# Azure Blob Storage

Canonical: https://inetgeek.com/storage/azure-blob/

Microsoft's object storage, priced per region — every figure here is East US Hot LRS from the public retail price feed.

## 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

### 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.

### Storage

- Storage price: $0.0208 per GB-month for Hot LRS in East US, falling to $0.019968 above 50 TB and $0.019136 above 500 TB. Azure prices vary by region and redundancy; this and every Azure figure on the site is East US, locally redundant. ([source](https://prices.azure.com/api/retail/prices), read 2026-09-06)
- Operations price: $0.05 per 10,000 write operations and $0.004 per 10,000 reads on Hot LRS — $5.00 and $0.40 per million. Listing and creating containers is $0.05 per 10,000; all other operations $0.004. ([source](https://prices.azure.com/api/retail/prices), read 2026-09-06)
- 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.
