The Infrastructure Planning and Design guides are the next version of Windows Server System Reference Architecture. The guides in this series help clarify and streamline design processes for Microsoft infrastructure technologies; each guide addressing a unique infrastructure technology or scenario. All guides share a common structure including:
These guides complement product documentation by exposing and focusing on infrastructure design options. The Infrastructure Planning and Design Beta Program is ongoing and will showcase multiple Beta release waves to support virtualisation and Windows Server 2008 technologies in the coming months. Future plans will extend the architectural guidance to additional Microsoft operating system and software technologies. The following guides are available for Beta review and we welcome your feedback. You may need to sign in with your Windows Live ID to access these resources.
