Is it possible to resize an Amazon EC2 instance, e.g. convert from a small instance to a large instance? If so, what is the easiest way to resize Amazon EC2 instance?

Like Rackspace Cloud Servers do with Rebuild (see http://i.stack.imgur.com/F7rjF.gif).

  • My instance uses EBS.

  1. In your AWS Management Console, go to the EC2 Tab.
  2. Check the instance you want to change (from micro to large, for example)
  3. Put the instance in a 'Stopped' state.
  4. Click the 'Instance Actions' menu, and choose 'Change Instance Type'
  5. Choose the level you want the instance to run at (small, medium, large)
  6. Click 'Yes, Change'.
  7. Restart the instance in question.

And what if I want to go from micro to large instance? Creating AMI is the only way? –  Randy Hoff Dec 28 '10 at 21:47
I assumed you were talking about resizing the image. You can stop a machine and start it on any size instance that has space. alestic.com/2010/05/ec2-move-ebs-boot-instance –  Jeff Ferland Dec 28 '10 at 21:51
