Here is a simple bash script that you can use to change all gp2 volumes to gp3 volumes using the AWS CLI: #!/bin/bash #Get all the gp2 volumes GP2_VOLUMES=$(aws ec2 describe-volumes -filters "Name=volume-type,Values=gp2" -query 'Volumes.') #Loop through all the gp2 volumes for volume in $(echo $GP2_VOLUMES | jq -r '. aws ec2 modify-volume -volume-type gp3 -iops 4000 -throughput 250 -volume-id The following is an example command to modify a gp2 volume to gp3 and configure specific IOPS and throughput. Where is the Volume ID that you want to migrate to gp3. Use the modify-volume command so you migrate to gp3: aws ec2 modify-volume -volume-type gp3 -volume-id Use the describe-volumes command with the -filters option to get a list of all gp2 volumes: aws ec2 describe-volumes -filters "Name=volume-type,Values=gp2"Ģ. (Optional) Before modifying a volume that contains valuable data, it is a best practice to create a snapshot of the volume in case you need to roll back your changes.To select the right size and right performance parameters (IOPS, throughput) that can provide you maximum cost reduction without affecting performance, I recommend reviewing the IOPS and throughput suggested by Sibasankar Behera on his blog post.For example, if you modify a 500 GiB gp2 volume with 250 MiB/s throughput and 1500 IOPS to gp3 without specifying IOPS or throughput performance, Amazon EBS automatically provisions the gp3 volume with 3000 IOPS (baseline gp3 IOPS) and 250 MiB/s (to match the source gp2 volume throughput). If you change the volume type from gp2 to gp3, and you do not specify IOPS or throughput performance, Amazon EBS automatically provisions either equivalent performance to that of the source gp2 volume, or the baseline gp3 performance, whichever is higher.You can’t modify multiple volumes at once.Modify volume details (Size, IOPS and Throughput) When prompted for confirmation, choose Yes. After you have finished changing the volume settings, choose Modify.To modify the throughput, if the volume type is gp3, enter a new value for Throughput. To modify the IOPS, enter a new value for IOPS.ĭ. To modify the size, enter a new value for Size.Ĭ. To modify the type, choose gp3 for Volume Type.ī. Set new configuration values as follows:Ī. The Modify volume window displays the volume ID and the volume’s current configuration, including type, size, IOPS, and throughput.Select the volume to modify and choose Actions, Modify volume.Identify all gp2 volumes by applying the following filter: “Type = gp2”.In the navigation pane, choose Volumes.To modify an EBS volume using the console: Find and Migrate gp2 volumes via AWS Console Migrating EBS volumes from gp2 to gp3 can be done via AWS console or AWS CLI without the need to restart your instances or detach your volumes. Virginia) Region (detailed pricing examples are available here):ĮBS gp2 to gp3 migration cost saving calculator How to Find and Migrate gp2 volumes to gp3 volumes Here is a quick comparison of cost between gp2 and gp3 volumes in the us-east-1 (N. By migrating from gp2 volumes to gp3 volumes without restarting instances or detaching volumes, customers can achieve cost reduction on their monthly storage spend. Furthermore, gp3 volumes can be scaled up to 16,000 IOPS and 1,000 MiB/s for an additional fee, making it 4 times faster than maximum throughput of gp2 volumes. Additionally, with gp3 volumes, customers can provision IOPS and throughput independently, without increasing storage size, at costs up to 20% less per GB compared to gp2 volumes. gp3 volumes provide predictable performance of 3,000 IOPS and 125 MiB/s, regardless of volume size. To address this issue, AWS introduced a new Amazon EBS General Purpose SSD volume type, gp3, in December 2020. This can lead to over-provisioning of storage or performance, which is not cost-effective. Increasing volume size comes with increased cost too. However, the performance of gp2 volumes is tied to their provisioned size, which increases linearly with the volume size. General Purpose SSD (gp2) Amazon EBS volumes are a cost-effective way for AWS customers to access SSD performance for a variety of applications, such as virtual desktops, medium-sized databases, development, and testing environments. In this hands-on guide, we’ll show you how you can migrate your EBS gp2 volumes to gp3 to lower your AWS disk costs by up to 20%.
