I have a running EC2 instance. I would like to know all about cloning, starting with the obvious feature:
Right-click on the instance and find "Launch More Like This" ..
Is there any documentation anywhere? I have looked all over Amazon's developer documentation. Is this duplicating disk and memory, just disk, or just the raw AIM image for example? Thank you...
Launch more like this will launch another instance (or more) with the same settings as the selected instance (EBS, AMI, Security Groups, etc).
If you would like to launch an instance with the exact same data (basically a clone of the selected EC2 instance) you should create an AMI (in case of EBS backed instances, you can create an AMI by right clicking the instance in the Web Console) and launch instances with that AMI.
You can also create AMIs from previous EBS snapshots of your EBS device (also available from the EC2 Web Console).
