Microsoft's Linux server distribution is now available as an ISO to install on your own server or virtual machine.

Why this matters
Why now

Microsoft is strategically expanding its server operating system offerings, moving beyond Windows Server to cater to diverse enterprise IT infrastructures, especially given the growing adoption of Linux in cloud and data center environments.
