01 Managed cloud and hybrid IT from Berlin

Modern infrastructure is not a place. It is an operating model.

We advise on, migrate and operate platforms on an open stack: private cloud, cloud exit, VMware replacement, NIS2 resilience and AI infrastructure. In German data centres or in your own. Consulting, transition and operation from a single source.

Book a call Or browse the solutions first

Experience: More than 100 migrations in three years, ten of them documented
Operations: 24/7 with on-call duty, patch and escalation management
Location: ISO 27001 certified data centres in Germany, or your own
Exit: Open, documented stack: any competent provider can take it over

These companies trust us with their operations, from 20-person teams to enterprises

02 Six routes, one principle

Which decision is on your desk?

Every solution starts with an assessment, moves through a step-by-step migration with a go/no-go at each transition and ends in round-the-clock operations. The difference is the starting point.

NIS2 and digital sovereignty

Sovereign cloud from a European cloud provider that also runs it

A server in Frankfurt is not sovereignty yet. What decides the question is who can gain access under which law, who operates the platform and whether you could change your architecture without anyone else agreeing. We establish where you actually stand, rebuild your sovereign cloud on open standards step by step and then run it around the clock.

NIS2 and digital sovereignty

Disaster recovery services that start at the backup and end in operations

The NIS2 directive requires an operation that can be demonstrably restored. Germany transposed that on 6 December 2025 with no transition period, and every other member state has its own national act. Our disaster recovery services cover the technical side of it: backup architecture, immutable copies, rehearsed recovery procedures and the operations around them. The legal assessment is not part of it.

Cloud exit and cost analysis

Cloud migration services in both directions: numbers first, move second

Whether a workload belongs in the public cloud or back in your own data centre is not a matter of conviction but a calculation, and we put it on the table. We then migrate in whichever direction the numbers point and operate the result. The entry point is a cloud exit and TCO assessment, not a move.

AI infrastructure

A dedicated GPU server is the easy part. You need AI infrastructure that survives operations.

We build and run AI infrastructure for inference and model hosting in an environment you control: in your own data centre or in a European sovereign data centre. The entry point is a readiness assessment, not an order form. Consulting, build and operations come from one team.

View solution

VMware replacement and open operations

The VMware alternative that someone still runs afterwards

Since the Broadcom acquisition in November 2023 there are no perpetual VMware licences any more. Your VMware alternative is Proxmox VE or KVM, and we move the vSphere estate across service by service, with a fallback path and no cut-over date. Then we take over operations, around the clock and with on-call cover.

Private cloud in your own data centre

Private cloud services in your own data centre, operated around the clock

Self-service, elasticity and automation are properties of the platform, not of the hyperscaler. We build your private cloud in your own data centre, in colocation or in German data centres, migrate your systems onto it and run it 24/7. Data, location and access stay with you.

03 How we work

One contract, one team, one responsibility

No patchwork of consultancy, systems integrator and operator. The people who run the assessment are the people who run operations afterwards. That changes how honest the assessment is.

Consulting

Where you stand, how your stack rates, and a target picture with costs and risks. The first go/no-go decision happens here.

Transition

Build and stress a test environment, then migrate service by service with a rollback path. No cut-over day where everything tips.

Operation

24/7 operations with on-call duty, monitoring, patch and escalation management and ongoing advice.

Three of ten documented projects

Textbroker

Content platform · over 100 permanent staff plus tens of thousands of freelance authors

A self-built AWS environment with more than 50 services. Then the systems architect, the platform manager and the DevOps people left the company. Suddenly nobody was operating what was running there.

75 per cent lower platform and service costs at unchanged availability. Operations carried on even though the key people were gone.

DebianApache2TomcatPerconaMariaDBGitLabDocker

Innotech

Software development and wood technology

The application ran in Azure, with severe performance problems, a database design at its limit and a cost curve that only pointed upwards.

Two months from breaking ground to the new production environment on private cloud, followed by 24/7 with patch and escalation management.

ProxmoxDebianHAProxyPostgreSQLDockerRedis

Aerosoft

Simulation software · over 40 permanent staff, more than 50 freelance developers

Their own dedicated infrastructure, but the load peaks are brutal: product launches and Black Friday. An outage at the wrong moment costs a quarter of revenue.

Availability permanently above 99.9 per cent, the complete stack from network through virtualisation to database from one source.

05 Insights

Guides for decisions you only make once

The NIS2 directive: who is in scope and what has to be builtThe NIS2 directive does not apply directly. It reaches organisations through the act each member state passes, and Germany’s has been in force since 6 December 2025, without a transition period and for around 29,500 organisations. This page sets out who is covered, which duties follow and what they mean for backup, recovery and day-to-day operations. It does not replace legal advice.Read Digital sovereignty: location, access and operations held apartSovereignty is usually argued as a question of location: where do the servers stand? In practice it is decided by two further questions. Who can gain access under which law, and who operates the platform in a way that lets you change the architecture without anyone else agreeing. This article separates the three levels and shows which evidence the NIS2 directive and its national implementations now require.Read Cloud costs: where they come from and when an exit pays offCloud costs rarely rise where the load rises. They rise along data paths, in reserved capacity and in contract details that appear in no plan. This article sets out how total cost of ownership is calculated honestly, which levers work without moving anything, and at what point an exit becomes economic.Read Sovereign AI is decided in the infrastructure, not in the modelSovereign AI is not a property of the model. Whether an AI initiative runs securely, verifiably and economically depends on the layer beneath it: compute, storage, network, platform and operations. This article sets out what belongs to that layer, which obligations from the GDPR and the EU AI Act reach through into the architecture, and when self-hosted inference beats an API.Read Vendor lock-in: how to spot it and how to undo itA lock-in goes unnoticed for as long as the price is right. It becomes visible when the vendor changes the terms and nobody can say what a switch would cost. This piece sets out the forms of vendor lock-in, the warning signs, Broadcom and VMware as the object lesson, and the one criterion that can actually be tested: exit capability.Read Cloud compliance: how to tell a compliant cloud from a claimAlmost every provider page promises cloud compliance, and almost none of them means the same thing by it. This text sorts out what compliance is actually made of, why a European data centre on its own is too thin a criterion, and which options really sit between your own server room, a private cloud and the public cloud.Read
