A failover cluster created in Windows Server 2016 can use a new quorum introduced in Windows Server 2016. "Cloud Witness" is a new type of Failover Cluster quorum that can leverage Microsoft Azure Public Cloud as the arbitration point. When you configure quorum settings using "Configure a Cluster Quorum Wizard", in Windows Server 2016 Failover Cluster, you will see an option to configure Microsoft Azure as the quorum for cluster.
Benefits of using Microsoft Azure as Quorum:
- Eliminates the need for a third datacenter or physical hardware.
- Zero maintenance of the quorum device.
- Use the publically available Blog storage for storing the quorum settings
