When creating a new instance on AWS using an official Ubuntu 12.04 server AMI, what differences are there compared to if I was to do a standard server install on a computer of my own?

For example, the default user is 'ubuntu'. An SSH public key is added to that users authorized_keys file. Sudo is passwordless for that user. PasswordAuthentication is disabled for SSH. etc etc.

Configurations have been changed from their defaults, and I'd like to know if there is a list, or somewhere I could find out the modifications made.
