Which Azure Storage service implements the key/value model?

Azure Files provides fully managed file shares in the cloud, accessible via SMB or NFS protocols, and is not a key/value store.

Azure Blob storage is optimized for storing massive amounts of unstructured object data, such as text or binary data, but it uses containers and blobs, not a key/value data model at the primary storage level.

Azure Table storage is a NoSQL key/attribute store that uses a schema-less design, where data is organized as tables and rows, and each row is uniquely identified by a combination of PartitionKey and RowKey, forming a key/value structure.

Azure Queue storage is used for storing large numbers of messages that can be accessed from anywhere in the world, acting as a message queue service, not a persistent key/value data store.
