Understanding Kubernetes, not just using it: ayedo now offers hands-on IT workshops
Technological independence starts with your own expertise. ayedo offers hands-on workshops on Kubernetes, Docker, GitOps and Polycrate for IT teams.
Why Data Transfer Fees (Egress) During Container Updates Drive Up Cloud Costs
When calculating the operating costs of their IT infrastructure in the cloud, most people take a standard look at the obvious items: What do virtual machines (compute) cost, and how much does the provider charge for pure storage space per gigabyte? Budgets are released and migration plans are forged based on these two variables. But once the containerized infrastructure goes live and modern CI/CD pipelines roll out fresh software releases several times a day, the end of the month often brings an unpleasant surprise when looking at the cloud bill.
The Air-Gapped Paradigm: Security Architectures for Isolated On-Premise Environments
In discussions about cloud transformation, the narrative often suggests that the future of IT lies solely in globally connected, public cloud infrastructures. However, for operators of critical infrastructures (KRITIS), defense companies, research-intensive industries, or highly regulated sectors in finance and healthcare, the reality is entirely different. When systems control nuclear command centers, core medical areas, or sensitive state secrets, the risk of internet connectivity is simply unacceptable.
Long-term Artifact Persistence: Why a Dedicated Container Registry is Essential for AI Models
When IT decision-makers and data engineers discuss the deployment of machine learning and artificial intelligence, the focus is almost entirely on frameworks, algorithms, and GPU performance. However, one aspect is regularly underestimated in the early stages—with fatal consequences for stability in later production operations: **artifact management**.
Scaling Data Engineering Pipelines: Apache Airflow on Kubernetes Best Practices
In the world of data engineering, Apache Airflow is the undisputed champion for workflow orchestration. However, with success come scaling pains: local executors hit CPU limits, Celery worker clusters are cumbersome to maintain, and resources sit idle when no DAGs are running.
Artifact Management for Data Science: Versioning Models and ETL Jobs with Harbor
In software development, versioning code is standard. However, in data engineering and AI projects, this is not sufficient. A model consists not only of code but also of a specific combination of training data snapshots, library dependencies (Python packages), and the weighted parameters of the model itself.

Software Supply Chain Security: The Immune System of Your CI/CD Pipeline
In the past, securing the front door (the firewall) was enough. But today, threats come "delivered to your door"—hidden in the thousands of dependencies we load into our systems daily via `npm`, `pip`, or `docker pull`. A single compromised component in an open-source library can cripple your entire infrastructure from within.
Runtime Bugs: Threat to Docker Hosts
Containers are the backbone of modern cloud infrastructure. They offer developers and ops teams unmatched agility and efficiency, based on the promise of robust isolation. However, this foundation is regularly tested. The discovery of critical **runtime bugs** that allow attackers to escape a container and gain root access on the host system is a serious warning.
Docker Swarm is Not Kubernetes for Beginners
When discussing container orchestration today, two terms quickly come up: Docker Swarm and Kubernetes. Both promise to run containers across multiple machines, scale services, and automate deployments. And because Kubernetes has a reputation for being complex, many organizations initially turn to Docker Swarm, hoping to ease into the world of container orchestration with less effort.
Docker Here, Docker There – I'm Going Back to the Old Ways
You hear it more and more often, half-serious, half-annoyed: "Docker here, Docker there – I'm going back to the old ways."
Docker Swarm or Kubernetes - Which Causes Less Pain?
In many discussions with IT leaders, sysadmins, and architecture decision-makers, a recurring pattern emerges: The question of "Swarm or Kubernetes" is not only a technological one but also strategic. Which platform offers less operational pain, more scaling potential, and long-term stability? After years of operational experience, ayedo has a clear preference – [Kubernetes](/kubernetes/). However, this doesn't mean Swarm lacks validity. On the contrary, one shouldn't believe that choosing Swarm today as a long-term solution will bypass the Kubernetes learning curve. Eventually, you'll find yourself with Kubernetes, facing the typical "and suddenly" problems that Swarm brings, especially in larger environments.
Docker vs. VM – What Is Actually the Difference?
Many people nod knowingly when the conversation turns to "containerization" or "virtual machines" – but honestly: those who can truly explain **where exactly the difference lies** are rarer than you think.
Vibecoding Kills Software. AI Amplifies What You Can – or Can't Do.
Everyone is writing software with AI now. Prompt in, code out. A few lines of Typescript here, a Dockerfile there, and somehow everything flies. People feel productive. Because they have output.
Containers Natively on Mac: Apple Gets Serious
With the announcement of macOS 26 ("Tahoe"), Apple quietly but fundamentally reshuffles the cards in the DevOps landscape. For the first time, the operating system offers native support for Linux containers—without Docker, without Orbstack, without additional dependencies. A move that not only reduces technical friction but also has the potential to reposition the Mac: as a fully-fledged, system-level development environment for cloud-native workflows.
Docker vs Kubernetes
In this article, we delve into what Kubernetes and Docker achieve, where their differences lie, and why you should combine both technologies to unlock their full potential.
How to Handle 160 Million Users a Month? With K8s and Docker!
Prime Insights is one of the world's leading companies in market analysis and data collection. More than 160 million users utilize Prime Insights' services every month. By migrating to the ayedo Cloud, more than 70% of infrastructure costs were saved compared to AWS. At the same time, the new hosting infrastructure enabled seamless handling of the customer's exponentially growing user numbers, so today more than 10 times as many requests are processed as 12 months ago - and the systems are still underutilized.
