Applies To: Windows 7, Windows Server 2008 R2
This topic describes design considerations for DirectAccess in Windows Server 2008 R2. For the design considerations of DirectAccess in Microsoft Forefront Unified Access Gateway (UAG), see the Forefront UAG DirectAccess Design Guide (http://go.microsoft.com/fwlink/?LinkId=179988).
To design a scalable DirectAccess infrastructure, you must analyze the elements of a DirectAccess deployment and develop an implementation plan that considers several factors, including:
Performance. Which types of resources are most used by each server role in your DirectAccess deployment? How will you monitor performance?
Roles. Do servers in your DirectAccess deployment perform multiple functions? How does this affect performance?
Availability. Do you require 100 percent availability for all server roles in your deployment?
Access profile. When and where does your network experience peak activity? Is the activity consistent or does it change over time?
