SharePoint AAM is deprecated , really ?

If you read following artile you may be confused.

“Because the features of alternate access mapping are deprecated, we recommend that you use host-named site collections over alternate access mappings.”

First it is not true !!!  For path based site collections you will use AAM because you have no other possibility. So basically this sentence not aims directly to SharePoint 2013 on-premise solutions.In SPO yes in SPO architecture based on Host named sites collections and AAM usage not necessary but this is not configurable by customers anyway in SPO .I hope, this article will be changed soon . You be sure that AAMs will be around for a long time.
