From Microsoft's Failover and Network Load Balancing Clustering Team Blog :
We’ve had a lot of requests for a centralized website to find clustering and high-availability information and…it’s coming soon. J But in the meantime I’ll post some great resources from Microsoft’s Clustering and High-Availability team.
I’ll try to update this list when we get a few more. We have several coming out in the near future (including Active Directory considerations).
