Explanation
When to use Blob Storage
If you need to provision a data store that will store but not query data, your cheapest option is to set up a storage account as a Blob store. Azure Blob storage is Microsoft's object storage solution for the cloud. Blob storage is optimized for storing massive amounts of unstructured data. Unstructured data is data that doesn't adhere to a particular data model or definition, such as text or binary data. Blob storage works well with images and unstructured data, and it's the cheapest way to store data in Azure.
A. Azure Data Lake Storage is optimized for big data analytics and processing large amounts of data. It is not the least expensive option for storing data that will not be queried, as it is designed for more complex data processing scenarios.
B. Azure File Storage is more suitable for storing files that need to be accessed and shared across multiple virtual machines or applications. It is not the most cost-effective option for storing data that will not be queried.
C. Azure Queue Storage is designed for storing messages that are processed asynchronously. It is not intended for storing data that will not be queried, so it is not the least expensive option for this scenario.
D. Azure Cosmos DB Storage is a globally distributed, multi-model database service designed for high availability and scalability. It is not the least expensive option for storing data without querying, as it is more suited for applications that require low-latency access to data.
E. Azure Table Storage is a NoSQL data store that is designed for storing structured data. It is more suitable for scenarios where data needs to be queried, making it a less cost-effective option for storing data without querying requirements.
F. Azure Blob Storage is the least expensive option for storing data without the need for querying. It is ideal for storing unstructured data such as images, videos, and backups, making it a cost-effective choice for this scenario.
G. Azure Database Server Storage is designed for hosting relational databases and is not the most cost-effective option for storing data that will not be queried. It is more suitable for scenarios where data needs to be queried and managed in a relational database system.
