Azure Storage SDK Introduction

Welcome to the Azure Storage SDK

The Azure Storage SDKs provide a powerful and flexible way to interact with Azure Storage services from your applications. Whether you're building a cloud-native application, migrating an existing workload, or developing a mobile app, our SDKs offer robust features and intuitive APIs to manage your data.

What are Azure Storage SDKs?

Azure Storage offers several types of storage services:

Blob Storage: Scalable object storage for unstructured data like documents, images, videos, and backups.
File Storage: Fully managed cloud file shares accessible via the industry-standard Server Message Block (SMB) protocol.
Queue Storage: A service for storing large numbers of messages that can be accessed from anywhere in the world.
Table Storage: A NoSQL key-attribute store for structured non-relational data.

Our SDKs are available for various popular programming languages and platforms, including:

.NET
Java
Python
JavaScript/TypeScript
Go
C++

Getting Started with the SDK

To begin using the Azure Storage SDK, you'll typically need to:

Install the SDK package: Use your language's package manager (e.g., NuGet for .NET, pip for Python, npm for Node.js).
Obtain connection information: You'll need your Azure Storage account name and either a connection string or access keys.
Instantiate a client: Create a client object for the specific storage service you want to interact with (e.g., BlobServiceClient, QueueClient).
Perform operations: Use the client to perform operations like uploading/downloading files, sending/receiving messages, or querying tables.

Example: Uploading a Blob (Python)

Here's a simple example demonstrating how to upload a blob to Azure Blob Storage using the Python SDK:


from azure.storage.blob import BlobServiceClient

# Replace with your actual connection string
connect_str = "YOUR_AZURE_STORAGE_CONNECTION_STRING"
container_name = "my-container"
local_file_name = "local_file.txt"
blob_name = "remote_blob_name.txt"

try:
    # Create the BlobServiceClient object
    blob_service_client = BlobServiceClient.from_connection_string(connect_str)

    # Get a client to interact with a specific container
    container_client = blob_service_client.get_container_client(container_name)

    # Create a local file for demonstration
    with open(local_file_name, "w") as my_file:
        my_file.write("This is a sample file to upload.")

    # Upload the blob
    with open(local_file_name, "rb") as data:
        blob_client = container_client.upload_blob(name=blob_name, data=data, overwrite=True)
        print(f"Blob '{blob_name}' uploaded successfully.")

except Exception as ex:
    print('Exception: {}'.format(ex))

Key Features

Asynchronous Operations: Many SDKs offer asynchronous APIs for improved performance and responsiveness.
Error Handling: Comprehensive error handling and exceptions for robust applications.
Retry Policies: Built-in retry mechanisms to handle transient network issues.
Cross-Platform Compatibility: Works across various operating systems and environments.
Security: Support for various authentication methods, including shared key, Shared Access Signatures (SAS), and Azure Active Directory.
