Architecture Over Dependency: This Is What Our Infrastructure Looks Like Today

Digital sovereignty is not a feature – it is an architectural principle. After transitioning our toolchain to open source, the next step was to strategically rethink the infrastructure behind the tools.

In this post, we showcase how our modern IT architecture looks – container-based, automated, scalable, and fully under our control.

Why Infrastructure Is the Key to Freedom

Many companies replace individual tools but remain structurally dependent:

• on hyperscaling cloud providers,
• on opaque black-box services,
• on rigid hosting models.

Our goal was clear: To create a foundation that offers us maximum control, flexibility, and future-proofing.

Our Architecture at a Glance

We rely on a modular infrastructure that aligns with DevOps principles – built on open standards and fully documentable.

The Core Components:

How We Work: Automated and Traceable

GitOps Instead of Click Configuration

All changes to the infrastructure are versioned – no manual clicking around, no opacity. This brings:

• Reproducibility (from testing to production),
• Rollback Capability in case of errors,
• Auditability.

Continuous Delivery – But Controlled

Not everything has to go live automatically immediately. We rely on staged pipelines with manual gates for security-critical deployments.

Benefits We Are Already Experiencing

• Cost Savings by eliminating external PaaS models
• Better Performance, as we operate infrastructure closer to the use case
• Faster Innovation, because we manage dependencies ourselves
• Security by Design – from root policy to container

And above all: We have regained oversight – and control.

Challenges and Solutions

Of course, not everything went smoothly. A few learnings from the transformation:

Next Step: Efficiently Automating Operations

In part 4 of our blog series, we will show:

• How we efficiently manage operations and maintenance with Infrastructure as Code
• Which automations truly save time
• And why Self-Service IT is not a pipe dream, but a lived reality

Exchange Encouraged

Our infrastructure is no secret – it is an invitation to dialogue. For those on similar paths or looking to start: Let’s talk.

What architectural decisions have you made?

What works for you – and what doesn’t?

We look forward to the exchange.
