The Germany Stack and the Reality of Modern Cloud-Native Development:

Digitization is no longer a buzzword – it is a foundation, a competitive advantage, and a geopolitical factor all at once. Europe has understood this. And with the Germany Stack, a reference architecture initiated by the Federal Ministry for Digital and State Modernization, an open, validated, and interoperable technology stack for software development in administration and business is being created for the first time.

The goal: A unified, secure, and sovereign IT foundation for modern applications – free from proprietary dependencies, based on open standards, and fully cloud-compatible.

This is a milestone. And it is long overdue.

However, anyone who works daily with Cloud-Native environments, multi-cluster deployments, and Infrastructure-as-Code knows: An architecture is not an end in itself. It thrives on the tools that make it usable.

And this is where ayedo comes into play.

A Brief Look at the Germany Stack

The Germany Stack is more than a diagram – it is a catalog of technical standards and technologies designed to enable the development of modern, interoperable software solutions.

In the official stack representation, familiar components can be found:

• Integration & Interfaces: gRPC, REST, OpenAPI, SOAP
• AI & Data: TensorFlow, PyTorch, RDF, DCAT, CSV, MLflow
• Persistence & Databases: PostgreSQL, MariaDB, MongoDB, MySQL, ScyllaDB
• LowCode & Automation: n8n, Budibase, Appsmith, Joget
• Security & Transport: TLS, IPsec, AES, SHA, JWT
• Communication & Networks: HTTP, SIP, DNS, BGP, IPv6
• Standards & Browser Technologies: HTML, CSS, React

A well-thought-out foundation focused on openness, verifiability, and stability – and thus an important step towards digital sovereignty. What this stack shows is remarkable:

Germany’s public IT architecture is finally moving away from proprietary single solutions towards modular, standardized components.

That alone is already a breakthrough. However, between reference and reality lies the production environment.

From Architectural Plan to Reality: What ayedo Already Delivers Today

ayedo has been operating productive Cloud-Native infrastructures for companies, authorities, and research institutions in Europe for years.

It’s not just about “hosting,” but about fully managed, sovereign platforms that integrate both cloud and on-premises environments.

Many of the technologies that the Germany Stack outlines as a future vision are already part of ayedo’s everyday practice:

Core Managed Databases

• PostgreSQL – the backbone of data-driven applications
• MariaDB – stable, open source, relational, and proven
• MongoDB – document-oriented agility for modern apps
• Qdrant – vector-based search engine for AI applications
• ScyllaDB – high-performance, scalable NoSQL database

Application & Workflow Layer

• n8n – Enterprise-level automation
• GitLab – DevOps platform for source code, CI/CD, and governance
• Kubernetes – the undisputed orchestration platform, fully managed on all European clouds
• OpenTelemetry, Prometheus, Grafana – complete monitoring and observability ecosystem

Thus, ayedo already covers a large portion of the “official” stack components – and does so multi-cloud-capable, standards-compliant, and GDPR-consistent. But the real strength lies in what goes beyond the stack.

The Difference Between Complete and Fully Usable

A tech stack, no matter how solid it may be on paper, only unfolds its impact through the right tools in daily operations.

In reality, the Germany Stack still lacks some essential components without which Cloud-Native software development can neither be efficient nor secure.

ayedo fills these gaps – with a fully integrated, European managed service ecosystem.

Here are the key extensions that ayedo offers beyond the official stack:

Cluster Management & Orchestration

• ArgoCD – GitOps for Kubernetes, declarative, secure, and reproducible
• Velero – Backup and disaster recovery solution for container clusters
• Kyverno – Policy engine for Kubernetes compliance
• cert-manager – Automated certificate management

➡️ Result: Complete automation and policy-driven governance of infrastructure and applications.

Identity, Access & Security

• Keycloak & Authentik – Open Source IAM with SSO, OAuth2, OIDC, LDAP
• Infisical & Vault – Secret management for sensitive configurations
• Netbird – Zero-trust network fabric for secure site networking

➡️ Result: Unified, European IAM system without cloud lock-in.

Observability, Logging & Metrics

• Grafana, Grafana Loki, VictoriaMetrics, VictoriaLogs
• Prometheus & Alertmanager
• OpenSearch – Search and analytics engine, Elasticsearch-compatible

➡️ Result: Complete transparency over infrastructure, services, and data flows – on European soil.

Data & Storage

• Ceph & Longhorn – Distributed storage at block and object level
• MinIO – S3-compatible object storage for any cloud
• ClickHouse – High-performance analytics engine
• Apache Kafka – Real-time event streaming
• InfluxDB – Time-series database for IoT and monitoring
• Harbor – Container registry with security scanning and signatures

➡️ Result: Full control over data and storage layers – without proprietary silos.

Digital Sovereignty Needs More Than Open Source

Many confuse open source with sovereignty. Both belong together – but one does not automatically guarantee the other.

Digital sovereignty does not mean “hosting everything yourself.” It means: retaining control over technology, data, and operational models.

ayedo enables exactly that: Companies, administrations, and research institutions can operate, manage, and audit every component – from the Kubernetes cluster to the IAM policy – in European data centers.

Open source here is not just a licensing model, but a principle of trust. Everything ayedo operates is transparent, documented, and verifiable. This is lived digital autonomy – not just proclaimed.

A Stack Is Only as Good as Its Operability

The reality in many organizations looks like this: Even if the technology stack is defined, there is a lack of know-how, resources, and operational processes to operate it securely and efficiently.

This is understandable – the operation of distributed systems, service meshes, and security layers is highly complex.

What ayedo provides here is a Managed Cloud Native Stack as a Service – a fully operable, modular stack that works on any European cloud (e.g., IONOS, OVH, Scaleway, Exoscale, plus sovereign on-prem infrastructures).

Companies receive:

• Enterprise-grade Kubernetes clusters
• Integrated observability stack (Prometheus, Grafana, Loki)
• Security & IAM layer
• Automated backups, DR, and replication
• Databases as managed services
• Event streaming and message queuing
• Zero-trust networks
• Policy & compliance engine

All operated, maintained, and supported – 100% in European regions.

Why This Is More Than “Just Hosting”

Hosting is infrastructure. Operation is responsibility. Sovereignty is an attitude.

What ayedo does is not classic hosting. It is architectural consulting, automation, and sovereignty enablement in one. The goal: Empowering customers to operate their own systems – independently, securely, transparently.

Unlike global hyperscalers, where lock-ins and data transfers are hardly avoidable, ayedo offers:

• full data ownership
• no proprietary APIs
• open standards
• multi-cloud compatibility
• auditable operational processes

And all with a focus on European values and legal frameworks.

The Germany Stack as a Foundation – ayedo as an Accelerator

The Germany Stack is an excellent step in the right direction. It defines what modern, secure, and interoperable IT should be – open, modular, transparent. But architecture alone is not enough. It requires operational experience, integrated tools, and European providers who implement these principles in production environments.

ayedo is positioned precisely there. With managed services that:

• operationalize the stack,
• complement missing components,
• and make everything run on European clouds.

Conclusion: Europe Can Do Cloud-Native – If We Want It

Digital sovereignty is achievable. But it requires consistency: in technology selection, architecture, and operation.

The Germany Stack shows the way. ayedo is already on it – with partners, customers, and communities across Europe.

The future of European cloud infrastructure is not born out of competition with hyperscalers, but in collaboration, openness, and operational excellence. And those who are ready today to rely on open standards, auditable systems, and resilient architectures will gain a real strategic advantage tomorrow.

ayedo is actively working with organizations, ministries, and companies to bring the Germany Stack from architectural model to productive operation – sovereign, secure, and cloud-native.

Digital sovereignty does not begin with regulations. It begins with the decision to truly understand and master technology.
