Firstly, AlwaysOn is a marketing term, not a feature. The two features are Always On Failover Clustering and Always On Availability Groups
I'm going to assume you mean Availability Groups, because Failover Clustering is available in Standard Edition.
Will your VMware solution allow readable secondary copies of the database?
Will it allow for complete failure of the storage array and still work?
Will it allow for an uncontrolled failover in a matter of seconds?
Will it allow for a synchronous copy of the database to be in a secondary data centre in case the entire primary data centre fails?
Will it automatically repair corrupt data pages?
Will it allow you to offload full and log backups to the secondary copy?
Will it allow for failover of individual databases or groups of databases?
