What type of Azure Storage account should you deploy to store data for multiple users, ensuring each user's data is encrypted with a separate key?

The most suitable choice for storing data for multiple users, with each user's data encrypted with a separate key, is a general purpose v2 storage account containing blobs.

A general purpose v2 storage account supports various services like blob storage, file storage, queue storage, and table storage, providing versatility in data management. Specifically, when it comes to blobs, Azure allows for the use of Customer Managed Keys (CMK) for encryption, which enables you to encrypt individual blobs with different keys. This feature aligns perfectly with the requirement of having separate keys for each user's data, ensuring that each user’s information is secured according to their specific needs.

While premium file share storage accounts offer advantages such as high performance and low latency for file shares, they do not provide the same level of customization for encryption keys at the individual user level. Similarly, Azure Data Lake Storage Gen2 is designed for big data analytics, and although it offers some key management features, the specific requirement for managing separate keys for each user’s data fits more naturally within the blob storage capabilities of a general purpose v2 account.

Overall, the general purpose v2 storage account stands out for scenarios that require robust handling of user data with fine-grained security controls, such as separate encryption keys for
