Abstract: A patching operation on an availability group cluster having a plurality of nodes is disclosed. The patching operation is performed in a plurality of iterations, each including determining a current state of each of the plurality of nodes, selecting a next node based on the current state, and patching the next node. A secondary replica node is selected as the next node before the a primary replica node. Each secondary replica node is patched in accordance with a first priority, upon patching each of the secondary replica node, a failover target node for patching the primary replica node is selected, the failover target node is selected based on a second priority, and according to the second priority, a healthy synchronous secondary replica node of the plurality of nodes is selected as the failover target node before an unhealthy synchronous secondary replica node of the plurality of nodes.

Abstract: A system and method include creating, by an Availability Group (“AG”) controller in a virtual computing system, a first AG clone from a source database. The source database is stored on a primary replica node of an AG of the virtual computing system. The system and method also include creating, by the Controller, a second AG clone from the first AG clone and storing, by the Controller, the second AG clone on a secondary replica node of the AG. The second AG clone has a size of substantially zero
