Today on the PDC, Microsoft also announced "Whitehorse" which will also be a part of Whidbey. "Whitehorse" will assist in making enterprise deployment of SOA applications easier. A network administrator will design the datacenter layout and specify restrictions set on each part of the datacenter. For example, he can defined that webservers in the DMZ do not allow XML web services installed on it. Another example: he can define that internal application servers must use Impersonation for their data access. The solution architect on his side, specifies which parts of a solution must be installed on specific servers. If there is a conflict between the datacenter restrictions and the solution, Whitehorse will identify it during architecture and solve the issue itself if possible.

There is probably a lot more to know about Whitehorse, but it seems promissing that developers and IT Pro's will be able to work together in a constructive manner for deploying applications in the datacenter.
