This is roughly to number of IOPS that a single desktop-class 7200 rpm SATA hard drive can deliver. 1 Standard volumes deliver 100 IOPS on average.
In the EBS case, IOPS refer to operations on blocks that are up to 16 KB in size. Performance for EBS is primarily measured in input/output operations per second (IOPS). To optimize your EBS volumes for Provisioned IOPS, it is important to understand how it differs from Standard.
What AWS EBS Standard and Provisioned IOPS provide Although EBS Provisioned IOPS is the higher performance option, you get the best performance if and only if certain conditions (which are described below) are met. The two offerings differ primarily by performance, meaning that the speed of an application hosted on AWS using EBS for storage will be impacted by this choice. Gp3 is superior to gp2 and provides a better performance at or below the cost of gp2.Amazon Web Services (AWS) offers two flavors of networked block storage as a service with Elastic Block Storage (EBS): Standard and Provisioned IOPS. This shows that the gp3 volume had near or much better performance compared to gp2 at the same price. The gp3 volume reached its maximum provisioned capacity and performance with a cost of 1,380$/month, while the gp2 volume had cost of 1,600$/month. After that I couldn't maintain the cost differences to be zero. In parallel I increased the provisioned throughput using the remaining cost different till the gp3 volume reached the limit of 1,000 MiB/s. I gradually increased the provisioned IOPs of the gp3 volume to match the burst gp2 IOPs till it reached the limit of 16,000 IOPs at size 5.3 TiB. Now let's compare the performance if we are willing to invest the 20% cost difference in increasing gp3 performance. Except for small volumes, gp2 allows a much higher throughput. But gp2 provides much higher performance for bigger volumes. The graph shows that gp3 provides a higher consistent IOPS for volumes smaller than 800 GiB. On the other hand, the gp3 performance is consistent. As shown in the following diagram, the gp2 volume maximum IOPs can be anywhere within the thick orange line, the same applies for the maximum throughput (the blue line). Gp2 volumes performance depends on the volume size. The costs in this case are proportional to the provisioned volumes sizes, $0.10 per GB-month for gp2 volumes vs $0.08/GB-month for gp3. And we'll compare the performance for different volume sizes. We are keeping the performance of the volumes at the base default values. This can be increased up to $0.04/MB/s-month for provisioned throughput above the baseline.Īs the variables that control the performance and pricing of the two volume types are different and I splitter my comparison into the following two scenarios:
#Iops aws pricing free
Provisioned throughput: also a gp3 volume provides a baseline 125 MiB/s throughput free of charge.You can increase the allowed IOPs for your volume up to 16,000 and will be charged $0.005/IOPS-month for the extra. Provisioned IOPS: a gp3 volume provides a baseline 3000 IOPS (IOs per second) free of charge.PricingĪs of December 2020, in us-east-1 region, gp2 price is only based on the total provisioned storage, $0.10 per GB-month. So, 32 GiB or smaller volumes can't reach the 16,000 IOPs limit. Also, the maximum IOPs = (500) x (provisioned GiB). The maximum throughput that can be reached = (maximum IOPs) x (average IO size). Please note that gp3 volume size, IOPs and throughput still impact each other. Gp3 removed this limitation and you can increase the IOPs and/or throughput independently up to 16,000 IOPs and 1,000 MiB/s respectively. To get higher performance you have to use a bigger volume size. With gp2 volumes, you don't have direct control on the IOPs and throughput, they depend on the volume size. Throughput: the maximum amount of data that can be read/written per second.IOPS: the maximum number of Input and Output requests the volume can serve per second.PerformanceĪWS measures the volumes performance in two dimensions:
This post compares both types in terms of pricing and performance. It is the next generation of General Purposed block storage in AWS. Which is better, gp2 or gp3 EBS volume types?ĪWS announced the new SSD storage type, gp3, At AWS re:Invent 2020.
