Azure Blob Storage is Microsoft’s cloud-based object storage solution designed specifically for storing large amounts of unstructured data—data that does not fit a specific data model or definition, such as text, images, videos, audio files, log files, and binary data.
Key Features and Uses
• Unstructured Data Storage: Blob Storage is ideal for files like documents, images, media, and backups that don’t follow a rigid format.
• Scalability: It can handle massive amounts of data and scale up or down as needed.
• Accessibility: Objects in Blob Storage can be accessed from anywhere in the world over HTTP/HTTPS, via REST APIs, Azure PowerShell, Azure CLI, or client libraries for various programming languages.
• Security: Offers encryption at rest and in transit, role-based access control, and shared access signatures.
• Tiered Storage: Includes hot, cool, and archive access tiers to optimize cost based on how frequently data is accessed.
• Integration: Works seamlessly with other Azure services and third-party applications for analytics, backup, disaster recovery, and content delivery.
How Blob Storage is Structured
• Storage Account: Provides a unique namespace in Azure for your data.
• Container: Acts like a directory within the storage account to organize blobs.
• Blob: The actual file (object) stored in a container. A single container can hold an unlimited number of blobs.
Types of Blobs
• Block Blobs: Best for text and binary data, such as documents or media files.
• Page Blobs: Used for random read/write operations, often for virtual machine disks.
• Append Blobs: Optimized for append operations, such as logging.
Common Use Cases
• Media and File Hosting: Serving images, videos, and documents directly to browsers or applications.
• Backup and Disaster Recovery: Storing backups and archives for resilience.
• Big Data and Analytics: Integration with Azure Data Lake Storage for analytics workloads.
• Log and Event Data: Storing logs and other event data from applications or IoT devices.
