VMWare was very good for simulation of different types of issues but also had a lot of problems. It is hard to simulate real systems using virtual machines and virtual machines are very easily corrupted so you need to ensure you backup your information very frequently.

Also sharing any way limits you to resources of single server - dedicated physical web and database box will surely have more power. Michael,

To me the separate physical web server on one box and database is a better idea, but some people keep on recommending this to me.

It scales linearly only from the first glance. In reality it has problems with scaling writes (you mention it already) second as database size grows it may change from CPU bound workload to IO bound workload which slows things down dramatically. This is not to mention conflicting updates and complicated failure recovery for circular replication. In general I can only see it used then conflicting updates are not an issue and application can't be made aware of multi server configuration. John,

This will (in principle) scale linearly with number of boxes, until propagation delays become problematic (but less of an issue if using sticky sessions). Useful for read-heavy apps.
