IIS7 in Windows Server 2008 R

"For the last year and a half, the IIS product team has been working hard on building IIS extensions on top of the IIS7 platform, releasing betas, RCs and RTWs that add new support for optimizing media hosting, web content publishing, site and server administration, deployment and migration, and request handling. We would not be able to innovate and build production-ready, fully supported MS software in 12-18 months like this without the architectural changes we introduced in IIS7 in Windows Server 2008. Now with Windows Server 2008 R2, we have added some improvements, fit and finish to that IIS7 platform."
