summary
Microsoft reports 60% of cores run Linux on Azure and maintains ~20,000 marketplace images with roughly 1,000 new image variants per month. Engineering delivers Azure-tuned kernels, per-kernel signoffs, and an Azure Guest Patching service that uses canonical app repository snapshots; a self-service validation API (preview) runs the open-source Lisa test framework (400+ test cases) and backs 4–5 million test executions monthly to catch regressions across thousands of VM SKUs.
