There are two different types of metadata in Azure Storage Blobs: System Properties and User-defined Metadata.
Blob metadata includes both read-only and read-write properties that are valid HTTP headers
There are three types of blobs used in Azure Storage Blobs: Block, Append, and Page.

Append blobs are good for logging and streaming data.

To authorize access to content, you can authenticate in three different ways
You can give them a shared access signature that will grant them specific permissions to the resource for a specified amount of time.
You can configure VMs or cloud services to auto-scale by queue. You can specify the average number of messages to be processed per instance,
