Jekyll with GitHub Pages is a great solution, but it's worth mentioning that other static site generators serve the same purpose and may be a better fit for you, depending on your preferences. Hyde is a very flexible static site generator based on Django, and Metalsmith is a very promising static site generator built on Node. Whatever static site generator you use, hosting on S3 is easy and cheap, and it's easy to automate deployments via Grunt or Gulp.
