Free 50-Min Engineering Jam Session with Andrei Kvapil
No pitches. No fluff. Just real technical insights and problem-solving
What’s on the table:
🗜 Tear apart your infra (cloud, k8s, or bare metal – GPUs included)
🗜 Problem-solve databases, virtualization, or scaling nightmares
🗜 See how Cozystack + CNCF OSS actually works under the hood (and when it’s not the right fit)
About Andrei:
Built Cozystack (CNCF Sandbox). Been breaking clouds since k8s was still wearing diapers. Contributed to Cilium/KubeVirt/Linstor when they weren’t cool yet.
👉 Hit him up at aeinx.io/contact – subject line “engineering jam” + your toughest problem.
❤️ Please like and share this post with friends who are tired of struggling with infrastructure puzzles

In this article Andrei Kvapil explores how virtualization has evolved from DIY hypervisors to turnkey managed platforms and why this shift is critical for modern infrastructure.
Key takeaways:
🔹 The rise of "as-a-service" models – Why enterprises are ditching complex self-managed setups
🔹 Local providers’ advantage – How regional players outperform hyperscalers in digital sovereignty and compliance
🔹 The new stack – Kubernetes, lightweight VMs, and automation redefining virtualization
