Azure - Blob Storage

Introduction

• Azure Blob Storage is a service for storing large amounts of unstructured data, such as text or binary data, that can be accessed via HTTP or HTTPS.
• It is optimized for storing massive amounts of data and provides scalability, security, and cost-efficiency.

Different Types of Azure Blob Storage

1. Block Blobs
   • Purpose: Stores text and binary data, ideal for large objects like media files, documents, and backups.
   • Features: Supports uploading large files efficiently in smaller blocks and can manage individual blocks.
2. Append Blobs
   • Purpose: Optimized for append operations, suitable for log data and data streaming scenarios.
   • Features: Designed for scenarios where data is added sequentially, such as logging or data collection.
3. Page Blobs
   • Purpose: Stores random-access files, ideal for use as disks for virtual machines (Azure VMs).
   • Features: Supports frequent read/write operations, making it suitable for disk storage and other I/O intensive applications.
4. Immutable Blob Storage
   • Immutable Blob Storage is a feature in Azure Blob Storage that allows you to store data in a write-once, read-many (WORM) manner, ensuring that once data is written, it cannot be modified or deleted for a specified retention period.
   • This feature is commonly used for compliance, regulatory, and data protection purposes, where data integrity and immutability are critical requirements.
