Best way to deploy a Storm cluster on AWS EC2

[Rahul Patil at Amazon]

Hello folks,I see at least 3 tools that can be used to deploy a Storm cluster 
on EC2.  
1. Storm deploy   : https://github.com/nathanmarz/storm-deploy 2. Wirbelsturm   
 : https://github.com/miguno/wirbelsturm3. Storm deploy alternative   : 
https://github.com/KasperMadsen/storm-deploy-alternative 
If you have used any of the above tools, can you share your experiences?  Are 
there other tools you would recommend? Any gotchas with deploying Storm 
applications that also use AWS SDK?
Thanks in advance!Rahul
