It looks like a nice start. I was a bit confused by one bit though; "but to make it work you’ve got to start thinking about how to share data between the publisher and admin components - the data that your website publishes, and your sessions too." I don't understand why you would need to share sessions. You wouldn't need to share sessions for the users becuase they should never interact directly with the database/admin server. You could share admin sessions between both servers but you wouldn't really *need* to do so. Am I missing something?

James, the performance implications are worth considering. If the admin function causes a lot of disk i/o, for example, or is unusually memory-intensive, that can stop the database server software from running well. Best regards, Stu Thanks everyone.

One question - are the performance implications of running a web server (albeit mostly idle) on the DB box in a two-tier setup for the admin worth considering? Great article Stu.
