  <p>The db_model parameter I am passing is "db.t2.medium". The cluster gets created successfully in the cloudformation console however the AWS::RDS::DBInstance creation fails with the following error</p>
  
  <pre><code>"DeletionPolicy:Snapshot cannot be specified for a cluster instance, use deletion policy on the cluster instead." 
  </code></pre>
  
  <p>What's more weird that when I try to run the same CF template in say eu london region, it works fine!!! Is there something wrong with the EU ireland region and aurora?</p>
