Your company stores 20 TB of data in the archive tier for long term retention. However, after only three months in archive storage, 20% of that data must be retrieved for analysis. You've been asked to estimate what it will cost to get that data from archive storage and then download that data to clients for analysis.

Your company stores 20 TB of data in the archive tier for long term retention. However, after only three months in archive storage, 20% of that data must be retrieved for analysis. You've been asked to estimate what it will cost to get that data from archive storage and then download that data to clients for analysis. Because the data is needed only temporarily, you decide that it's best to rehydrate blobs by copying them to the hot tier. That way, your company avoids the early deletion fee. After the data is no longer needed, it can be deleted from the hot tier at no charge.
