connectivity, while still benefiting from automation, self-service, and scalable infrastructure.
It also delivers predictable performance and better cost control for critical or latency-sensitive workloads. As cloud pricing and consumption models become more complex, an on-prem cloud approach offers greater cost predictability. Integrated into a hybrid or multi-cloud strategy, it gives you the flexibility to place every workload in the environment that fits best while maintaining a consistent operating model.
How we build your on-prem cloud
At Proximus NXT, we start with your IT environment, workloads and business objectives. Not with a specific technology or vendor. Our cloud experts bring these requirements together in an on-prem cloud architecture that balances performance, flexibility and cost. Our approach is based on three key design principles.
A vendor-neutral approach
We start with your requirements, not with a specific technology or vendor. Our broad ecosystem allows our experts to objectively select the solutions that best fit your environment and strategy.
The right architecture for every workload
Our experts assess your workloads based on performance, security, compliance and operational requirements. From there, we determine the most suitable technology and architecture for each workload.
Optimised total cost of ownership (TCO)
We factor cost into the design from the start, giving you clear visibility of your TCO and helping you avoid unexpected costs later on.

Frequently asked questions
-
An on-prem cloud is a cloud environment that runs on dedicated infrastructure located in your own data center or in a trusted hosting facility. It combines cloud capabilities such as automation, self-service and scalability with greater control over infrastructure, security and data.
-
An on-prem cloud describes where the cloud infrastructure runs, while a private cloud describes how cloud resources are dedicated to a single organisation.
A private cloud can be deployed on-premises, hosted by a service provider or delivered as a managed service. An on-prem cloud is therefore one possible deployment model for a private cloud, but the two terms are not interchangeable.
-
An on-prem cloud is a cloud environment running on dedicated infrastructure, while a hybrid cloud combines multiple cloud environments, such as on-prem, private and public cloud.
Many organisations use an on-prem cloud as part of a broader hybrid cloud strategy, placing each workload in the environment that best meets security, compliance, performance and cost requirements.
-
Workloads that require low latency, predictable performance or strict control over data and infrastructure are often best suited for an on-prem cloud.
Examples include mission-critical business applications, databases containing sensitive information, regulated workloads and systems that depend on existing on-premises infrastructure.
-
Organisations typically choose an on-prem cloud when they need greater control over security, regulatory compliance, data sovereignty or application performance.
It is particularly well suited for business-critical applications, latency-sensitive workloads and organisations that want greater control over their infrastructure while still benefiting from cloud capabilities.
-
Yes, many organisations combine on-prem infrastructure with public cloud as part of a hybrid cloud strategy.
This allows you to keep sensitive workloads on dedicated infrastructure while using public cloud services for scalability, innovation or temporary capacity.
-
It depends on your workload characteristics, performance requirements and operational needs.
For stable, predictable workloads, an on-prem cloud can provide greater cost predictability. Public cloud may be more cost-effective for highly variable workloads or short-term capacity needs. The right deployment model depends on your business objectives and workload profile.
-
Most organisations migrate to an on-prem cloud in phases to reduce operational risk and minimize business disruption.
A successful migration starts with assessing your current applications, infrastructure and business requirements.
Organisations typically prioritize workloads, define the target architecture, validate dependencies and migrate in phases to minimize business disruption. Careful planning helps reduce risk while maintaining business continuity.
-
Most legacy applications can be integrated into an on-prem cloud environment without requiring an immediate replacement.
Rather than replacing existing systems all at once, organisations can modernize their infrastructure in phases. This allows legacy applications to continue running alongside modern cloud platforms, reducing operational risk, minimizing business disruption and protecting previous technology investments.
-
The right platform depends on your workloads, operational model, scalability requirements, existing technology landscape and long-term cloud strategy.
Factors such as virtualisation, automation, integration capabilities, lifecycle management and vendor ecosystem should all be considered before selecting a platform.
-
Backup and disaster recovery should be built into your overall cloud architecture from the start.
Most organisations combine automated backups, replication and disaster recovery plans to protect business-critical workloads and reduce downtime in the event of an incident.
-
An on-prem cloud can help organisations meet regulatory, industry and internal governance requirements by providing greater control over infrastructure, data location and security policies.
The exact compliance framework depends on your industry and applicable regulations. Infrastructure design, operational processes and hosting location all contribute to achieving compliance objectives.
-
Professional housing services provide secure facilities designed to protect critical infrastructure through physical security, redundant power, environmental controls and resilient connectivity.
For organisations without their own data center, housing services offer a reliable foundation for hosting an on-prem cloud while supporting business continuity and operational resilience.
