Microsoft launches Fedora-based Azure Linux 4.0 for Azure cloud workloads
Microsoft released Azure Linux 4.0, a Fedora 43–based, open-source Linux distro tuned for cloud workloads on Azure; it is a minimal, text‑based OS with no GUI, uses the dnf5 package manager, and is available publicly in preview to run on Azure VMs and AKS, with Azure Container Linux as an immutable companion. The move signals Microsoft’s role as a Linux maintainer and aims to offer an end‑to‑end, single‑vendor OS stack with SBOMs, while non‑Azure installations aren’t supported and desktop use isn’t intended; WSL integration is planned for development workflows.
