Host highly scalable workloads on a 100% European cloud stack without sacrificing performance or handing your encryption keys to a US tech giant.
Adfinis and IONOS have forged a partnership built on the shared DNA of open source, transparency, and the rejection of vendor lock-in. As the IONOS Consulting Partner of the Year 2025, Adfinis provides the engineering expertise to turn IONOS’s raw, high-performance Infrastructure as Code (IaC) into a fully managed, automated enterprise ecosystem.
The strength of this collaboration lies in combining the sovereign European cloud's "clean concrete" foundation with the "smart architecture" that Adfinis has honed over 25+ years of open source expertise.
We "un-stick" clients locked into proprietary hyperscaler services by refactoring them into cloud-agnostic, open source equivalents optimized for IONOS.
Adfinis deploys SLSA Level 3-compliant pipelines and OpenBao secrets management on IONOS, ensuring mathematically verifiable data integrity where you retain all encryption keys.
Free your IT team to focus on innovation while we manage your infrastructure. With flexible services tailored to your needs, we ensure smooth, secure 24/7 operations, giving you peace of mind.
IONOS is the premier choice for organizations that require high-performance IaaS and standard, unopinionated Kubernetes without the "walled garden" constraints of the Big Three. By operating strictly under European legal frameworks, IONOS remains immune to foreign data access requests, such as the US CLOUD Act, providing a secure, BSI C5- and ISO 27001-certified environment for regulatory compliance.
Beyond security, IONOS offers a breath of fresh air for procurement and operations teams alike. With transparent pricing that eliminates "egress shock" and a commitment to open integrations, it serves as a high-performance foundation that scales on demand without forcing customers into a proprietary ecosystem.
We live and breathe GitOps and CI/CD, using tools like Terraform to ensure your infrastructure is repeatable, scalable, and human-error-proof.
With a focus on open source solutions, Adfinis ensures transparency, vendor independence, and long-term scalability in the solutions we build with our customers.
With over two decades of experience in complex Linux and Cloud Native environments, we provide the deep technical "know-how" to solve the problems that standard support desks can't.

The future of IT lies in open source, in 'a touch of AI,' and above all in connecting people who bring their visions to life together. That is why we are incredibly proud to have more than just a partner in Adfinis. We have found friends and like-minded professionals with whom we can shape and realize ambitious visions. Adfinis is more than one of Europe’s leading open source partners; it is a community of outstanding specialists and inspiring people who have turned their passion into their profession.
