High Performance and High Availability for SQL Servers on Azure
SQL Server is typically deployed in a standalone configuration within an AlwaysOn Availability Zone, making it vulnerable to downtime if there is an outage in the Availability Zone.
Through a joint effort with Azure, SIOS clustering software enables native SQL Server Failover Clustering for Azure deployments without the need for shared storage. Create a SQL Server cluster using only local storage and add SIOS software for host-based, block level replication that keeps data synchronized between nodes and enables failover across Always on Availability Zones.

SQL Server Cluster in the Cloud: Protected by SIOS
SIOS SANLess clusters provide complete protection without the limitations of SQL Server AlwaysOn Availability Groups or traditional shared storage based SQL Server AlwaysOn Failover Cluster Instances (FCI).
SIOS SANLess clusters support multi-Availability Zone deployments, unlimited databases per SQL Server instance, and applications that rely on the Microsoft Distributed Transaction Coordinator.
