Which Azure Storage service implements the key/value model?

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.

Correct Answer: C. Azure Table
