Azure Blob Storage Pricing

Question

Kia ora team,

I am writing a cost articulation paper at work and am trying to figure out costings for when we add files to our ADLS. For a certain project, we upload 3 files per week on a Monday. We leave these in the data lake. Do we pay for uploading them (we are on a hot tier $0.0335 per GB) and then pay the same each month they sit there? So if we uploaded a file that was 1gb, would we pay $0.0335 to put it in the container and then pay $0.0335 each month to keep it stored there?

Thanks!

Hi Ueroa,

Yes, you are correct. When you upload a file to Azure Data Lake Storage in the hot tier, you pay for the storage cost based on the size of the file. For a 1 GB file, you would pay $0.0335 to upload it. Additionally, you will continue to pay $0.0335 per month for each GB stored in the hot tier

So, if you upload a 1 GB file, the cost breakdown would be:

• Initial upload cost: $0.0335
• Monthly storage cost: $0.0335 per month

Example, if you keep the file stored for 3 months, the total cost would be:

• Initial upload cost: $0.0335
• Storage cost for 3 months: $0.0335 * 3 = $0.1005

Total cost for 3 months: $0.0335 (upload) + $0.1005 (storage) = $0.134
