I have a bunch of webservers which connect to databases directly (2tier). I need to go multi tier to remove the security issues associated with direct db links to systems from outside the firewall... What's the best way of accomplishing this, given that I don't have dedicated app servers, i guess...
Is it a standard practice that the raised floor and false ceiling height should be more than 2 feets for Tier 3 Data Center. Will it have any impact on power utilisation?
What are Tier levels and their descriptions? What difference does a tier have to operations?
