Question 48. What Is A Placement Group In Ec2 ? Answer : AWS provides an option of creating a Placement Group in EC2 to logically group the instances within as single Availability Zone. We get the benefits of low network latency and high network throughput by using a Placement Group. Placement Group is a free option as of now. When we stop an instance, it will run in same Placement Group in restart at a later point of time. The biggest limitation of Placement Group is that we cannot add Instances from multiple availability zones to one Placement Group. Question 49.

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).
