I'm reading documentations of SQL Server. On this page at https://docs.microsoft.com/en-us/sql/sql-server/failover-clusters/windows/windows-server-failover-clustering-wsfc-with-sql-server, it says:
Both Always On Availability Groups and Always On Failover Cluster Instances use WSFC as a platform technology, registering components as WSFC cluster resources.
I'm a little bit confused. In previous version of SQL Server (like SQL Server 2008) there is a technology called SQL Server Failover Clustering, is it the same thing as Always On Failover Cluster Instances? Hope someone can clarify on this. Thanks in advance.
