Spot instance for testing

Question

I'm running a Java application on an EC2 instance (RHEL). It has only 8GB RAM that's not enough to test some stuff. Can I take an image of this machine, request a spot instance using this image, and test it? I only need it for a few hours. Is it possible?

Answer

Hello.

It is possible to create an EC2 AMI that is currently running as an On-Demand Instance and then create a Spot Instance from that AMI.  
Once you have created your custom AMI, request a Spot Instance using the steps in the documentation below.  
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/spot-requests.html#using-spot-instances-request

If there is no free space in the specified Spot Instance capacity pool, you may not be able to start the Spot Instance, so in that case, you may want to start an On-Demand Instance and delete it after the test is completed.
