learning aws is not cheap

 I started studying on aws and created an account just to create and delete resources, I thought deleting free tier instance will stop amazon to charge me, but after all they manage to charge me from something else, and I did not check until now

looks like EC2 but I did not have any instances running then I found

 

elastic ip address, did not know that I had that, even though I deleted instance they hold the ip under my account, weird
