Canonical Software, which administers the popular Ubuntu distribution of Linux (and my personal favorite), recently announced improved support for Cloud computing in the upcoming release 9.10 , named Karmic Koala. In particular, Ubuntu will be available as a pre-packaged AMI, or Amazon Machine Instance, for convenient deployment on Amazon’s EC2 cloud. During a recent hands-on workshop on Amazon EC2 at SCaLE I noticed a potential security risk inherent in the large number of uncertified server images proliferating as “community AMI’s” on EC2. It’s not a good idea to build a production server, or even a dev server which may later be thrown into production, on an unknown image, just as you wouldn’t use a CD-R from a random stranger to build your new server. Good to see Canonical and Ubuntu moving forward with this initiative, the open-source community needs to take more leadership with emerging cloud technologies.
