Here's one easy (and cheap) way to do it. Server 1 is based on the the free tier on OpenShift. Server 2 is based on the free tier on Google App Engine (or Amazon EC2). On server 1 you install Apache, WordPress, Varnish and a file sync solution like syncthing. On server 2 you setup the DNS settings for your site plus the sync client. On server 1, you have WordPress use the Varnish plugin to automatically populate the Varnish cache with all pages on your site. Syncthing (or something similar, if syncthing doesn't work with GAE or EC2) looks at the Varnish cache folders and pushes all changes to Server 2. That's about all you need to do. It basically gives you a fast and hack-resistant WordPress website, and you only pay for the site domain name.
