A real private cloud.
"Private cloud" is often understood purely as the counterpart to "on-premise". But a real private cloud doesn't necessarily mean your hardware has to sit in a third-party data center. A private cloud can also be realized on-premise, running on your own existing hardware (investment protection).
Rather, in direct comparison, it's about a modern operating model: you hand off the complex management of an infrastructure platform and consume it under fixed service level agreements (SLAs) – on dedicated hardware, exactly where it makes the most sense for you.
No vendor lock-in (KILL switch)
Complete documentation and open standards guarantee your independence.
Fixed SLAs
Contractual availability guarantees and guaranteed services for operations.
Data sovereignty
Full control over data location and transparent hardware usage.
Legal certainty
Clear jurisdiction, no influence from the US CLOUD Act.
SCS Standard
The core principle of the infra:u Private Cloud Stack
The core principle of our infra:u Private Cloud Stack (based on the Sovereign Cloud Standards / SCS) is to outsource operational responsibility for the software layer without giving up sovereignty:
Flexible to your requirements
The operating models
Since your own hardware can continue to be used, the classic CapEx vs. OpEx comparison often falls short here. Depending on whether you want to use your own premises and hardware or outsource everything, we offer different models.
Software & Service
Private Cloud Stack
You provide the location (your server room – in your own data center or with a colocation partner of your choice), the connectivity, and your own hardware. UPONU takes care of platform management, monitoring, and patch management of the cloud stack on your devices.
Software, Service & Hardware Private Cloud Stack
You provide only the location and connectivity (e.g. a colocation space). UPONU supplies the dedicated hardware and takes over the complete operation of the cloud stack built on top of it. Implementation time for new projects and resources drops drastically, since hardware lifecycles are managed by us.
Hosted Private
Cloud Stack
The all-inclusive model. Location, connectivity, dedicated hardware, and the entire platform management are provided entirely by UPONU in our highly secure data centers (with excellent data security).
Shared Cloud Stack resources run on hardware shared across UPONU data centers. Suitable for web hosting or workloads that don't require exclusive hardware but need the sovereignty of our cloud.
Scope and services of the cloud stack
Operating a powerful infrastructure platform is demanding. The infra:u Private Cloud Stack takes this complexity off your hands. Our service offering includes:
- Provisioning & updates: Initial installation and updates of the OpenStack (SCS) platform
- Patch management: Proactive review and rollout of software updates
- Administration: Ongoing monitoring, control, and optimization of the systems
- Monitoring: 24/7 real-time monitoring for early detection of bottlenecks
- Migration support & project management: Structured transition to the new environment, including proof-of-concept and readiness check
- 24/7 hotline: Direct access to our in-house data center expert team
- Optional add-ons: Veeam Recovery, the crypto gateway mail:u secure, or billing:u
Companies and operators face the challenge of setting up their IT infrastructure securely, maintainably, and cost-efficiently while ensuring reliable operations. Moving to a service provider with a dedicated cloud infrastructure is the logical consequence for many workloads. Especially with the large international hyperscalers, however, there's always the risk of a creeping loss of control: opaque cost structures, dependency on proprietary interfaces, and ongoing uncertainty regarding data sovereignty (for example due to the "US CLOUD Act").
The infra:u Private Cloud Stack is the sovereign alternative for strategic IT outsourcing: we offer a private cloud solution that provides data sovereignty by design, not as an afterthought. You get scalable compute power, reliably, transparently, and without the vendor lock-in of proprietary solutions.
FAQ
Frequently asked questions
Looking at Total Cost of Ownership (TCO), the cloud often scores through better predictability and the absence of massive upfront hardware investments (CapEx). Since the infra:u Private Cloud Stack can also run on your existing on-premise hardware, previous investments are protected and can be transitioned smoothly into an OpEx model.
Generally, yes. Professional cloud providers invest in data security, redundant infrastructure, and modern network defenses at a level that is often difficult to finance for a classic on-premise server room.
A private cloud consists of hardware reserved exclusively for one company. A VPC is an isolated, private network within a larger cloud infrastructure. Both models aim for maximum logical separation and data security.
Yes, that's common practice. Many companies keep legacy systems on-premise and securely connect them to their private cloud, where modern workloads run.
