What is the primary purpose of Azure Blob Storage?

  1. Storing structured data

  2. Storing binary and unstructured data

  3. Storing relational database data

  4. Storing virtual machine images

The correct answer is: Storing binary and unstructured data

The primary purpose of Azure Blob Storage is to store binary and unstructured data. Blob Storage is designed to handle large amounts of unstructured data, which can include documents, images, videos, backups, or any other type of data that does not have a specific structure. This makes it highly versatile for various use cases like web applications, big data analytics, and content distribution. Structured data, such as that found in relational databases, is not the main focus of Blob Storage. For such needs, Azure offers other services like Azure SQL Database or Azure Cosmos DB, which are more suitable for managing structured data. Similarly, while storing virtual machine images can technically be done in Blob Storage, it is not the primary or most efficient purpose of Azure Blob Storage; other services like Azure Disk Storage are specifically designed for VM needs.
