2018

Changes Details
New resource provider for a SQL Server cluster A new resource provider (Microsoft.SqlVirtualMachine/SqlVirtualMachineGroups) defines the metadata of the Windows failover cluster. Joining a SQL Server VM to SqlVirtualMachineGroups bootstraps the Windows Server Failover Cluster (WSFC) service and joins the VM to the cluster.
