Azure Storage Solutions – Microsoft AZ-900 Exam

3.3. Azure Storage Solutions

Azure Storage Solutions encompass a suite of services designed to address a wide range of storage needs within the cloud ecosystem. They provide scalable, secure, and performance-optimized options for storing and retrieving large amounts of data, an essential component of both modern cloud applications and traditional systems looking to leverage the benefits of the cloud. From unstructured data such as images and videos to structured data like databases and application files, Azure Storage Solutions offer versatile services tailored to any use case. This comprehensive analysis will delve into the various storage options available within Azure, their functionalities, use cases, and considerations for selection, providing a vital knowledge base for those preparing for the Azure Fundamentals certification and those architecting solutions on the Azure platform.

Understanding Azure Storage Solutions

Azure Storage Solutions is an umbrella term that encompasses several services:

● Azure Blobs: For unstructured data such as text or binary data, including documents, images, and videos.
● Azure Files: Managed file shares for cloud or on-premises deployments.
● Azure Queues: For storing and retrieving large volumes of messages.
● Azure Tables: A NoSQL data store for semi-structured data.
● Azure Disks: Block-level storage volumes for Azure VMs.

Each service is designed to meet different requirements regarding data access patterns, throughput, latency, and scalability.

Azure Blob Storage

Azure Blob Storage is optimized for storing massive amounts of unstructured data. Blobs are grouped into containers that provide a way to organize sets of blobs similar to a directory in a file system. Blob Storage offers three types of blobs:

  1. Block blobs: Ideal for text and binary data, block blobs can be managed individually and are well-suited for items like files and images that are uploaded and downloaded frequently.
  2. Append blobs: Optimized for append operations, making them perfect for logging data from virtual machines.
  3. Page blobs: Designed for frequent read/write operations and are the foundation of Azure virtual machine disks.

Use Cases for Blob Storage

● Data Lakes: Blob Storage can serve as a data lake to store vast amounts of analytics data.
● Content Delivery: It’s used for streaming video and audio, serving images or documents directly to a browser.
● Backup and Restore: Storing backup files for disaster recovery and archiving.
● Storing Data for Cloud-native Applications: Applications can store user data and other operational data.

Key Features of Blob Storage

● Scalability: Store from terabytes to petabytes of data.
● Security: Encrypted to secure data in transit and at rest.
● Global Reach: Can be replicated globally for high availability and redundancy.

Azure Files

Azure Files offers fully managed file shares in the cloud, accessible via the industry-standard Server Message Block (SMB) and Network File System (NFS) protocols. It’s akin to a traditional file server but with the benefits of a cloud provider’s scalability and flexibility.
