+A talk by Thilo - flatcar maintainer and cool guy.
+The talk consisted of multipe demos and a warning of this being the alpha version of the talk but most things worked out fine.
+
+## Baseline
+
+- **Why selfhost:** Why not? Cost efficiency, vendor independence, sovereignty requirements, customization, ....)
+- **Why our stack is kubernetes:** FOSS, community driven, versatile, stable, broad ecosystem, ...
+- **You can run it on any host**: Baremetal, Private Clouds (OpenStack, Proxmox),m Public Clouds (AWS, GCP, Azure, Stackit, Akamai)
+- **Choose your favorite OS**: Flatcar, Ubuntu, ...
+
+## The demo
+
+- **Problem:** Sovereignty is hard to proove
+- **This talks demo:** Cloud agnostic provisioning of kubernetes clusters on localhost (QEMU), Hetzner and Akamai
+- **How**: Just use one shared flatcar snapshot to provision on all cloud/localy
+- **QEMU Specual**: Qemu is not really a vm orchestrator, so wee need a little hack to enable cross-vm networking (not needed on other hypervisors/clouds)
+- **In-place updates**: Through kured (kubernetes update and reboot daemon)
+
+## Why Flatcar is cool
+
+- One config for many environments
+- Seamless migration to other cloud-providers and cross-clopud c,usters
+- Community driven and CNCF-backed
+- Managed updates
+- Airgapping
+- Extendability through sysext
+
+## What is **real** sovereignty
+
+- You can operate it youirself?
+- You can keep it stable?
+- Is your stack well stewarded/maintained and can you join?
+- Can you own it (fork, etc)?
