Ubuntu
Ubuntu is a complete desktop Linux operating system, freely available with both community and professional support. The Ubuntu community is built on the ideas enshrined in the Ubuntu Manifesto: that software should be available free of charge, that software tools should be usable by people in their local language and despite any disabilities, and that people should have the freedom to customise and alter their software in whatever way they see fit.
Talos Linux
Talos is a specialist Linux-based operating system for running Kubernetes, an open-source system for automating deployment, scaling and management of containerised applications. Minimal, immutable and hardened, it does not offer any shell or interactive console; instead, all system management is done via remote Application Programming Interface (API) calls, where messages sent from a client application are protected with mutual Transport Layer Security TLS (mTLS) authentication.
