Frequently asked questions

A private cloud is a dedicated cloud environment used by a single organization. It allows you to run applications, store data and manage infrastructure with full control over security, performance and data location.

In enterprise environments, private cloud is often used to support critical workloads while maintaining strict control over how infrastructure is configured and operated.

Public cloud resources are shared across multiple organizations, while private cloud is dedicated to your business.

Private cloud offers:

  • More control over data and infrastructure
  • Better support for compliance and sovereignty
  • Predictable performance

Public cloud offers:

  • High scalability
  • Lower entry cost

If control and compliance are key, private cloud is often the preferred model.

Private cloud is a strong fit if your organization:

  • Handles sensitive or regulated data
  • Needs full control over infrastructure
  • Must comply with European regulations
  • Runs critical or legacy applications
  • Requires predictable performance

Private cloud helps enterprises:

  • Keep full control over data and infrastructure
  • Meet compliance and data sovereignty requirements
  • Improve security and risk management
  • Ensure high availability and performance
  • Scale resources based on business needs

Private cloud offers greater control over security because:

  • Infrastructure is dedicated to your organization
  • Security policies are fully configurable
  • Data location is known and controlled

Security also depends on how the environment is managed, monitored and updated over time.

Private cloud allows organizations to store and process data in specific locations, such as Belgium or the EU.

This helps meet:

  • GDPR requirements
  • Local data residency laws
  • Industry regulations

Working with a local provider such as Proximus NXT can help ensure data remains within the required geographic boundaries.

In a self-managed private cloud (like Business Cloud), your internal IT team manages the infrastructure and operations.

In a managed private cloud (like U-Flex), a provider takes care of:

  • Infrastructure management
  • Monitoring and maintenance
  • Security and updates

Choosing between both depends on how much control and operational responsibility you want to retain.

Private cloud costs depend on:

  • Infrastructure size (compute, storage, network)
  • Level of management (self-managed vs managed)
  • Security and compliance requirements

Flexible pricing models, such as subscription or usage-based consumption, help keep costs predictable and aligned with business needs.

For a tailored estimate, it is often useful to discuss your setup with a cloud expert.
