Azure Blob Storage

Azure Blob Storage is Microsoft's object storage solution for the cloud. It is designed to store massive amounts of unstructured data — text, images, videos, logs, backups, and any binary data. This lesson covers the core concepts of Blob Storage, blob types, containers, access patterns, and common use cases.
