An Azure service that stores unstructured data in the cloud as blobs.
@clearwatercompany Thanks for posting your query on Microsoft Q&A. If my understanding is correct, you are looking for billing impact for changing a blob's access tier.
Keep in mind the following billing impacts when changing a blob's tier:
- When a blob is uploaded or moved between tiers, it's charged at the corresponding rate immediately upon upload or tier change.
- When a blob is moved to a cooler tier, the operation is billed as a write operation to the destination tier, where the write operation (per 10,000) and data write (per GB) charges of the destination tier apply.
- When a blob is moved to a warmer tier (archive to hot), the operation is billed as a read from the source tier, where the read operation (per 10,000) and data retrieval (per GB) charges of the source tier apply. Early deletion charges for any blob moved out of the cool or archive tier may apply as well.
- While a blob is being rehydrated from the archive tier, that blob's data is billed as archived data until the data is restored and the blob's tier changes to hot or cool.
The following table summarizes how tier changes are billed.
Changing the access tier for a blob when versioning is enabled, or if the blob has snapshots, may result in more charges. For information about blobs with versioning enabled, see Pricing and billing in the blob versioning documentation. For information about blobs with snapshots, see Pricing and billing in the blob snapshots documentation.
Regarding your question about the cost for moving from archive to hot tier in blob storage for different region and subscription, it’s important to note that pricing varies by region and subscription type. I couldn't find a public documentation on this. I would recommend using the Get one-on-one guidance on Azure pricing service provided by Azure where you can request a pricing quote and get answers to your pricing questions via a chat session or a call.
You can also reach out Azure billing and subscription management team by creating a billing support request. Billing support request via Azure portal is free for all Azure customers and doesn't require a paid support plan. Please select 'Billin'g under 'issue type' while creating the support request.
