I don't know about the security part, but to say that "The problem with LAMP is that it doesn't scale" or that "SEO bots take down your blog" is simply wrong.

I don't know about the security part, but to say that "The problem with LAMP is that it doesn't scale" or that "SEO bots take down your blog" is simply wrong. I host a WordPress blog in a $20 DO box and load time is about a second for a typical post (measured with tools.pingdom.com). This is a blog with more than 50.000 visits / month. NGINX, not Apache, but still.
