Back end servers provide the SQL databases used by Skype for Business, but do not run and Skype For Business functions SQL mirroring, clustering or always-on is recommended at the enterprise level. The front end servers are the core server roles, providing SfB functions. 

Edge Servers allow communication and collaboration to users outside the organisation's firewall. This can include offsite works, federated users and outside users included in conferences. There is also connectivity to public IM such as Skype.

Mediation Servers are used for translation between internal SfB infrastructure and a IP PBX, PSTN Gateway or a SIP trunk. This can be a standalone pool or run on the front end server.

A Director server does not hold any services or account and most useful in enhancing security by authenticating requests to prevent DOS attacks.
