Elasticfox
Anyone interested in working with Amazon EC2 should definitely consider the Elasticfox extension for Firefox. It makes the whole thing a breeze and infinitely more accessible than working with the command-line tools.
The only immediate problem with it is the lack of documentation. Thankfully, some helpful users have gone a long way to addressing this by contributing their own instructions.
It’s also worth noting that the EC2 Getting Started Guide still makes reasonable sense when using Elasticfox rather than the command-line tools.
