# Azure Queue Storage

Canonical: https://inetgeek.com/queues/azure-queue-storage/

Microsoft's managed queue, billed per 10,000 operations with queued messages charged as stored data.

## Who it suits

Azure-resident systems that want a queue billed like storage — operations plus depth, no plan to choose and no capacity to provision.

Consider something else if Queued messages are billed as stored data, so a backlog costs money by the gigabyte-month, and there is no free allowance at all where SQS gives a million requests a month.

## What the documentation says

### Pricing

- Pricing model: Per 10,000 operations plus stored data, with the rate set by redundancy: LRS Class 1 operations are $0.004 per 10,000, ZRS and GRS cost more for the same call. There is no plan fee and no included allowance. ([source](https://prices.azure.com/api/retail/prices), read 2026-09-06)

### Queues

- Included per month: None included — every operation is billed. Class 1 operations are $0.004 per 10,000 on LRS in East US, which is $0.40 per million, matching Amazon SQS's standard rate exactly. ([source](https://prices.azure.com/api/retail/prices), read 2026-09-06)
- Maximum message size: 64 KB per message. A queue may hold millions of messages, bounded only by the storage account's capacity rather than a queue-level ceiling. ([source](https://learn.microsoft.com/en-us/azure/storage/queues/storage-queues-introduction), read 2026-09-06)
- Message retention: Messages in the queue are billed as stored data at $0.045 per GB-month on LRS, rather than granted as a retention window. Azure charges for depth, not for time. ([source](https://prices.azure.com/api/retail/prices), read 2026-09-06)
- Maximum delay: Time-to-live defaults to seven days and can be set to any positive number, or to -1 for a message that never expires — the only queue here with an unbounded option. ([source](https://learn.microsoft.com/en-us/azure/storage/queues/storage-queues-introduction), read 2026-09-06)
