Blob storage account

Unlike a general-purpose storage account, not all Azure Storage services are meant to be stored in a Blob storage account because they are dedicated to storing unstructured data. Therefore, a Blob storage service is the only type allowed to be accessed by a Blob storage account. However, it only supports blocks and appends blobs.

A Blob storage account has a usage pattern called access tiers, which determines how frequently you access your data and, based on that, what you will get billed. Currently, there are three types:

• Hot access tier
• Cool access tier
• Archive access tier
