I was hoping to get some advice here on a web hosting query. We are building an eCommerce website that will basically reside on 2 x web servers (fronted by a load balancer) and interacting with a SQL2008 cluster.
In dealings with web hosting companies, some are trying to sell us an additional box which will be used as a domain controller. They claim that it's better design. Of course, the costs go up accordingly as well.
I want to better understand this - does the DC offer us better support from a security perspective. If we don't have this, what do we risk losing?
