It’s happened at last: Microsoft has its own version of Linux. But don’t expect to download an .ISO just yet. It isn’t publicly available — it’s an internal project developed to help run Microsoft networks such as Azure.
Microsoft’s Azure Cloud Switch (ACS) is not a Linux distribution on the order of Red Hat’s or Ubuntu’s; rather it’s closer to Cumulus Linux. ACS was built specifically for Microsoft’s own needs, and therefore is not a definitive sign that Microsoft is becoming a Linux player.
All in the Microsoft family
As described in a blog post yesterday, ACS is “a cross-platform modular operating system for data center networking built on Linux.” It is intended to run on commodity ASIC hardware from multiple switch vendors and to run Microsoft’s own software for managing network devices.
