Day 6 – Introduction to Azure Storage (Blob, File, Queue, Table)

Introduction

Azure Storage is the foundation for building scalable, secure, and high-performance cloud applications. Whether you are storing unstructured files, structured tables, messages for processing, or shared files, Azure Storage offers tailored services.

At curiositytech.in, we emphasize learning by hands-on experimentation, allowing learners to explore storage options in real projects. This blog covers all mandatory details of Azure Storage, comparing Blob, File, Queue, and Table storage, along with use cases, best practices, and tips for experts.

1. Overview of Azure Storage Services

Azure Storage provides four main types of storage services:

Storage Type	Purpose	Key Features	Use Case Example
Blob Storage	Store unstructured data (files, images, videos)	Tiered storage, replication, versioning	Hosting website images, backups
File Storage	Fully managed file shares in the cloud	SMB/NFS access, snapshot support	Shared drives for enterprise teams
Queue Storage	Messaging between application components	Reliable FIFO message delivery, scalable	Decoupling microservices
Table Storage	NoSQL key-value storage for structured data	Schema-less, fast access, low cost	Storing IoT sensor data, logs

2. Azure Blob Storage: Unstructured Data Storage

• Definition: Blob Storage is designed to store any type of unstructured data.
  
  
• Types of Blobs:
  
  
  • Block Blobs – Ideal for text or binary files, supports large file uploads
    
    
  • Append Blobs – Optimized for append-only workloads (logs)
    
    
  • Page Blobs – Used for random read/write operations (VHDs)
    
    

Practical Use Case:
 A media company stores video content in Blob Storage, leveraging hot, cool, and archive tiers to optimize cost based on access frequency.

Tip: Always define the correct access tier during deployment to reduce storage costs.

3. Azure File Storage: Shared File Access

• Definition: Fully managed file shares accessible via SMB or NFS protocols.
  
  
• Benefits:
  
  
  • Centralized file access
    
    
  • Integrates with Windows/Linux environments
    
    
  • Snapshots for point-in-time recovery
    
    

Practical Example:
 Teams in a corporation share a directory of project documents via Azure File Share. Developers can mount the share directly on their machines as a network drive.

4. Azure Queue Storage: Decoupled Messaging

• Definition: Provides reliable, scalable message queuing for cloud applications.
  
  
• Key Features:
  
  
  • FIFO message delivery
    
    
  • Supports large-scale applications
    
    
  • Helps decouple microservices for better reliability
    
    

Scenario:
 An e-commerce application uses queues to process orders asynchronously. The frontend pushes order messages to the queue, and backend services process them independently, ensuring system resilience during high traffic.

5. Azure Table Storage: Structured, NoSQL Storage

• Definition: Table Storage is a schema-less, key-value storage for structured data.
  
  
• Advantages:
  
  
  • High-speed lookups
    
    
  • Cost-effective for massive datasets
    
    
  • Supports large-scale telemetry and logging
    
    

Use Case Example:
 IoT sensors send millions of telemetry events per day. Table Storage stores this structured data efficiently, allowing fast queries by device ID or timestamp.

6. Comparative View: Choosing the Right Storage

Storage Type	Best For	Access Method	Performance Tier
Blob	Files, images, backups	REST API, SDK, AzCopy	Hot, Cool, Archive
File	Shared directories	SMB/NFS	Standard / Premium
Queue	Messaging between apps	REST API, SDK	Standard
Table	Structured NoSQL data	REST API, SDK	Standard

 4. Practical Tip: Use Azure CLI or PowerShell for scripting repetitive storage tasks. For

8. Expert Tips to Become an Azure Storage Specialist

1. Understand tiering options (hot, cool, archive) and their pricing impact.
   
   
2. Learn storage replication strategies: LRS, GRS, RA-GRS for durability.
   
   
3. Automate backups and snapshots using Azure Backup and Storage Explorer.
   
   
4. Explore Azure Storage security: Shared Access Signatures (SAS), RBAC, encryption at rest.
   
   
5. Combine storage services in real projects to simulate enterprise scenarios (e.g., Blob for media, Queue for tasks, Table for logs).
