SQL Failover cluster - Best practice on connecting from an application

    We have a SQL 2019 Failover Cluster Instance - Default Instance. Question seems lame but...

    My question is, what is the "Best Practice" on connecting? Directly to the SQL Cluster name? Or some want us to create a DNS Alias to that SQL Cluster Name, is that best practice or even a "supported" way??

    I think "Best Practice" is to connect to the SQL Cluster Name, but I can't find any links on the matter.

    Does anyone know or have links?

    Thanks

    We mostly use DNS aliasses to have applications connect to our clustered instances.

    ( more meaningful naming conventions as with our server names )

    Doing so, we can migrate the sqlcluster without having to modify the application. ( only modify the dns alias )

    ( of course after intensive testing on an isolated environment )

    Are you using an Availability Group, or Windows clustering?
