Planning Federation Server Placement
The most critical component of an Active Directory Federation Services (AD FS) deployment is the federation server. Therefore, it is important that you plan your federation server placement strategy carefully, including when and where to deploy federation servers.

Although this information might help with your placement planning for federation servers, it does not explain how to determine the proper number of federation servers and the hardware requirements for each AD FS design.
For examples of how a federation server can be placed in any of the two primary AD FS design scenarios, see Mapping Your Deployment Goals to an AD FS Design.
