Security Groups in AWS

Need to group them!
Just discovered that it isn't possible to move a created AMI from one security group to another security group after its initial creation. This is not too helpful as many organisations probably have a fluid and organic idea over the concept of AWS Security groups and will wish for some flexibility once they have been created.

Losing an AMI is also very easy to do!

Naming and identifying AMI
We've also decided to refer to our AMI using the last three digits of their unique instance id (example: '27b' or 'f4f') as a quick and easy way to identify them. There is room for confusing still between 'instance' and 'ami' but we'll sort this out when we get to it.
