Who it suits.

Workloads already on Azure, where keeping storage in the same region as the compute avoids the bandwidth charge that dominates an object storage bill.

Consider something else if…

Egress is charged beyond the first 100 GB a month, where R2, Wasabi and Tigris charge nothing — and Azure's rates vary by region and redundancy, so a quoted figure only holds for the combination it was read for.

What the documentation says.

Each value below links to the page it was read from, with the sentence it came from. Criteria Azure Blob Storage does not publish are not listed.

Pricing

Pricing model

Per region, per redundancy and per access tier, with storage, operations and bandwidth metered separately. Rates are published in Azure's public Retail Prices API rather than only on a pricing page, so a figure can be re-verified exactly rather than re-read.

Egress over allowance

First 100 GB a month free, then $0.087 per GB over Microsoft's global network, falling to $0.083 above ~10 TB, $0.07 above ~50 TB and $0.05 above ~150 TB. Routing over the public internet instead is $0.08 at the first tier. This is Azure-wide bandwidth rather than a Blob-specific charge.

Limits

Storage (entry plan)

None. Azure Blob has no plans and no free storage band: the Hot LRS storage meter's cheapest tier begins at tierMinimumUnits 0 and charges $0.0208 per GB-month from the first gigabyte, with volume tiers only above 50 TB. Azure's free account offer sits outside the rate card and is time-limited, so it is not an allowance this criterion can record.

Minimum storage duration

None on Hot. Cool carries a 30-day minimum, Cold 90 days and Archive 180 days — the longest early-deletion window of any provider here, and three times S3's 90-day Glacier figure.
