What are the cons of not federating a server

[RenatoSalvaleon]

Most of the documentation I see is what federation can do and its pros but what do I miss if I don't federate my server.

You could check the comparison among different levels of integration of ArcGIS Server site and Portal for ArcGIS, i.e., No Server Integration/ with Federated Server (No Hosting Server)/ Federated with Hosting Server.

There's no "hosting server" without being federated?

From what I have experienced, the symbology is not as good.  It makes it have the same rules for symbology as AGOL.  So if you have a solution that is internal that uses rest services you will be limited on the symbology if you federate.
