you should do it.
While it is "trivial" to do it for Sql Server, for a website it is not so trivial. If you have different domain and/or subdomain then may be you can runs in in a separated server but, usually 1 server is enough for a website application (since most of the work is done by the database). Also, it is possible to use a separated server for cache, for example memcached.
