Probably a newbie question but something I've been wondering. If you host your site/app at host A and then your memcached nodes at host C, does not having the memcached nodes on the same network result in diminished value of using memcached in the first place?
Example: If someone uses Rackspace for the site/app, is there any point in using EC2 Elasticache? Or does having them on two different networks cancel out and benefits? Jeff
