This concept is very good. Kudos.

One of my scariest memories of getting hacked (back when I was a total greenhorn and cloud computing was rare) was hosting Wordpress blog on the same server as our main site. It got hacked bad. We had viagra links in all our files and it was a total nightmare to cleanup. Upon research I found out that there is an entire market of people trying to find WP hacks and sell it online. God knows how big it must be now.

Anyway, thankfully now you can just host your WP blog on an EC2/DO instance and eliminate all risks. But always keep your WP database and instance separate is what I learned from that.
