![]() So, constantly check and delete any unwanted EBS volumes.Ģ. Simply set ‘ DeleteOn Termination ’ attribute for additional non-root EBS volumes to ‘true’. Note : You can set your EC2 to automatically delete the EBS root device volume upon EC2 instance termination. You must delete a volume to avoid incurring further charges. After you detach a volume, you are still charged for volume storage if the storage amount exceeds Amazon’s Free Tier limit. Also look at network throughput and IOPS to see whether there was any volume activity over the past few weeks. Check for volumes that have the AWS attribute named “state” set to the value “available”, which are not attached to an EC2 instance. When EC2 instances are terminated, attached EBS volumes are not automatically deleted and will continue to charge since they are still operating. Find detached EBS Volumes in terminated EC2 instances At higher volumes, GP3 still remains cheaper though the difference reduces to about 5% at around 7 Terabytes of capacity.Ĭosts of GP2 vs GP3 while maintaining the same level of performance (savings are show on right axis)ġ. ![]() This is due to the costs of provisioning additional GP3 performance beyond 3,000 IOPS after 1 Terabytes of capacity. ![]() The graph below starts with a 20% differential savings that goes down as the provisioned capacity increases on the x-axis. So a fair comparison between the two must take into account the additional costs of GP3 performance to match the increasing performance of GP2 as the provisioned storage capacity grows. Adding throughput costs $0.04/ MB/s-month.Adding provisioned IOPS costs $0.005/p IOPS-month.A value of using GP3 is that you can provision its throughput and IOPS independently from its storage capacity to obtain a consistent level of desired performance, based on the following rates: GP2 also uses the concept of “burst credit” to burst for up to 30 minutes beyond its baseline IOPS, which doesn’t apply to GP3. However you must keep in mind that GP2’s performance is proportional to its volume capacity, so to have higher performance, you must provision a volume with higher storage capacity. ![]() The storage cost of gp3 is on average 20% less than gp2 ($0.08/GB-month vs $0.1/GB-month of GP2) for smaller storage volumes.
