Egress Traffic Management in Kubernetes

Egress Traffic Management in Kubernetes

For years, Kubernetes has provided proven mechanisms to manage incoming traffic into a cluster. Ingress controllers serve as a defined "bottleneck" through which external requests enter and are handled with clear rules – such as for routing, TLS, or authentication. However, the situation for outgoing traffic, known as **egress traffic**, is less clear. By default, egress traffic leaves the cluster via the node where the pod initiating the connection is running. There is no central control instance comparable to the ingress controller.

From OTRS to Zammad – 50,000 Tickets Find a New Home

From OTRS to Zammad – 50,000 Tickets Find a New Home

The transition from OTRS to Zammad is more than just a technical upgrade for many organizations – it's a step towards a sovereign, modern, and highly available ticketing infrastructure. In this blog post, we describe in detail how we successfully migrated **50,000 tickets** from a non-highly available OTRS 6 instance to a **self-hosted Zammad instance** running on Kubernetes.

Digital Powerlessness – Germany Ensnared by Big Tech - A Film by ARD

Digital Powerlessness – Germany Ensnared by Big Tech - A Film by ARD

The fact that the Bundeswehr will store its data in the Google Cloud is not an IT project. It is a security policy capitulation. Just like the decision to give Peter Thiel's Palantir direct access to German police data. These two examples are not isolated missteps – they are expressions of systemic failure. Germany has relinquished its digital sovereignty.

Microsoft Eliminates Traditional Volume Licenses

Microsoft Eliminates Traditional Volume Licenses

Starting November 1, 2025, Microsoft will eliminate traditional volume licenses. Specifically affected are the major licensing models **Enterprise Agreement (EA)** and **Microsoft Products and Services Agreement (MPSA)**. Previously, companies could receive discounts between 6 and 12 percent off the list price depending on the volume purchased. This will soon end. From November, all customers will fall into price level A – and will pay the **full list price** as it appears on the Microsoft website.

k3k: agent-less k3s in Kubernetes

k3k: agent-less k3s in Kubernetes

* **Controlplane on demand:** With k3k, you can run a **fully-fledged k3s control plane as a Kubernetes workload** – without agent nodes. This enables lightning-fast **spin-up/down** of complete, valid k3s clusters for testing, tenants, or edge scenarios. (Background: *agent-less servers* are a feature of k3s where the control plane is not a normal node in the cluster, as is usually the case)

Zero Trust Network Access (ZTNA) with NetBird – The Open-Source Alternative

Zero Trust Network Access (ZTNA) with NetBird – The Open-Source Alternative

In a world where cloud-native architectures, remote development, and complex multi-cluster infrastructures have become the norm, traditional VPN-based access is simply outdated. Zero Trust Network Access (ZTNA) is not just a trend but a necessity: a modern paradigm where **trust is never blind and every access is explicitly verified**—regardless of location, device, or network.

Artifact Management – Why Blind Trust in Public Artifacts is Dangerous

Artifact Management – Why Blind Trust in Public Artifacts is Dangerous

Cloud-native software development is built on a foundation that usually remains invisible: **artifacts**. These include Docker images, Helm charts, operator packages, and other components essential in modern Kubernetes workflows. Almost every project—from small APIs to complex AI platforms—relies on these packages. But how stable is this foundation really when sourced from the **community or third parties** without safeguards, mirroring, or governance?

Kira: Why We Are the First to Use an AI Influencer – and What It Means for ayedo

Kira: Why We Are the First to Use an AI Influencer – and What It Means for ayedo

An AI influencer is not a human who spontaneously decides whether to post a video or a post today. An AI influencer is a digital persona, fully constructed, always available, never in need of a vacation, and capable of producing high-quality content in seconds. That's exactly what Kira is. She will speak for us – about Cloud-Native technologies, AI and hosting news, in videos, podcasts, and on LinkedIn.

Why Helm is the Standard for Kubernetes Apps

Why Helm is the Standard for Kubernetes Apps

In recent years, Kubernetes has evolved from an experimental playground to the de facto standard for cloud-native applications. Its flexibility and scalability are impressive, but they come at a cost: significantly increased complexity in managing deployments, configurations, and releases. Anyone seriously operating or delivering software on Kubernetes will sooner or later face the question: How do I package my application so that it is reproducible, maintainable, and easily integrable?

Transatlantic Illusion – How Europe Becomes a Supplier of Data and Investment

Transatlantic Illusion – How Europe Becomes a Supplier of Data and Investment

The celebration over the recent "deal" between the EU and Donald Trump seems like a macabre staging. While Brussels publicly celebrates "planning security in uncertain times," the real power dynamics continue to shift westward – economically, technologically, politically. They speak of partnership, but what they mean is submission.

Palantir and the Police: How Surveillance Software Becomes a Threat to Civil Rights

Palantir and the Police: How Surveillance Software Becomes a Threat to Civil Rights

**Palantir in Germany** is more than just a software provider. It symbolizes a quiet shift in the state: away from democratic control, towards data-driven surveillance by external tech corporations. And right in the middle of it all—German interior ministries spending millions on a system they neither understand nor control.

Cloud First is Yesterday – Why Europe Must Finally Digitally Sovereignize

Cloud First is Yesterday – Why Europe Must Finally Digitally Sovereignize

For a long time, digital transformation was considered a technical project: faster, more scalable, more efficient. Those who ventured into the cloud early were seen as bold, modern, progressive. Today, over a decade later, we must acknowledge: The cloud is no longer just a technology topic – it is also a political question.

One Year of OZG 2.0: The Digital Administration Still Awaits Its Breakthrough

One Year of OZG 2.0: The Digital Administration Still Awaits Its Breakthrough

One year after the enactment of the Online Access Act 2.0, the results are sobering. The big promises remain, but noticeable progress for citizens and administrations is scarce. A central solution has long been on the table: **Cloud-native technologies**. The **BSI itself recommends containerization, Kubernetes, and modular architectures**—not as a fad, but as a solid foundation for a secure, scalable, and modern administrative infrastructure.

The Digital Sellout of Europe – And We're Paying for It!

The Digital Sellout of Europe – And We're Paying for It!

**70% of European companies consider their dependency on non-European technology too high.** This is not a gut feeling, but the result of the current "State of Cybersecurity Report 2025" by HarfangLab. A wake-up call. Yet, the majority of our data traffic continues to flow to where our laws end: American data centers, operated by platforms that have more in common with stock prices and geopolitical interests than with European IT reality.
