Azure Blob storage is a Microsoft storage offering that is meant explicitly for cloud objects and is suitable for holding vast quantities of unstructured data. Unstructured data, such as text or binary data, does not correspond to a specific data model or description.
Blob storage is suitable for sharing images/docs directly to a browser, storing files meant for multiple access, streaming audio/video files, backing up data, creating log files, etc.
There are three types of resources available in blob storage:
A storage account- In Azure, a storage account gives your data its namespace.
A container in the storage account- A container manages a group of blobs, and there are no constraints on the number of blobs stored in a container.
A blob within the container- A blob is a Binary Large Object (BLOB), which can be any form of file or document of any size. Azure supports three different types of Blobs:
Block blobs: These are meant to store individual blocks of text and binary files and have a storage capacity of up to 195GB.
Append blobs: These are useful for append tasks like logging data in log files.
Page blobs: These store random access files up to 8 TiB and are intended for reading/writing operations that occur often.
