Technical Architecture Overview

Azure storage services are built on a massively scalable architecture that provides high availability and durability. The architecture is designed to handle a wide range of data types and workloads. Here’s a brief overview of the main Azure storage services:

  • Azure Blob Storage: Ideal for storing unstructured data such as text or binary data. It is commonly used for serving images or documents directly to a browser, storing files for distributed access, streaming video and audio, and storing data for backup and restore, disaster recovery, and archiving.

  • Azure File Storage: Provides fully managed file shares in the cloud that are accessible via the Server Message Block (SMB) protocol. It can be used to replace or supplement on-premises file servers or NAS devices.

  • Azure Queue Storage: A service for storing large numbers of messages that can be accessed from anywhere in the world via authenticated calls using HTTP or HTTPS. It is often used to create a backlog of work to process asynchronously.

  • Azure Table Storage: A NoSQL store for schemaless storage of structured data. It is a key-attribute store that allows for rapid development and fast access to large quantities of data.

  • Azure Disk Storage: Provides disks for Azure virtual machines. It includes both managed and unmanaged disks, offering high-performance, durable block storage.

To make a well-informed decision on which storage service to use, it is important to understand the specific requirements of your application and the characteristics of each storage service.

Troubleshooting & Monitoring

Effective troubleshooting and monitoring are essential for maintaining the health and performance of your Azure storage services. Azure provides several tools and features for this purpose.

1. Azure Monitor

Azure Monitor provides a comprehensive set of monitoring tools for Azure resources, including storage accounts.

  • Metrics: Azure Monitor collects metrics such as transaction counts, latency, and availability for your storage accounts. You can view these metrics in the Azure portal under the "Monitoring" section of your storage account.

  • Logs: Azure Monitor can also collect logs for your storage accounts, which include detailed information about requests made to your storage account. You can enable diagnostic settings to send logs to Azure Monitor Logs (Log Analytics), Azure Storage, or Azure Event Hubs.

2. Azure Storage Analytics

Storage Analytics provides logging and metrics for Azure storage accounts. It can help you diagnose issues and understand how your storage account is being used.

  • Logging: Storage Analytics logs detailed information about successful and failed requests to your storage account. Logs are stored in blobs within a container named $logs in your storage account.

  • Metrics: Storage Analytics provides aggregated transaction and capacity metrics for Blob, Table, and Queue services. Metrics are stored in tables within your storage account.

3. Alerts

You can set up alerts in Azure Monitor to notify you when specific conditions are met, such as when a storage account reaches a certain capacity threshold or when there is a high number of failed requests.

  1. Navigate to your storage account in the Azure portal.
  2. Under the "Monitoring" section, click on "Alerts."
  3. Click on "+ New alert rule" and define the condition (e.g., "Transactions" metric is greater than a certain value).
