When mentioning the word cluster, people generally have one idea in mind when it comes to SQL Server – clustering the instance itself (also known as an FCI). However, Microsoft changed the game by introducing availability groups (AGs) which also require an underlying Windows Server failover cluster (WSFC). This has created a lot of confusion for DBAs and implementers alike. This session will clarify both the similarities and differences between these two major availability features as well as provide some practical deployment tips. Windows concepts will be front and center and discussed in context of implementing both AGs and FCIs.
