Hi, I'm interested in installing WordPress on AWS. I'm thinking about using theTurnKey Linux AMI, but I have a few questions:

• What are the advantages of the TurnKey Linux AMI over AWS CloudFormation templates? From the website I've gathered that automated backup and updates and firewall configuration are the two main advantages. Is there anything else that I'm missing?
• Is there any reason to prefer the 32-bit AMI over the 64-bit version?
• Are there any performance issues I should be aware of? My primary concern is speed.

Thanks in advance.
