The typcial intranet/internet application we look after is three tier.  So you have:

Web server connects to transaction server which retrieves content from the database/data server.

Now at the moment, you’ll have typically some medium/small web servers which use similar web servers to connect to something very powerful to handle/store your data.

With the bladecenter, you could have the first two tiers in blades, the web site getting too many hits because your sites’ doing great business, fine, deploy another blade, and have your web support team divert traffic, the transaction time increasing, plug in another blade and add it to the farm.

Obviously there will be the cross charging, the how do we do this, but if we get passed this and work out how we can deliver a scalable/computing on demand type platform.
