My company is now migrating from on-demand Confluence to our own Amazon Cloud. We can get several different AMIs to do the job. The question is which wuld be the best one and most up-to-date?

The Amazon Linux AMI is assumed to be the latest - it is at the top of the list. Although, it has no Java (hence no jdbc) installed.
Ubuntu instance (second one marked) seems to be 3 years old and has everything pre-configured, but it says that Confluence License has expired.
Which AMI is the best for having the Confluence Server up and running without any issues?
