Microsoft Azure 宣佈支援 FreeBSD：「Microsoft has created its own FreeBSD image. Repeat. Microsoft has created its own FreeBSD image」，Microsoft 的正式公告在這：「FreeBSD now available in Azure Marketplace」。
Microsoft 所作的 patch 都有進 10.3-RELEASE 裡，主要是對於 Hyper-V 虛擬化後的效能補強：
The majority of the investments we make at the kernel level to enable network and storage performance were up-streamed into the FreeBSD 10.3 release, so anyone who downloads a FreeBSD 10.3 image from the FreeBSD Foundation will get those investments from Microsoft built in to the OS.
像是 10Gbps 網路這部份就有明顯的改善：
For example, our measured networking throughput on a 10Gb network on FreeBSD 10.1 was 2Gbps. With 10.3, we’ve been able to achieve over 9Gbps in testing
