I'm looking to set up a new server on Amazon's EC2 and I wanted to use Ubuntu 11.04 is it is fairly new but not too new. I previously used 10.10 which I think is also very stable and time-tested.

My problem is that when I run ec2-describe-images -o amazon (get images owned by amazon) none of these are Ubuntu. If I run ec2-describe-images -a (get all images) there are about 12k images.


  1. Is there a reason Amazon doesn't have ubuntu images available?
  2. If you were running ubuntu on a production system, would you choose 11.04? If not, what version would you choose and why?
  3. How do I select a good ubuntu image from the list? With 12k images how do you vet them? Is a particular one endorsed or created by Ubuntu?

    For #2, I'd go with the latest Long Term Support (LTS) version - that is 10.04. The reason is that companies that create software for Ubuntu provide support for the LTS release at a higher priority than other releases, and Canonical has committed to resolving bugs in the LTS release for a longer duration. – Hippo Nov 11 '11 at 16:30
  • That's helpful. Where is the latest LTS version documented? – cwd Nov 11 '11 at 16:36

    LTS versions are released every two years. The Ubuntu Wiki has a helpful page on this at wiki.ubuntu.com/LTS. – Hippo Nov 11 '11 at 16:52

Ubuntu's Wiki

As @Hippo mentioned you can look at the LTS page which has this chart:
