A SQL Server high availability cluster is a configuration where multiple SQL Server instances are grouped together to provide redundancy and minimize downtime. In the event of a failure on one instance, another instance can seamlessly take over, ensuring continuous database availability. This is typically achieved through technologies like Always On Failover Cluster Instances (FCI) or Always On Availability Groups.
Here's a more detailed explanation:
