Introduction to Azure Storage
Azure Storage is a cloud storage solution that supports data for quick and easy access. It's designed to be highly available, secure, and scalable. Azure Storage offers a range of services to meet diverse data storage needs, from unstructured data like text and binary to structured data and massive datasets.
This documentation provides an overview of the core Azure Storage services, their use cases, and how to get started with them. Whether you're building a new application or migrating existing data, Azure Storage provides the robust foundation you need.
Azure Blob Storage
Azure Blob Storage is Microsoft's object storage solution for the cloud. It's optimized for storing massive amounts of unstructured data, such as text or binary data. You can use Blob Storage to serve images or documents directly to a browser, store files for distributed access, stream video and audio, write to backup and restore log files, store data for analysis, and more.
Blob Storage Tiers:
- Hot tier: Optimized for frequently accessed data.
- Cool tier: Optimized for infrequently accessed data.
- Archive tier: Optimized for rarely accessed data with flexible latency requirements.
Example: Uploading a file to Blob Storage (Conceptual)
Using the Azure CLI:
az storage blob upload --account-name --container-name --name --file --auth-mode login
Azure Files
Azure Files provides fully managed cloud file shares that are accessible via the industry-standard Server Message Block (SMB) protocol. You can "mount" an Azure Files share on-premises or in the cloud, just as you would mount a Windows file share. This makes it ideal for scenarios like replacing or supplementing on-premises file servers, managing application settings, or sharing configuration files.
Azure Queue Storage
Azure Queue Storage is a service that stores large numbers of messages that can be processed asynchronously. Each message in a queue is typically 64 KB in size, and a storage account can contain thousands of messages. Queue Storage is commonly used to decouple components of cloud applications and manage communication between them.
Azure Table Storage
Azure Table Storage is a NoSQL key-attribute store that accepts authenticated calls through HTTP or HTTPS. Table Storage is ideal for storing large amounts of structured, non-relational data. It's a flexible and scalable solution for various data storage needs.
Azure Managed Disks
Azure Managed Disks are the recommended way to manage storage for Azure virtual machines. Managed Disks are block-level storage volumes that are managed by Azure and are used for VMs. The types of managed disks include Ultra Disk, Premium SSD, Standard SSD, and Standard HDD, each offering different performance and cost characteristics.
Azure Data Lake Storage Gen2
Azure Data Lake Storage Gen2 is a set of capabilities dedicated to big data analytics, built on Azure Blob Storage. It's optimized for high-performance analytics workloads, offering a hierarchical namespace that enables efficient data access patterns. This service is crucial for data scientists and big data engineers working with large datasets.
Managing Azure Storage
Azure provides several tools for managing your storage resources:
- Azure Portal: A web-based interface for managing all your Azure resources.
- Azure CLI: A command-line tool for managing Azure resources.
- Azure PowerShell: Another command-line tool for managing Azure resources.
- Azure Storage Explorer: A standalone app that enables you to easily manage your Azure cloud storage resources from your desktop.
Security is paramount. Azure Storage supports various security features, including Azure Active Directory integration, shared access signatures (SAS), and encryption at rest and in transit.
