Penguins crash the Windows party
Microsoft's Azure Linux
Azure Linux drops: Linux fans cheer, Windows loyalists squint, Azure skeptics breathe fire
TLDR: Microsoft publicly shared Azure Linux, its streamlined in-house system for running Azure cloud and edge servers. Comments split between cheers for Microsoft embracing open source and skeptics swearing off Azure, with memes aplenty; it signals Redmond’s deeper Linux shift without replacing Windows, and you can try it today.
Microsoft just rolled out Azure Linux, its own lightweight flavor of the open-source OS, and the comments immediately caught fire. One user gasped, “damn when did this come out?” while another declared, “Even Microsoft is betting on Linux now,” taking a swipe at Windows 11. Cue the chorus of clarifiers insisting this isn’t a Windows replacement, just the engine for Microsoft’s cloud and edge machines. The pitch: a tiny core, quick boots, fewer moving parts, and fast security patches—plus public ISOs to try at home and community support on GitHub.
Then the drama: one commenter joked, “I for one welcome our open source overlords,” while another shot back, “Not even at gunpoint would I choose Azure.” Fans say this is Microsoft finally contributing upstream and giving Linux real love; skeptics call it a PR play to keep you inside Azure. Reality check: Microsoft says it won’t replace other Linux options, and it’s mostly for its own servers, built with a simple tool that makes packages and images. Want in? Grab the ISO, verify it, spin a quick VM, and join the public community calls. The internet’s verdict: cautious applause, spicy side‑eye, and plenty of penguin memes. For now, anyway.
Key Points
- •Azure Linux is Microsoft’s internal Linux distribution for cloud infrastructure and edge services, publicly shared to support open source.
- •It uses a small common core with the ability for teams to layer additional packages, enabled by a simple build system.
- •The build system supports package generation (RPM from SPEC files) and image generation (ISOs, VHDs).
- •Azure Linux emphasizes lightweight resource use, faster boot, minimal attack surface, and supports both package-based and image-based updates via RPM.
- •Azure Linux 3.0 ISOs for x86_64 and aarch64 are available, with community-based support via GitHub issues and scheduled public community calls.
