After a few recent conversations with CIO and CTO types, I was amazed that there is still the concept out there that SQL Server doesn’t scale well. So I sat down to write a lengthy blog to dispel that rumor. After doing some research, I found that there is so much already written and available on the web that I decided to gather all the links in one spot and make this blog a launching point for your own research and reading pleasure.
