title: Choosing gems to work with AWS
body: <p>Suppose a service written with RoR starts to use AWS S3 to store some data. What is the best library to use for working with AWS S3? Currently the main two alternatives for me are:</p>
  
  <ul>
  <li>RightScale AWS Ruby gems
  <a href="http://github.com/rightscale/right_aws" rel="noreferrer">http://github.com/rightscale/right_aws</a></li>
  <li>AWS::s3 <a href="http://amazon.rubyforge.org/" rel="noreferrer">http://amazon.rubyforge.org/</a></li>
  </ul>
  
  <p>What are their main advantages and disadvantages? What if later service will need to use other AWS (like EC2)? What other gems do you use and why?</p>
  
  <p>Thanks!</p>
