About SQL Server high availability (HA) environments
SQL Server Intelligent policies support the following types of SQL Server HA environments: SQL Server clusters and log-shipping. For log-shipping, the same caveats as for legacy SQL Server policies.
SQL Server legacy policies support the following types of SQL Server HA environments: AlwaysOn Availability Groups™, SQL Server clusters, database mirroring, and log-shipping.
For complete descriptions of each of these HA solutions refer to SQL Server Books Online. Each solution synchronizes one or more copies of selected databases on alternate SQL Server installations. A manual or an automatic failover results in continued access for mission critical database applications.
