Cost structure for io2 volumes

When considering io2 volumes for your high-performance storage needs, it's essential to understand the pricing structure. AWS employs a pay-as-you-go model, meaning you only pay for the resources you provision. For io2 volumes, the cost is calculated based on three main components:

  1. Storage: You're charged for the amount of storage provisioned.
  2. IOPS: Costs are associated with the number of IOPS you allocate.
  3. Throughput: For higher performance needs, additional charges apply for increased throughput.

Here's a simplified breakdown of how costs are calculated:

Component Calculation Method
Storage (GB provisioned) x (Hours in the month) x (Price per GB-month)
IOPS (Provisioned IOPS) x (Hours in the month) x (Price per IOPS-month)
Throughput (Provisioned throughput above baseline) x (Hours in the month) x (Price per MBps-month)

Regional availability

io2 volumes, including io2 Block Express, are available in various AWS regions. However, availability may vary, so it's crucial to check the AWS documentation for the most up-to-date information on regional support. This ensures you can plan your infrastructure deployment effectively based on your geographical needs and the availability of io2 volumes in your preferred regions.

Comparison with pricing of other EBS volume types

To help you make an informed decision, let's compare io2 volumes with other EBS volume types:
