In the previous chapters, we mentioned that Always On solutions leverage the Windows Server operating system and Windows Server Failover Cluster (WSFC) as a platform technology. For a given Always On Availability Group, the availability replicas must be hosted by separate instances of SQL Server running on different nodes of the same WSFC. Availability groups rely on WSFC for health monitoring, failover coordination, and server connectivity. Hence it’s crucial that SQL Server database architects and administrators have a better understanding of WSFC.
