Estimating impacts of block storage
Block storage volumes are approximated either as SSD or HDD depending on cloud provider specific storage type.
This is a basic estimation. It takes into account the size of the block storage volume.
âš Only the manufacture impacts of the Block storage are returned. The impacts of the use phase are returned as zero (mainly because we lack the related data in current version of Boavizta API).
Block storage (EBS) estimation (AWS)
What is considered in estimation:
- storage type (HDD vs SSD)
- storage size
- duration of use
| AWS EBS volume type | Boavizta storage used for estimation | comments |
|---|---|---|
| st1 | HDD | |
| sc1 | HDD | |
| magnetic (standard) | HDD | |
| gp2 | SSD | |
| gp3 | SSD | |
| io1 | SSD | |
| io2 | SSD | |
| unknown type | SSD | If it cannot identify the type of storage (like when a new type is introduced, cloud scanner uses SSD as an approximation) |
What is not considered for the estimation
- If the storage offers provisioned IOPS or not.
- Implicit redundancy related to storage type.
- Any other infrastructure (network, backup, supervision or redundancy) that may allow the cloud provider to offer EBS service.
