non-hardware related failovers in dedicated SQL Server boxes?

In a Microsoft Cluster, what can cause a failover (other than hardware resources)?
In a SQL Cluster (SQL 2012-High Availability), is it the same as Microsoft Cluster in terms of what can cause an actual fail(over)?

Since SQL Server 2012 that you have an option to use AlwaysOn feature that get rids of the single point of failure of storage since it won't use shared storage. AlwaysOn it's only available in Enterprise Edition.

Do you see all or most failures related to hardware only?
of the below, some are performance based, like CPU utilization, and still hardware based. what could be non-hardware related failures?

Other than this, are all other vulnerable aspect of failure the same between the 2 methods (ms cluster & AG)?

The same as per a stand-alone installation.

AG is different from MSSQL Failover Cluster. AG is an advanced mirror solution that allows read only access to replicas. AG intended to have a faster failover from primary to secondary replica.

Mostly everything you can think of. Remember that it's an application running on a operating system installed in a computer. So things like bugs, viruses, misconfigurations, compabilities, etc, need to be taking in consideration.
