A brief summary of pricing for Object Storage services from AWS, Azure and GCP providers
The storage we want is just for backup, so theoretically we won't need access, and even if we do, instant access won't be necessary. So we will use this storage in the cheapest region. In this case: US East (N. Virginia)
Before talking about spending on AWS, we must first raise the reasons why we will be charged. In our case:
- Storage
- Requests
- Data tansfer
Storage is billed monthly based on the amount of storage and the storage class. Here are the two classes that best fit our case:
- S3 Standard - Infrequent Access - For long lived but infrequently accessed data that needs millisecond access
- S3 Glacier - For long-term backups and archives with retrieval option from 1 minute to 12 hours
- S3 Deep glacier - For long-term data archiving that is accessed once or twice in a year and can be restored within 12 hours
| Storage Class | Cost / GB / Month |
|---|---|
| S3 Glacier | 0.0036 |
| S3 Deep Glacier | 0.00099 |
| S3 Standard - Infrequent Access | $ 0.0125 |
Requests are billed based in the number and type of requests:
the only type of request we will not be charged for will be delete requests, for the other types:
| Storage Class | PUT, COPY, POST, LIST | GET, SELECT | Data Retrieval requests |
|---|---|---|---|
| S3 Glacier | 0.03 / 1k requests | 0.04 / 1k requests | $ 0.05 / 1k requests |
| S3 Deep Glacier | 0.05 / 1k requests | 0.04 / 1k requests | $ 0.02 / 1k requests |
| S3 Standard-InfrequentAccess | 0.01 / 1k requests | 0.01 / 1k requests | n/a |
For archiving classes there is an additional cost to unarchive:
| Storage Class | Data Retrievals |
|---|---|
| S3 Glacier | 0.01 / GB |
| S3 Deep Glacier | 0.025 / GB |
S3 Standard-Infrequent Access is not a class to archive, so it does not apply.
The only expected expense that fits our use is transferring data from S3 to the Internet, which will cost approximately 0.09 per GB
Similar to AWS, GCP will also charge us through the amount and class of storage:
- Archive storage: for data archiving, online backup, and disaster recovery with data availability in milliseconds
| Storage Class | Cost / GB / Month |
|---|---|
| Archive storage | 0.0012 |
| Storage Class | PUT, COPY, POST, LIST | GET, SELECT |
|---|---|---|
| Archive storage | 0.05 / 1k requests | 0.04 / 1k requests |
For archiving classes there is an additional cost to unarchive:
| Storage Class | Data Retrievals |
|---|---|
| S3 Deep Glacier | 0.05 / GB |
The only expected expense that fits our use is transferring data from CS to the Internet, which will cost approximately 0.12 per GB.
- Archive: The archive tier is an offline tier for storing data that is rarely accessed. The archive access tier has the lowest storage cost. However, this tier has higher data retrieval costs with a higher latency.
| Storage Class | Cost / GB / Month |
|---|---|
| Archive | 0.00099 |
| Storage Class | PUT, COPY, POST, LIST | GET, SELECT |
|---|---|---|
| Archive storage | 0.13 / 10k requests | 6.50 / 10k requests |
For archiving classes there is an additional cost to unarchive:
| Storage Class | Data Retrievals |
|---|---|
| S3 Deep Glacier | 0.02 / GB |
The only expected expense that fits our use is transferring data from Azure to the Internet, which will be free for the fist 100GB after that will cost approximately 0.08 per GB.
