Archive Storage offers the lowest storage costs of all Azure storage. Its retrieval costs, however, are higher when compared to Hot and Cool storage. The archive tier of storage is designed for data that can tolerate several hours of latency when being retrieved. It’s also meant for data that will remain in the archive tier for at least 180 days.
Data blobs in Archive Storage are offline and they cannot be read, copied, overwritten, or modified. While you cannot take snapshots of blobs that are stored in Archive Storage, you can delete data blobs, list them, retrieve blob properties/metadata, and change the tier of them.
Archive Storage is typically used for things like long-term backups and data archiving. It can also be used for secondary backups as well. It also is useful for compliance data or archival data that needs to be kept around for a long time, while hardly ever being accessed (e.g., security camera footage).
Azure Queue Storage is a solution for storing large numbers of messages that might need to be accessible from anywhere in the world via HTTP or HTTPS. Each queue message can be no larger than 64 KB. A queue, itself, can contain millions of messages — and it can host as many messages as it takes to fill the capacity of the storage account hosting the data.
