Blob Service REST API
The Blob service stores text and binary data. The Blob service offers the following three resources: the storage account, containers, and blobs. Within your storage account, containers provide a way to organize sets of blobs.
You can store text and binary data in either of two types of blobs:
-
Block blobs, which are optimized for streaming.
-
Page blobs, which are optimized for random read/write operations and which provide the ability to write to a range of bytes in a blob.
For more information about block blobs and page blobs, see Understanding Block Blobs and Page Blobs.
The REST API for the Blob service provides a way to work with container and blob resources via HTTP operations. The API includes the operations listed in the following table.
