object storage pricing
Understanding cloud pricing is pretty tricky. This post focuses on the projected costs of storing backup data in an s3 compatible object store.
I will show that scaleway object storage is much better value than aws or backblaze (b2).
Here is a breakdown of the $ USD / month cost of each provider, and their storage tier.
Note; aws and b2 prices are in USD, scaleway use EUR. I converted the EUR to USD on 16th Feb 2021.
|provider||$ / GB in standard||$ / GB in glacier||standard free tier (GB)||glacier free tier (GB)|
*b2 doesn’t have storage tiers
The following charts are based on these parameters;
- 100GB initial upload
- 10GB added each month
- Transition to glacier tier after 2 months
- Cost is projected for 48 months (4 years)
Cumulative cost chart
Monthly cost chart
In the monthly cost chart, we can see a jump in pricing at the beginning, because it takes 2 months
for our data to be transitioned to the
glacier tier. We chose 2 months, as after this amount of
time the data is highly unlikely to be needed. Restoring backups are likely to be from more recent
|provider||total $ @ 12 months||total $ @ 24months||total $ @ 48 months|
Charted, this table looks like;
scaleway is clearly the best value for money
Scaleway is clearly the best value for money.
- Scaleway is ~2.88x cheaper than aws
- Scaleway is ~2.63x cheaper than b2
In real terms, this means you can add ~1.5TB (1500GB) to scaleway over the 48month term and pay the same price as if you had added just 480GB to aws.
Scaleway is the best value because it includes a generous free tier on both
storage tiers. B2 appears cheap in it’s price / GB, but it doesn’t have a
glacier product, which
means you pay standard pricing for all your data (this really adds up)!
cost depends on usecase
I have analysed the costs for a backup usecase, that has infrequent access to a growing proportion
of the data. If the usecase was a object store where all the data was accessed frequently, then b2
would be the cheapest, as it’s
standard tier price is about half that of scaleway and a fifth of
