At roughly $30/month minimum for the "basic" service (that doesn't auto-scale), plus costs for add-ons, you really have to not know what you're doing when it comes to deployment (or just have money to burn), because PHP/MySQL is just about the easiest thing to deploy in the world.
But having auto-scaling on your app, I could see this being worth the value if you want that kind of stuff to be managed for you.
