I got a bill form Amazon charging me $1.20. for $0.12 per GB-month of General Purpose (SSD) provisioned storage - US West (Northern California)? They said I used 10.000 GB last month but I haven't done a single thing with AWS. How is this happening and how to I stop this from happening again?
Have you checked your Elastic Block Storage - Volume inside EC2 Web Console? Maybe there is something left inside there. It's your SSD volume.
