When designing applications for Azure, what storage option should be chosen for optimal read and cost-efficiency for large file storage?

Azure Blob Storage is the optimal choice for storing large files due to its high scalability, cost-effectiveness, and tailored functionality for handling unstructured data such as documents, images, videos, and backups. It is designed specifically for massive amounts of unstructured data, allowing users to easily store and retrieve large blobs of data.

The billing model of Azure Blob Storage is also beneficial for cost efficiency since it typically charges based on the amount of data stored and the data access patterns. When compared to other storage solutions, such as Azure Files or Azure SQL Database, Blob Storage generally incurs lower costs for large volumes of data and offers tiered storage options (hot, cool, and archive) that can further optimize costs depending on access frequency.

Furthermore, Azure Blob Storage provides high availability and redundancy options, ensuring that large files can be accessed reliably. It also integrates seamlessly with various Azure services, enabling efficient data management and processing. This capability makes it particularly suitable for applications requiring optimal read performance and economical storage mechanisms for large files.
