Brett Adam (pictured below), CTO and SVP/Engineering of rPath, discussed "the seven deadly sins" of cloud applications at the recent Cloud Expo in Santa Clara. The sins had much to do with lack of automation and focusing on infrastructure per se rather than the applications in your cloud.
One of them - "golden images in a cloud environment" - stood out among the rest. Brett was quite adamant during his presentation about the particularly heinous nature of this sin. I didn't quite grasp the significance of it, so I followed up with him on this point.
He remained passionate about this point in responding to my query. Here is his response:
"The issues with storing and managing images are many. Here are just a few:
* An 'image library' consumes large quantities of disk space, which only grows over time as new versions of images are created. Old images must be kept around for posterity since deployments may require any version, and audit and compliance may need them as well.
So now I've added "image sprawl" to my list of things to know about when it comes to deploying cloud computing. Who else has recognized this problem?
