title: AWS OpsWorks vs CloudFormation
body: <p>I want to understand the <strong>exact limitations of OpsWorks</strong>- things that we simply may not be able to do or not optimally. That would require to go to the next level - CloudFormation.  Of course we can use OpsWorks + CloudFormation - get best of both worlds - a best practice. </p>
  
  <p>Some limitations of OpsWorks that  I am aware of are - it cant provision everything - like EMR, S3 etc - but have <em>never found on exhaustive list</em>. Also OpsWorks the AutoScaling configuration has limitations. And CloudFormation lets us version control the environment unlike OpsWorks. Do understand that there is good amount of overlap and CloudFormation does add to complexity.</p>
  
  <p>There was a <a href="https://stackoverflow.com/questions/21310125/aws-opsworks-vs-aws-beanstalk-vs-aws-cloudformation">previous discussion</a> but the demarcations were not made clear.</p>
