Question 31. How You’re Charged In Amazon Ec2? Explain In Detail ?

Answer :

  • Charges varies upon AMIs backed and storage volums.
  • AMIs backed by instance storage charged for: AMI storage + Instance usage
  • AMIs backed by Amazon EBS storage charged for: Volume storage + Usage in addition to the AMI + instance usage
  • When an Amazon EBS-backed instance is stopped, you are not charged for instance usage, but you are still charged for volume storage.
  • AWS charges a full instance hour for every transition from a stopped state to a running state, even if we transition the instance multiple times within a single hour.

For example: if hourly instance charge for your instance is $0.10 and if you were to run that instance for one hour without stopping it, you would be charged $0.10. If you stopped and restarted that instance twice during that hour, then you would be charged $0.30 for that hour of usage (the initial $0.10, plus 2 x $0.10 for each restart).
