„Control does not come from a server standing in your own data centre, it comes from the operating model behind it: traceable access, documented configuration, reproducible recovery. That can often be better met in a leased European facility than in your own basement.“
- Former CTO idealo: Nearly nine years, 2016 to 2025.
- CIO of the Year 2014: Mid-market category, awarded by IDG, CIO-Magazin and Computerwoche. As VP Technology at ImmobilienScout24 he brought server operations back in-house, built a private cloud and switched the virtualisation platform while in live operation.
- Over 30 years in IT: Since 1990, including 18 years at Fiducia IT, then ImmobilienScout24 and idealo.
„What has been created is exemplary and shows the way for designing the systems of the future.“
Manfred Broy, jury CIO of the Year 2014

The situation
71 % have repatriated: why repatriation is a correction, not a reversal.
Cloud repatriation is treated as a trend in 2026 and frequently read as a reversal. The figures behind that are documented, not asserted.
71 %
of companies have already repatriated workloads from the public cloud according to IDC, alongside 21.5 % growth in the public cloud market. Workloads are being brought back and new ones are being moved to the cloud.

86 %
of CIOs cite repatriation plans for workloads from the public cloud, according to a Barclays survey.
Quelle: Barclays
57 %
of IT leaders would like to run their infrastructure within a single country, according to the Nutanix Enterprise Cloud Index 2026.

What's inside
Where do repatriation projects actually fail?
The whitepaper covers three propositions: that repatriation is evidenced, but as a correction, not a reversal, that self-service and elasticity are not properties of the hyperscaler, and that control comes from the operating model, not the location. Each proposition comes with three questions to place your own position within minutes.
01
Repatriation is evidenced, as a correction, not a reversal
The figures are clear. IDC puts the share of companies that have already brought workloads back at 71 %; a Barclays survey cites 86 % of CIOs with repatriation plans. The Nutanix Enterprise Cloud Index 2026 shows that 57 % of IT leaders would like to run infrastructure within a single country.
02
Self-service and elasticity are not properties of the hyperscaler
What users value about the cloud is rarely the data centre address. It is self-service provisioning, elastic scaling, API access and automation. These properties come from the platform layer, not from who owns the data centre. They can be built equally well in your own or a European facility.
03
Control comes from the operating model, not the location
A server in your own data centre is not yet control. Control means traceable access, documented configuration, reproducible recovery and the ability to change suppliers. All of these are operational properties. They can be better satisfied in a leased European facility than in your own basement.

What onehundred takes on
Consulting, transition, operation.
onehundred builds and operates the platform, in the customer's own data centre or in a German or European facility. The customer retains control over data, location and access, and still gets cloud-grade usability.
Consulting
Location analysis, on-premise versus hybrid architecture decision, workload-specific assessment
Transition
Building the platform in your own or a European facility, including the automation layer
Operation
Managed operations with cloud convenience: self-service, elasticity, defined recovery times
Where the assessment shows that a workload belongs in the public cloud, we say so. This offering is not a recommendation against the cloud but the ability to build both directions cleanly.
Questions
Frequently asked questions.
Isn't 'your own cloud in your own data centre' a step back to the classic data centre?
Do we need our own data centre?
Does data control mean giving up modern AI applications?
Who operates the platform day to day?
Conclusion
Where do you stand?
Repatriation makes sense where cost, compliance or control support it, and only there. Organisations that carry it out should take the platform layer with them, or they trade a cost problem for an acceptance problem. The nine questions in the whitepaper are cut so that afterwards you know whether workload assessment, automation or the operating model is your open item.
- Workload assessment
- Automation
- The operating model
Why now
Organisations that take the platform layer with them when they repatriate avoid trading a cost problem for an acceptance problem.
