# Azure Blob Storage vs Bunny Storage

Canonical: https://inetgeek.com/compare/azure-blob-vs-bunny-storage/

Every value below is read from Azure Blob Storage's and Bunny Storage's own documentation. See https://inetgeek.com/methodology/ for how.

## At a glance

| Criterion | Azure Blob Storage | Bunny Storage |
| --- | --- | --- |
| 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. | Per region rather than per gigabyte alone: replication is the price axis, so cost scales with how many of Bunny's regions hold a copy. True pay-as-you-go with a $1 monthly minimum and no commitments. |
| 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. | Free to Bunny's own CDN, and no API fees or API egress charges. Bunny prices storage by replication rather than by transfer. |
| 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. | $0.01 per GB per month on Standard HDD for up to two regions, then $0.005 per additional region up to nine. Edge SSD is $0.02 per GB per region across up to fifteen. Three regions on Standard is $0.025 per GB. |
| 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. | None. Bunny states no API fees. |

## Where they differ

### Pricing model

- Azure Blob Storage: 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. ([source](https://prices.azure.com/api/retail/prices))
- Bunny Storage: Per region rather than per gigabyte alone: replication is the price axis, so cost scales with how many of Bunny's regions hold a copy. True pay-as-you-go with a $1 monthly minimum and no commitments. ([source](https://bunny.net/storage/))

### Egress over allowance

- Azure Blob Storage: 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. ([source](https://prices.azure.com/api/retail/prices))
- Bunny Storage: Free to Bunny's own CDN, and no API fees or API egress charges. Bunny prices storage by replication rather than by transfer. ([source](https://bunny.net/storage/))

### Storage price

- Azure Blob Storage: $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))
- Bunny Storage: $0.01 per GB per month on Standard HDD for up to two regions, then $0.005 per additional region up to nine. Edge SSD is $0.02 per GB per region across up to fifteen. Three regions on Standard is $0.025 per GB. ([source](https://bunny.net/storage/))

### Operations price

- Azure Blob Storage: $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))
- Bunny Storage: None. Bunny states no API fees. ([source](https://bunny.net/storage/))

## Which should you choose?

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

Pick Bunny Storage if Assets served from a CDN, where paying per replicated region buys latency you would otherwise build yourself — and traffic to Bunny's CDN costs nothing.

Consider something else: Azure Blob Storage — 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.

Consider something else: Bunny Storage — Replication is the price axis, so multi-region storage costs a multiple of single-region rather than a premium, and it is a CDN origin rather than a general-purpose S3 endpoint.

## Documented by only one

- Storage (entry plan): Azure Blob Storage: 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: Azure Blob Storage: 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.
- SOC 2: Azure Blob Storage: Listed among Azure's compliance offerings (SOC 1, SOC 2, SOC 3) on Microsoft's own compliance documentation — a platform-wide list, not scoped to this specific service.
- ISO 27001: Azure Blob Storage: Listed among Azure's compliance offerings (ISO 27001) on Microsoft's own compliance documentation — a platform-wide list, not scoped to this specific service.
- HIPAA: Azure Blob Storage: Listed among Azure's compliance offerings (HIPAA) on Microsoft's own compliance documentation — a platform-wide list, not scoped to this specific service.
- PCI DSS: Azure Blob Storage: Listed among Azure's compliance offerings (PCI DSS) on Microsoft's own compliance documentation — a platform-wide list, not scoped to this specific service.

## Questions this comparison answers

**Egress over allowance: Azure Blob Storage or Bunny Storage?**

Azure Blob Storage: 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.
Bunny Storage: Free to Bunny's own CDN, and no API fees or API egress charges. Bunny prices storage by replication rather than by transfer.
