Azure Blob Storage is a service provided by Microsoft Azure that allows you to store large amounts of unstructured data. This includes text files, images, videos, documents, backups, and even big data files. "Blob" stands for Binary Large Object.
It is widely used for:
Storing files for web apps
Backups and disaster recovery
Streaming audio and video
Storing data for analytics and machine learning

Whether you are a developer, data engineer, or system administrator, knowing how to work with Azure Blob Storage is a key cloud skill. It supports:
Scalability – Store petabytes of data without worrying about capacity
Security – Built-in encryption and access control
Cost-efficiency – Pay only for what you use
Integration – Works well with other Azure services like Azure Data Factory, Azure Functions, and Azure Synapse Analytics
Key Concepts You Should Know
Before diving into hands-on steps, here are a few important terms:
Storage Account: The top-level container for your data
Container: Like a folder that holds your blobs
Blob: The actual data file. There are three types:
Block blobs (for most files)
Append blobs (for logs)
Page blobs (for virtual disks)
