Oh , thanks for you reply.

I learn alot from you, as you seems to be a DB admin or developer, and I am in networking 🙂

I didn't know about azure.

I searched about it. But found this:

.I also learned alittle about cloud computing. Can SQL be integrated with some cloud computing environments like VMSphere?

What I meant about clustering and partitioning was something completely different from azure and cloud computing.
