David Kimura  Thank you so much for this episode! This is so helpful and I am grateful to be part of your subscriber. Please allow me to ask you 1 question. If you want to build multiple clusters of web servers specific to different functions, how would you do? For example, Web Server Cluster A is for customer facing pages, and Web Server Cluster B is for Admin pages. I appreciate a lot for your insight in this, when you have time to reply.
