Azure Storage provides multiple services, each with different data models:
* Azure Files
* Provides fully managed file shares accessible via SMB/NFS.
* Works like a traditional file system (folders and files).
* Not key/value.
* Azure Blob Storage
* Object storage for unstructured data like images, videos, backups, logs.
* Identified by container + blob name.
* Not strictly a key/value store (though blob name acts as a key).
* Azure Table Storage #
* A NoSQL key/value store for structured, non-relational data.
* Data is stored in tables as entities (rows), with properties (columns).
* Entities are indexed by PartitionKey + RowKey, forming a unique key/value pair.
* Specifically designed for scalable key/value lookups.
* Azure Queue Storage
* Provides message queueing for communication between components.
* Stores ordered messages, not key/value pairs.
