Cloud & serverless

Cloud by requirement, not by vendor logic

AWS, Azure or Hetzner: we choose by requirement, budget and data protection instead of pushing every project into the same cloud.

Serverless is strong when load fluctuates. A properly sized server is strong when it does not. We tell you what your case needs – even when the answer is unspectacular.

Cloud and serverless architectureInfrastructure on AWS, Azure and Hetzner
What the decision rests on

When AWS, when Azure, when Hetzner

Choosing infrastructure is a cost decision with a long half-life. We make it based on your load profile, the know-how you already have, and the rules that apply to your data.

AWS when you need building blocks: a wide range of managed services, mature serverless, and control down to the details. The price is complexity – and a bill you have to watch actively.

Azure when Microsoft is already there: where Entra ID, .NET and Microsoft 365 shape daily work, Azure saves integration effort and internal negotiation.

Hetzner when predictability matters: under steady load, servers in German data centres often cost a fraction – at prices you know in advance. Smaller projects start on cloud instances, larger ones on dedicated machines. For many applications that is the more honest answer.

And frequently mixed: application and database predictable at Hetzner, with object storage, CDN or individual services from a hyperscaler – usually Google Cloud where BigQuery and its AI services decide it. We keep the dependencies small enough that moving later stays possible.

From architecture through to the invoice

Our cloud services

We build and we operate: architecture, automation, monitoring and cost control – so infrastructure stops being a standing item in your meetings.

Architecture & provider choice

A reasoned recommendation with a cost estimate for your load profile – including the option we do not recommend, and why.

Serverless & containers

Lambda, Functions and container services where load fluctuates or events are processed – with cold starts and limits accounted for.

Infrastructure as code

Reproducible environments from Terraform instead of a hand-clicked console: staging and production differ in parameters, not by accident.

GDPR & data location

Hosting in Germany or the EU, processing agreements, encryption, and backups that have actually been tested.

Monitoring & operations

Metrics, logs and alerts that say something when it matters – plus runbooks, so more than one person knows what to do.

Cost control

We find the line items that grow quietly: idle capacity, expensive egress, oversized databases. Usually this pays for itself immediately.
Our platforms

Where we operate

AWS and Azure for managed services and serverless, Google Cloud where it fits, and cloud instances and dedicated servers at Hetzner for predictable load in German data centres. Alongside them, the technologies built for managed cloud operation.

How we settle the infrastructure

Four questions answered before any provider decision:

What does the load actually look like?

Steady, with daily peaks, or in rare waves? Serverless pays off under fluctuation and gets expensive under constant load. Without that number, any recommendation is a guess.

What rules apply to the data?

Health, financial or HR data narrows the choice of regions and providers considerably. That belongs at the start, not in the acceptance phase.

What can your team operate?

The best architecture is the one your team can handle day to day. We deliberately build simpler when we will hand operations over later.

How expensive is leaving?

The deeper the provider-specific services sit, the pricier a move becomes. We wrap them so that migrating stays a decision rather than a rewrite.

Not sure whether your cloud bill matches the value you get – or planning a new environment?
