This plugin captures all pages of your blog and uploads them to Amazon S3. This way you can host your blog as a static page for very little cost.
Before you run your blog this way, make sure that you are not using any functionality that isn’t static or replace it with a service. For example: 
 – disable comments or use Disqus plugin instead of standard commenting system 
 – disable search 
 – use Google Forms for contact form 
 – etc.
To publish new content, you will have to run your server with WordPress, write new post and then run the plugin again to create new files. For that purpose it is best to run WordPress on your local machine or to make an EC2 instance in Amazon cloud and run it only when you are updating your blog.
