#347: Andrei Kvapil has been around Kubernetes since the early days. Contributor to Cilium, Kubevirt, and a handful of other projects you probably use without realizing it. He is also the maintainer of Cozystack, a CNCF sandbox project, and the CEO of Aenix, the company behind it.
In our previous article, we showed you how to build a platform that deploys multiple managed applications through a unified API and UI…
I have spent many years dreaming about building my own cloud platform. After several attempts within different companies, I finally launched my own project, Cozystack. In this article, I am going to share our experience and our approach to building a modern infrastructure platform around Kubernetes and its API. I’ll dive into the “platform approach” — what platform is, how it works, who it’s for, and how to get one off the ground. Plus, I’ll compare different architectures, explain why we went with K8s, and show you how we put together a production-grade solution based on it.
When it comes to running virtual machines in Kubernetes via KubeVirt, the first question engineers ask is: “What is the overhead?” Let’s dive into the details and break it down by three key areas: compute, storage, and network.
To get why there’s almost no CPU overhead, we need to look at how the Linux kernel handles containers.
Hi! I’m Andrei Kvapil CEO of Ænix and developer of Cozystack, an open source platform and framework for building cloud infrastructure. In this article I’ll walk through the way we deliver applications to Kubernetes, explain why regular GitOps can be awkward in local development, an show how the new tool cozypkg fixes those pain points. The article targets engineers who already know Helm and Flux.
First, I’ll introduce Cozystack, as it’s important for the context. Cozystack is a cloud platform that lets you run and offer managed services — databases, VMs, Kubernetes clusters, and more. Cozystack takes care of the full life‑cycle of every service.
Hello everyone! I’m Andrey Kvapil, CEO of Ænix and developer of Cozystack, an open-source platform and framework for building cloud infrastructure. In this article, I want to share my perspective on how modern cloud patterns have transformed infrastructure approaches, the evolving role of service providers and public clouds in this landscape, and most importantly, how virtualization’s purpose has fundamentally changed in today’s infrastructure stack.
Modern applications rely on an ever-growing stack of technologies: databases, caches, queues, S3 storage, and more. This complexity increases technical and cognitive operational burden on infrastructure teams. As a result, skilled engineers command premium salaries, making infrastructure maintenance far more expensive than application development itself.
Talos Linux is a specialized operating system designed for running Kubernetes. In my opinion, it does that task better than others. First and foremost it handles full lifecycle management for Kubernetes control-plane components.
On the other hand, Talos Linux focuses on security, minimizing the user’s ability to influence the system. A distinctive feature of this OS is the near-complete absence of executables, including the absence of a shell and the inability to log in via SSH. All configuration of Talos Linux is done through a Kubernetes-like API.
