What storage solution is ideal for preserving logs and generating reports based on access data stored in Azure?

1. Azure Blob Storage

2. Azure Table Storage

3. Azure SQL Database

4. Azure Storage Queue

The correct answer is: Azure Blob Storage

Azure Blob Storage is particularly suited for preserving logs and generating reports based on access data stored in Azure due to several key features it offers. Blob Storage is designed to handle large volumes of unstructured data, such as logs, images, videos, and other files, making it ideal for applications that require the storage of raw data in a cost-effective manner. The ability to store data in a flat namespace allows for easy organization of logs, and the use of tiered storage options (like hot, cool, and archive tiers) offers flexibility in managing costs based on access frequency. This becomes essential when dealing with logs, as not all log data needs to be accessed frequently; older logs can be moved to the cooler tiers to save on costs while still preserving them for compliance, auditing, or reporting purposes. Additionally, Azure Blob Storage supports advanced features like versioning and immutability, which can ensure that log data remains unchanged for a specified retention period, enhancing compliance and integrity for audit purposes. Using Azure Blob Storage with integration from other services like Azure Data Lake or Azure Stream Analytics enables advanced analytics and reporting on log data, making it easy to create dashboards, alerts, and insights based on historical access patterns. While Azure Table Storage is also capable of handling
