I deleted an EC2 (AWS) instance but after 5 minutes it re-created automatically with same name but different ID.
How is possible that?
How can I delete the instance, so will not be created again..
Below is screen short, I delete instance with name pclub, but it has created again..

This magic must be happening from an auto-scaling group in your environment. Check whether there is a scaling group and what is the minimum number of instances configured.
