Since the default Bamboo images for Elastic Bamboo contain all the build tools, it seems like those would be useful to install Bamboo itself so that a local agent will have all those tools. But no where do you list the valid current AWS images for Bamboo, and searching in marketplace yields none, and searching in community lists many that have no descriptions, and lack enough detail to know which is a likely valid candidate. All answers on this forum before are "select US-EAST and see them", well if you are using OnDemand maybe you can do that, but installing from scratch and searching you end up with a trash pile of options with no clarity. Provide some clarity, for current Bamboo, what is the AMI ID?
Later, maybe you can come up with naming convention of the AMI's to make this clear when someone DOES search for them.
